Cycles: Make all #include statements relative to cycles source directory The idea is to make include statements more explicit and obvious where the file is coming from, additionally reducing chance of wrong header being picked up. For example, it was not obvious whether bvh.h was refferring to builder or traversal, whenter node.h is a generic graph node or a shader node and cases like that. Surely this might look obvious for the active developers, but after some time of not touching the code it becomes less obvious where file is coming from. This was briefly mentioned in T50824 and seems @brecht is fine with such explicitness, but need to agree with all active developers before committing this. Please note that this patch is lacking changes related on GPU/OpenCL support. This will be solved if/when we all agree this is a good idea to move forward.

Cycles: Added Cryptomatte output. This allows for extra output passes that encode automatic object and material masks for the entire scene. It is an implementation of the Cryptomatte standard as introduced by Psyop. A good future extension would be to add a manifest to the export and to do plenty of testing to ensure that it is fully compatible with other renderers and compositing programs that use Cryptomatte. Internally, it adds the ability for Cycles to have several passes of the same type that are distinguished by their name. Differential Revision: https://developer.blender.org/D3538

Fix T82129: Cycles "Persistent Images" incorrectly retains scene data The issue stems from the fact that scene arrays are not cleared when rendering is done. This was not really an issue before the introduction of the ownership system (rB429afe0c626a) as the id_map would recreate scene data arrays based on their new content. However, now that the id_maps do not have access to the scene data anymore the arrays are never created. Another related issue is that the BlenderSync instance is never freed when the persistent data option is activated. To fix this, we delete nodes created by the id_maps in their destructors, and delete the BlenderSync instance before creating a new one, so the id_maps destructors are actually called.

Cycles: experimental integration of Alembic procedural in viewport rendering This patch exposes the Cycles Alembic Procedural through the MeshSequenceCache modifier in order to use and test it from Blender. To enable it, one has to switch the render feature set to experimental and activate the Procedural in the modifier. An Alembic Procedural is then created for each CacheFile from Blender set to use the Procedural, and each Blender object having a MeshSequenceCache modifier is added to list of objects of the right procedural. The procedural's parameters derive from the CacheFile's properties which are already exposed in the UI through the modifier, although more Cycles specific options might be added in the future. As there is currently no cache controls and since we load all the data at the beginning of the render session, the procedural is only available during viewport renders at the moment. When an Alembic procedural is rendered, data from the archive are not read on the Blender side. If a Cycles render is not active and the CacheFile is set to use the Cycles Procedural, bounding boxes are used to display the objects in the scene as a signal that the objects are not processed by Blender anymore. This is standard in other DCCs. However this does not reduce the memory usage from Blender as the Alembic data was already loaded either during an import or during a .blend file read. This is mostly a hack to test the Cycles Alembic procedural until we have a better Blender side mechanism for letting renderers load their own geometry, which will be based on import and export settings on Collections (T68933).

Cycles: Avoid unnecessary data updates in viewport The BlenderSync will do quite a bit of work on every sync_data() call even if there is nothing changed in the scene. There will be early outputs done deeper in the call graph, but this is not really enough to ensure best performance during viewport navigation. This change makes it so sync_data() is only used when dependency graph has any update tags: if something changed in the scene the dependency graph will know it. If nothing changed there will be no IDs tagged for an update in the dependency graph. There are two weak parts in the current change: - With the persistent data there is a special call to ignore the check of the dependency graph tags. This is more of a safety, because it is not immediately clear what the correct state of recalc flags is. - Deletion of objects is detected indirectly, via tags of scene and collections. It might not be bad for the first version of the change. The test file used: {F10117322} Simply open the file, start viewport render, and navigate the viewport. On my computer this avoids 0.2sec spend on data_sync() on every up[date of viewport navigation. We can do way more granular updates in the future: for example, avoid heavy objects sync when it is only camera object which changed. This will need an extended support from the dependency graph API. Doing nothing if nothing is changed is something we would want to do anyway. Differential Revision: https://developer.blender.org/D11279

