This is not something we support currently. Before, the simulation would just
not do anything. Now there is an error message.
In theory, a limited version of that could be supported eventually but it does
not have high priority currently. The tricky aspect of supporting this is that
each simulation has a cache, can be baked etc and we need a persistent identify
for those. That's not possible if simulations can be added and removed
dynamically all the time.

After exposing options as inputs, the following gizmos may be drawn but
have no effect when tweaked:
- Sun beams
- Ellipse mask
- Box mask
- Split
This patch hides the gizmo when the relevant node inputs are linked

This adds a new function `set_vertex_weights` to the `GreasePencilDrawing`.
Given an existing vertex group, this function writes the given weights to the
provided point indices.
Example code for GP Stroke:
```Py
import bpy
ob = bpy.context.active_object
# Add a vertex group
ob.vertex_groups.new(name="Group")
# Get the drawing
frame = ob.data.layers.active.current_frame()
drawing = frame.drawing
# Set the vertex weights of points at index 0, 5, 10, and 15
drawing.set_vertex_weights("Group", [0, 5, 10, 15], [0.1, 0.2, 0.5, 1.0], assign_mode='ADD')
```

It appears that previously, assembly was straight up disabled for all ARM64 platforms in x264 - this re-enables it.
This also updates the version of FFmpeg to 7.1.1. I updated the patch files so that they would cleanly apply to 7.1.1.
For Windows ARM64, it also switches both of these libraries to use the copy of LLVM we build as part of the deps, instead of MSVC - this gives a small performance increase. To do this for x264, I added a small patch taken from VCPKG - this should be harmless to other platforms.
With all these changes, I was able to get a ~20-30% perf improvement in video transcoding in the sequence editor.

`IMB_load_image_from_file_descriptor` use mmap to read images, and mmap
sometimes can have erroreous state llike accessing a file from network
drives. This patch tries to handle these exceptions like `BLI_mmap_read`
on Win32 (On unix the `sigbus_handler` will be called instead).

During rendering when main thread is blocked or all screens are minimized the
garbage collection will not happen resulting in crashes as resources are not freed.
A better solution would be to do garbage collection in a separate thread but that requires a
ref counting system. The specifics of such a system is still unclear.
A possible solution for a Vulkan specific ref counting is to store the ref counts in the
resource tracker. That would only handle images and buffers, but it would solve the most
resource hungry issues.

This patch uses 2D and 4D sockets for relevant node sockets in the
compositor. This only on the UI side, internally, some of the sockets
still store 3D data, which will be handled in a later patch in the 5.0
release.

Meshes with millions of vertices could freeze when storing
edit-mode undo steps. This occurred when de-duplicating boolean arrays
(typically selection & hidden data).
This problem occurred after v3.3 because vert/edge/face flags were
moved into their own boolean custom-data layers.
Resolve using run-length encoding, used to encode all boolean
custom-data layers before adding them to the BArrayStore.
The overall speedup depends on the order of elements in the mesh
as well as the previous state of the mesh used for comparison.
Testing box selection with subdivided cubes (3.9 million vertices)
shows a speedup from an around between 8..16 seconds to ~0.025 seconds.
Even though this ran in a background thread, adding undo steps
waits for the previous step to finish which could freeze.
Tweaks to BLI_array_store such as increasing the block-size used by
edit-mesh undo and increasing length of hashed data helped but didn't
resolve the issue, see: !138975.
See code-comments for details.
Add RLE encoding/decoding functions for byte arrays for the purpose
of pre-processing arrays with large spans of (mostly) uniform values
before storing them in a BArrayState.
Part of a fix for #136737.
The menu item for Knife tool and what is bound to the "K" differ by
some properties so it does not show the shortcut on the menu. Those
properties are all defaults, so this PR just removes those from the
keymap. Everything works as now, but it shows the shortcut.

Previously, it was possible for the number of stored columns per table to grow
unbounded. While this likely isn't a problem in practice in most cases, one can
imagine cases where people temporarily have thousands of attributes when are
then never used again. We shouldn't have to store any data for these columns
forever.
This patch adds some simple garbage collection mechanism that keeps the number
of stored unavailable columns per spreadsheet table below a certain threshold
(50 currently). Least recently used columns are removed first.

This started with investigating a render issue that appears to be caused by
GCC 15. From what I can tell, it was caused by
`*viewplane = (*viewplane) * bcam->zoom;`.
I'm not entirely sure what the root cause is (potentially pointer aliasing?),
but the restructured code works fine now.

It was intended that pointers instancers would be skipped if they were
marked as invisible. However, we didn't account for the case of an
instancer using the "inherits" visibility but one of its ancestors in
the hierarchy being invisible.
Now these instancers will also be excluded. This is done by checking for
purpose and visibility earlier and halting the recursive traversal as
soon as we find a prim which doesn't meet the criteria.

Videos that are higher bit depth than 8 bit are decoded into floating
point formats (so anything that uses 10/12 bits or HDR). Speedup:
- Multi-thread GBRA planar -> RGBA interleaved conversion.
- If video is rotated, do the rotation step while doing the above
conversion directly, instead of a separate rotation afterwards. Cuts
down on memory bandwidth usage.
Playing back two 1920x1080 video tracks, where both are rotated and
H.265 10 bit HDR, on my PC (Ryzen 5950X), average playback frame time
goes 47ms -> 32ms (so 21FPS -> 31FPS)

Previously, columns were removed from a table in the spreadsheet if they are not
available anymore. This also meant that their position and width was lost. When
the same column became available again, it was inserted at the end.
This patch makes it so that each table also remembers the columns that are not
available currently (and flags them accordingly). This way, the position and
width can be restored once the data becomes available again.

Do it in make update tight after adding the remote. For some reason the
searchall mechanism does not work reliably immediately after checkout.
Fixes part of #139328.
On selected platforms there were some validation errors. It was caused by
platforms that returned a different number of swapchain images then were
requested. In that case the semaphores can get out of sync.
Current mechanism isn't future proof as the max number of images are
statically defined.
For this change the present semaphores is also separated from the frames
to better support out of order swapchain images.

This patch turns the Blur node options to inputs.
Size is now a 2D vector and replaces the Size X and Y option. Bokeh was
renamed to Separable to reflect its actual function. Relative was
removed in favor of the newly added Relative To Pixel node workflow.
There is a slight difference in variable size blurring due to float vs
integer computations, so two tests were updated.
Reference #137223.

This removes redundant labels from various input nodes like the Value, Integer
and Object node.
Design wise, this is mostly straight forward except