Shading Modes: Material and Render Preview This change implements the basics as described in {T68312} for the shading modes. * LookDev shading mode is renamed to Material Preview. It always uses Eevee as renderer, and is intended to provide a fast material preview suitable for texture painting, and texture and material setup. * Rendered shading gains "Use Scene Lights" and "Use Scene World" options similar to current Material Preview. These will be enabled by default. When Use Scene World is turned off, HDRIs will be used for lighting instead. These options are available for EEVEE and Cycles. * Renderers will be able to customize the shading settings panel and add additional settings.

Fix missing Cycles 3D viewport updates when editing materials, lamps. This introduces a new depsgraph API for getting updated datablocks, rather than getting it from bpy.data. * depsgraph.ids_updated gives a list of all datablocks in the depsgraph which have been updated. * depsgraph.id_type_updated('TYPE') is true if any datablock of the given type has been added, removed or modified. More API updates are coming to properly handle multiple depsgraphs and finer update granularity, but this should make Cycles work again.

Cycles: Avoid unnecessary data updates in viewport The BlenderSync will do quite a bit of work on every sync_data() call even if there is nothing changed in the scene. There will be early outputs done deeper in the call graph, but this is not really enough to ensure best performance during viewport navigation. This change makes it so sync_data() is only used when dependency graph has any update tags: if something changed in the scene the dependency graph will know it. If nothing changed there will be no IDs tagged for an update in the dependency graph. There are two weak parts in the current change: - With the persistent data there is a special call to ignore the check of the dependency graph tags. This is more of a safety, because it is not immediately clear what the correct state of recalc flags is. - Deletion of objects is detected indirectly, via tags of scene and collections. It might not be bad for the first version of the change. The test file used: {F10117322} Simply open the file, start viewport render, and navigate the viewport. On my computer this avoids 0.2sec spend on data_sync() on every up[date of viewport navigation. We can do way more granular updates in the future: for example, avoid heavy objects sync when it is only camera object which changed. This will need an extended support from the dependency graph API. Doing nothing if nothing is changed is something we would want to do anyway. Differential Revision: https://developer.blender.org/D11279

Additionally, I changed it so that a BObjectInfo is passed into `object_is_geometry` to make it more explicit when this method is supposed to be used.

Attribute Node: support accessing attributes of View Layer and Scene. The attribute node already allows accessing attributes associated with objects and meshes, which allows changing the behavior of the same material between different objects or instances. The same idea can be extended to an even more global level of layers and scenes. Currently view layers provide an option to replace all materials with a different one. However, since the same material will be applied to all objects in the layer, varying the behavior between layers while preserving distinct materials requires duplicating objects. Providing access to properties of layers and scenes via the attribute node enables making materials with built-in switches or settings that can be controlled globally at the view layer level. This is probably most useful for complex NPR shading and compositing. Like with objects, the node can also access built-in scene properties, like render resolution or FOV of the active camera. Lookup is also attempted in World, similar to how the Object mode checks the Mesh datablock. In Cycles this mode is implemented by replacing the attribute node with the attribute value during sync, allowing constant folding to take the values into account. This means however that materials that use this feature have to be re-synced upon any changes to scene, world or camera. The Eevee version uses a new uniform buffer containing a sorted array mapping name hashes to values, with binary search lookup. The array is limited to 512 entries, which is effectively limitless even considering it is shared by all materials in the scene; it is also just 16KB of memory so no point trying to optimize further. The buffer has to be rebuilt when new attributes are detected in a material, so the draw engine keeps a table of recently seen attribute names to minimize the chance of extra rebuilds mid-draw.

Fix for #32184 and redesign of particle storage in Cycles. The particle data used by the Particle Info node was stored in cycles as a list in each object. This is a problem when the particle emitter mesh is hidden: Objects in cycles are only intended as instances of renderable meshes, so when hiding the emitter mesh the particle data doesn't get stored either. Also the particle data can potentially be copied to multiple instances of the same object, which is a waste of texture space. The solution in this patch is to make a completely separate list of particle systems in the Cycles scene data. This way the particle data can be generated even when the emitter object itself is not visible.

Render: faster animation and re-rendering with Persistent Data For Cycles, when enabling the Persistent Data option, the full render data will be preserved from frame-to-frame in animation renders and between re-renders of the scene. This means that any modifier evaluation, BVH building, OpenGL vertex buffer uploads, etc, can be done only once for unchanged objects. This comes at an increased memory cost. Previously there option was named Persistent Images and had a more limited impact on render time and memory. When using multiple view layers, only data from a single view layer is preserved to keep memory usage somewhat under control. However objects shared between view layers are preserved, and so this can speedup such renders as well, even single frame renders. For Eevee and Workbench this option is not available, however these engines will now always reuse the depsgraph for animation and multiple view layers. This can significantly speed up rendering. These engines do not support sharing the depsgraph between re-renders, due to technical issues regarding OpenGL contexts. Support for this could be added if those are solved, see the code comments for details.

Cycles: Avoid unnecessary data updates in viewport The BlenderSync will do quite a bit of work on every sync_data() call even if there is nothing changed in the scene. There will be early outputs done deeper in the call graph, but this is not really enough to ensure best performance during viewport navigation. This change makes it so sync_data() is only used when dependency graph has any update tags: if something changed in the scene the dependency graph will know it. If nothing changed there will be no IDs tagged for an update in the dependency graph. There are two weak parts in the current change: - With the persistent data there is a special call to ignore the check of the dependency graph tags. This is more of a safety, because it is not immediately clear what the correct state of recalc flags is. - Deletion of objects is detected indirectly, via tags of scene and collections. It might not be bad for the first version of the change. The test file used: {F10117322} Simply open the file, start viewport render, and navigate the viewport. On my computer this avoids 0.2sec spend on data_sync() on every up[date of viewport navigation. We can do way more granular updates in the future: for example, avoid heavy objects sync when it is only camera object which changed. This will need an extended support from the dependency graph API. Doing nothing if nothing is changed is something we would want to do anyway. Differential Revision: https://developer.blender.org/D11279

Cycles: Free unused image buffers when rendering with locked interface It is still possible to free a bit more memory by detecting buildin images which are not used by shaders, but that's not going to improve memory usage that much to bother about this now. Such change brings peak memory usage from 4.1GB to 3.4GB when rendering 01_01_01_D layout scene from the Gooseberry project. Mainly because of freeing memory used by rather huge environment map in the viewport.

Cycles: add support for volume motion blur This adds support for rendering motion blur for volumes, using their velocity field. This works for fluid simulations and imported VDB volumes. For the latter, the name of the velocity field can be set per volume object, with automatic detection of velocity fields that are split into 3 scalar grids. A new parameter is also added to scale velocity for more artistic control. Like for Alembic and USD caches, a parameter to set the unit of time in which the velocity vectors are expressed is also added. For Blender gas simulations, the velocity unit should always be in seconds, so this is only exposed for volume objects which may come from external OpenVDB files. These parameters are available under the `Render` panels for the fluid domain and the volume object data properties respectively.

Fix T82129: Cycles "Persistent Images" incorrectly retains scene data The issue stems from the fact that scene arrays are not cleared when rendering is done. This was not really an issue before the introduction of the ownership system (rB429afe0c626a) as the id_map would recreate scene data arrays based on their new content. However, now that the id_maps do not have access to the scene data anymore the arrays are never created. Another related issue is that the BlenderSync instance is never freed when the persistent data option is activated. To fix this, we delete nodes created by the id_maps in their destructors, and delete the BlenderSync instance before creating a new one, so the id_maps destructors are actually called.

Cycles API: encapsulate Node socket members This encapsulates Node socket members behind a set of specific methods; as such it is no longer possible to directly access Node class members from exporters and parts of Cycles. The methods are defined via the NODE_SOCKET_API macros in `graph/ node.h`, and are for getting or setting a specific socket's value, as well as querying or modifying the state of its update flag. The setters will check whether the value has changed and tag the socket as modified appropriately. This will let us know how a Node has changed and what to update, which is the first concrete step toward a more granular scene update system. Since the setters will tag the Node sockets as modified when passed different data, this patch also removes the various modified methods on Nodes in favor of Node::is_modified which checks the sockets' update flags status.

Cycles: Implement blue-noise dithered sampling This patch implements blue-noise dithered sampling as described by Nathan Vegdahl (https://psychopath.io/post/2022_07_24_owen_scrambling_based_dithered_blue_noise_sampling), which in turn is based on "Screen-Space Blue-Noise Diffusion of Monte Carlo Sampling Error via Hierarchical Ordering of Pixels"(https://repository.kaust.edu.sa/items/1269ae24-2596-400b-a839-e54486033a93). The basic idea is simple: Instead of generating independent sequences for each pixel by scrambling them, we use a single sequence for the entire image, with each pixel getting one chunk of the samples. The ordering across pixels is determined by hierarchical scrambling of the pixel's position along a space-filling curve, which ends up being pretty much the same operation as already used for the underlying sequence. This results in a more high-frequency noise distribution, which appears smoother despite not being less noisy overall. The main limitation at the moment is that the improvement is only clear if the full sample amount is used per pixel, so interactive preview rendering and adaptive sampling will not receive the benefit. One exception to this is that when using the new "Automatic" setting, the first sample in interactive rendering will also be blue-noise-distributed. The sampling mode option is now exposed in the UI, with the three options being Blue Noise (the new mode), Classic (the previous Tabulated Sobol method) and the new default, Automatic (blue noise, with the additional property of ensuring the first sample is also blue-noise-distributed in interactive rendering). When debug mode is enabled, additional options appear, such as Sobol-Burley. Note that the scrambling distance option is not compatible with the blue-noise pattern.

Cycles: Implement blue-noise dithered sampling This patch implements blue-noise dithered sampling as described by Nathan Vegdahl (https://psychopath.io/post/2022_07_24_owen_scrambling_based_dithered_blue_noise_sampling), which in turn is based on "Screen-Space Blue-Noise Diffusion of Monte Carlo Sampling Error via Hierarchical Ordering of Pixels"(https://repository.kaust.edu.sa/items/1269ae24-2596-400b-a839-e54486033a93). The basic idea is simple: Instead of generating independent sequences for each pixel by scrambling them, we use a single sequence for the entire image, with each pixel getting one chunk of the samples. The ordering across pixels is determined by hierarchical scrambling of the pixel's position along a space-filling curve, which ends up being pretty much the same operation as already used for the underlying sequence. This results in a more high-frequency noise distribution, which appears smoother despite not being less noisy overall. The main limitation at the moment is that the improvement is only clear if the full sample amount is used per pixel, so interactive preview rendering and adaptive sampling will not receive the benefit. One exception to this is that when using the new "Automatic" setting, the first sample in interactive rendering will also be blue-noise-distributed. The sampling mode option is now exposed in the UI, with the three options being Blue Noise (the new mode), Classic (the previous Tabulated Sobol method) and the new default, Automatic (blue noise, with the additional property of ensuring the first sample is also blue-noise-distributed in interactive rendering). When debug mode is enabled, additional options appear, such as Sobol-Burley. Note that the scrambling distance option is not compatible with the blue-noise pattern.

The current implementation supports guiding directional sampling decisions on surfaces, when the material contains a least one diffuse component, and in volumes with isotropic and anisotropic Henyey-Greenstein phase functions.

/* UPDATE_NONE as we don't want to tag the integrator as modified (this was done by the
* set calls above), but we need to make sure that the dependent things are tagged. */
Cycles: optimize device updates This optimizes device updates (during user edits or frame changes in the viewport) by avoiding unnecessary computations. To achieve this, we use a combination of the sockets' update flags as well as some new flags passed to the various managers when tagging for an update to tell exactly what the tagging is for (e.g. shader was modified, object was removed, etc.). Besides avoiding recomputations, we also avoid resending to the devices unmodified data arrays, thus reducing bandwidth usage. For OptiX and Embree, BVH packing was also multithreaded. The performance improvements may vary depending on the used device (CPU or GPU), and the content of the scene. Simple scenes (e.g. with no adaptive subdivision or volumes) rendered using OptiX will benefit from this work the most. On average, for a variety of animated scenes, this gives a 3x speedup.

Cycles: Display RenderPass in Viewport This change allows the user to select a renderpass in the 3d viewport. Added support for external renderers to extend the `View3DShading` struct. This way Blender doesn't need to know the features an external render engine wants to support. Note that the View3DShading is also available in the scene->display.shading; although this is supported, it does not make sense for render engines to put something here as it is really scene/workbench related. Currently cycles assumes that it always needs to calculate the combined pass; it ignores the `pass_flag` in KernelFilm. We could optimize this but that was not in scope of this change Reviewed By: brecht Differential Revision: https://developer.blender.org/D5689

Cycles API: encapsulate Node socket members This encapsulates Node socket members behind a set of specific methods; as such it is no longer possible to directly access Node class members from exporters and parts of Cycles. The methods are defined via the NODE_SOCKET_API macros in `graph/ node.h`, and are for getting or setting a specific socket's value, as well as querying or modifying the state of its update flag. The setters will check whether the value has changed and tag the socket as modified appropriately. This will let us know how a Node has changed and what to update, which is the first concrete step toward a more granular scene update system. Since the setters will tag the Node sockets as modified when passed different data, this patch also removes the various modified methods on Nodes in favor of Node::is_modified which checks the sockets' update flags status.

Such change brings peak memory usage from 4.1GB to 3.4GB when rendering 01_01_01_D layout scene from the Gooseberry project. Mainly because of freeing memory used by rather huge environment map in the viewport.

Fix #127651: Properly load generated UDIM image tiles in Cycles Since their introduction, generated UDIM images/tiles would not be loaded in Cycles. In relative recent history 72ab6faf5d80a3d added the ability to track which tiles were still marked as being "generated" and unsaved. However, that check was never implemented into the Cycles code. With this PR, these two additional scenarios should now work: - Properly load pixels if all tiles are generated - Properly load pixels if a UDIM image has been loaded from a file and new generated tiles have been added but not saved yet etc. Pull Request: https://projects.blender.org/blender/blender/pulls/127673

Render API/Cycles: Identify Render Passes by their name instead of a type flag Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago. However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images. Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification. Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes. To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available. To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers. To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated.

Fix T93382: Blender still generates subsurface render passes In T93382, the problem was that the Blender-side rendering code was still generating the subsurface passes because the old render pass flags were set, even though Cycles doesn't generate them anymore. After a closer look, it turns out that the entire hardcoded pass creation code can be removed. We already have an Engine API function to query the list of render passes from the engine, so we might as well just call that and create the returned passes. Turns out that Eevee already did this anyways. On the Cycles side, it allows to deduplicate a lot of `BlenderSync::sync_render_passes`. Before, passes were defined in engine.py and in sync.cpp. Now, all passes that engine.py returns are created automatically, so sync.cpp only needs to handle a few special cases. I'm not really concerned about affecting external renderer addons, since they already needed to handle the old "builtin passes" in their Engine API implementation anyways to make them show up in the compositor.

Cycles: Only store per-pixel seed for vertex color baking Currently, during baking each pixel stores a seed input that comes from the Blender side. This is only needed for vertex color baking, however - for regular image baking, we can just as well hash the pixel coordinates. Therefore, we can save some memory (4 byte per pixel) by splitting the seed info out into a separate pass and only storing it when needed.

Fix T93382: Blender still generates subsurface render passes In T93382, the problem was that the Blender-side rendering code was still generating the subsurface passes because the old render pass flags were set, even though Cycles doesn't generate them anymore. After a closer look, it turns out that the entire hardcoded pass creation code can be removed. We already have an Engine API function to query the list of render passes from the engine, so we might as well just call that and create the returned passes. Turns out that Eevee already did this anyways. On the Cycles side, it allows to deduplicate a lot of `BlenderSync::sync_render_passes`. Before, passes were defined in engine.py and in sync.cpp. Now, all passes that engine.py returns are created automatically, so sync.cpp only needs to handle a few special cases. I'm not really concerned about affecting external renderer addons, since they already needed to handle the old "builtin passes" in their Engine API implementation anyways to make them show up in the compositor. So, unless they missed that for like 10 releases, they should not notice any difference. Differential Revision: https://developer.blender.org/D16295

Cycles: code refactor to bake using regular render session and tiles There should be no user visible change from this, except that tile size now affects performance. The goal here is to simplify bake denoising in D3099, letting it reuse more denoising tiles and pass code. A lot of code is now shared with regular rendering, with the two main differences being that we read some render result passes from the bake API when starting to render a tile, and call the bake kernel instead of the path trace kernel. With this kind of design where Cycles asks for tiles from the bake API, it should eventually be easier to reduce memory usage, show tiles as they are baked, or bake multiple passes at once, though there's still quite some work needed for that.

Render API/Cycles: Identify Render Passes by their name instead of a type flag Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago. However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images. Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification. Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes. To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available. To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers. To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated.

Cycles: Implement denoising option for reducing noise in the rendered image This commit contains the first part of the new Cycles denoising option, which filters the resulting image using information gathered during rendering to get rid of noise while preserving visual features as well as possible. To use the option, enable it in the render layer options. The default settings fit a wide range of scenes, but the user can tweak individual settings to control the tradeoff between a noise-free image, image details, and calculation time. Note that the denoiser may still change in the future and that some features are not implemented yet. The most important missing feature is animation denoising, which uses information from multiple frames at once to produce a flicker-free and smoother result. These features will be added in the future. Finally, thanks to all the people who supported this project: - Google (through the GSoC) and Theory Studios for sponsoring the development - The authors of the papers I used for implementing the denoiser (more details on them will be included in the technical docs) - The other Cycles devs for feedback on the code, especially Sergey for mentoring the GSoC project and Brecht for the code review! - And of course the users who helped with testing, reported bugs and things that could and/or should work better!

Cycles: merge of cycles-x branch, a major update to the renderer This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800

Cycles: Added Cryptomatte output. This allows for extra output passes that encode automatic object and material masks for the entire scene. It is an implementation of the Cryptomatte standard as introduced by Psyop. A good future extension would be to add a manifest to the export and to do plenty of testing to ensure that it is fully compatible with other renderers and compositing programs that use Cryptomatte. Internally, it adds the ability for Cycles to have several passes of the same type that are distinguished by their name. Differential Revision: https://developer.blender.org/D3538

Fix T93382: Blender still generates subsurface render passes In T93382, the problem was that the Blender-side rendering code was still generating the subsurface passes because the old render pass flags were set, even though Cycles doesn't generate them anymore. After a closer look, it turns out that the entire hardcoded pass creation code can be removed. We already have an Engine API function to query the list of render passes from the engine, so we might as well just call that and create the returned passes. Turns out that Eevee already did this anyways. On the Cycles side, it allows to deduplicate a lot of `BlenderSync::sync_render_passes`. Before, passes were defined in engine.py and in sync.cpp. Now, all passes that engine.py returns are created automatically, so sync.cpp only needs to handle a few special cases. I'm not really concerned about affecting external renderer addons, since they already needed to handle the old "builtin passes" in their Engine API implementation anyways to make them show up in the compositor. So, unless they missed that for like 10 releases, they should not notice any difference. Differential Revision: https://developer.blender.org/D16295

Cycles: Add support for light groups Light groups are a type of pass that only contains lighting from a subset of light sources. They are created in the View layer, and light sources (lamps, objects with emissive materials and/or the environment) can be assigned to a group. Currently, each light group ends up generating its own version of the Combined pass. In the future, additional types of passes (e.g. shadowcatcher) might be getting their own per-lightgroup versions. The lightgroup creation and assignment is not Cycles-specific, so Eevee or external render engines could make use of it in the future. Note that Lightgroups are identified by their name - therefore, the name of the Lightgroup in the View Layer and the name that's set in an object's settings must match for it to be included. Currently, changing a Lightgroup's name does not update objects - this is planned for the future, along with other features such as denoising for light groups and viewing them in preview renders.

Render API/Cycles: Identify Render Passes by their name instead of a type flag Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago. However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images. Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification. Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes. To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available. To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers. To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated. From a user perspective, nothing should change with this commit. Differential Revision: https://developer.blender.org/D2443 Differential Revision: https://developer.blender.org/D2444

Cycles: Fix missing nested particle systems when instanced multiple times Was only visible when doing command line, since it was happening due to cache-free policy which was aimed to bring memory usage down. The issue is that if object with particle system is used as a nested duplicator multiple times, it will only generate children first time, and after that its caches are freed. After that duplication system can not generate any instances, since the path cache is lost. Now we delay caches free to after all objects are synchronized, which ensures all instances are generated. This will increase a memory peak a bit during object synchronization time, but overall it shouldn't be that bad, since memory footprint after synchronization will stay the same as before this change. The ultimate thing to do here would be to drop the whole dependency graph away, but this will require: - API on engine side, to inform it to drop the dependency graph. - Changes in Cycles report system to NOT use evaluated scene to get scene name (evaluated scene will be gone with dependency graph).

Cycles: Fix missing nested particle systems when instanced multiple times Was only visible when doing command line, since it was happening due to cache-free policy which was aimed to bring memory usage down. The issue is that if object with particle system is used as a nested duplicator multiple times, it will only generate children first time, and after that its caches are freed. After that duplication system can not generate any instances, since the path cache is lost. Now we delay caches free to after all objects are synchronized, which ensures all instances are generated. This will increase a memory peak a bit during object synchronization time, but overall it shouldn't be that bad, since memory footprint after synchronization will stay the same as before this change. The ultimate thing to do here would be to drop the whole dependency graph away, but this will require: - API on engine side, to inform it to drop the dependency graph. - Changes in Cycles report system to NOT use evaluated scene to get scene name (evaluated scene will be gone with dependency graph).

Cycles: Implement texture size limit simplify option Main intention is to give some quick way to control scene's memory usage by clamping textures which are too big. This is really handy on the early production stages when you first create really nice looking hi-res textures and only when it all works and approved start investing time on optimizing your scene. This is a new option in Scene Simplify panel and it acts as following: when texture size is bigger than the given value it'll be scaled down by half for until it fits into given limit. There are various possible improvements, such as: - Use threaded scaling using our own task manager. This is actually one of the main reasons why image resize is manually-implemented instead of using OIIO's resize. Other reason here is that API seems limited to construct 3D texture description easily. - Vectorization of uchar4/float4/half4 textures. - Use something smarter than box filter. Was playing with some other filters, but not sure they are really better: they kind of causes more fuzzy edges. Even with such a TODOs in the code the option is already quite useful.

Add support for tiled images and the UDIM naming scheme This patch contains the work that I did during my week at the Code Quest - adding support for tiled images to Blender. With this patch, images now contain a list of tiles. By default, this just contains one tile, but if the source type is set to Tiled, the user can add additional tiles. When acquiring an ImBuf, the tile to be loaded is specified in the ImageUser. Therefore, code that is not yet aware of tiles will just access the default tile as usual. The filenames of the additional tiles are derived from the original filename according to the UDIM naming scheme - the filename contains an index that is calculated as (1001 + 10*<y coordinate of the tile> + <x coordinate of the tile>), where the x coordinate never goes above 9. Internally, the various tiles are stored in a cache just like sequences. When acquired for the first time, the code will try to load the corresponding file from disk. Alternatively, a new operator can be used to initialize the tile similar to the New Image operator. The following features are supported so far: - Automatic detection and loading of all tiles when opening the first tile (1001) - Saving all tiles - Adding and removing tiles - Filling tiles with generated images - Drawing all tiles in the Image Editor - Viewing a tiled grid even if no image is selected - Rendering tiled images in Eevee - Rendering tiled images in Cycles (in SVM mode) - Automatically skipping loading of unused tiles in Cycles - 2D texture painting (also across tiles) - 3D texture painting (also across tiles, only limitation: individual faces can not cross tile borders) - Assigning custom labels to individual tiles (drawn in the Image Editor instead of the ID) - Different resolutions between tiles There still are some missing features that will be added later (see T72390): - Workbench engine support - Packing/Unpacking support - Baking support - Cycles OSL support - many other Blender features that rely on images Thanks to Brecht for the review and to all who tested the intermediate versions!

Cycles: combined CPU + GPU rendering support. CPU rendering will be restricted to a BVH2, which is not ideal for raytracing performance but can be shared with the GPU. Decoupled volume shading will be disabled to match GPU volume sampling. The number of CPU rendering threads is reduced to leave one core dedicated to each GPU. Viewport rendering will also only use GPU rendering still. So along with the BVH2 usage, perfect scaling should not be expected. Go to User Preferences > System to enable the CPU to render alongside the GPU. Differential Revision: https://developer.blender.org/D2873

Fix #132935: Add sample subset feature to Cycles Cycles has a sample offset feature allowing users to render X samples in a single frame on one device, then the remaining Y samples later or on a different device and combine them back together at the end. However in most situations the result from using this method was different, and usually lower quality than rendering all the samples in one go. This was because Cycles tunes it's random number sequence for the number of samples being rendered. And the random number sequence was being tuned for the wrong number of samples in the case that a user was using the sample offset. This commit fixes this issue by adding a "sample subset" feature. The user specifies the total sample count being rendered across all devices in the existing `Max Samples` parameter, then specifies per device which subset of samples will be rendered (E.g. Render samples 0-1024 out of a 0-2048 range). This commit also contains some additional clean up work inside Cycles related to the area being changed.

Cycles: add denoising settings to the render properties Enabling render and viewport denoising is now both done from the render properties. View layers still can individually be enabled/disabled for denoising and have their own denoising parameters. Note that the denoising engine also affects how denoising data passes are output even if no denoising happens on the render itself, to make the passes compatible with the engine. This includes internal refactoring for how denoising parameters are passed along, trying to avoid code duplication and unclear naming. Ref T76259

Cycles: add denoising settings to the render properties Enabling render and viewport denoising is now both done from the render properties. View layers still can individually be enabled/disabled for denoising and have their own denoising parameters. Note that the denoising engine also affects how denoising data passes are output even if no denoising happens on the render itself, to make the passes compatible with the engine. This includes internal refactoring for how denoising parameters are passed along, trying to avoid code duplication and unclear naming. Ref T76259

Cycles: Add option to change input passes for viewport denoising There are cases where the default input passes of color+albedo do not yield useful results and while this was possible to change that for final frame rendering (in the layer settings), viewport denoising always used a fixed color+albedo. This adds an option to change the input passes for viewport denoising too, so that one can use it in scenes that otherwise wouldn't work well with it.
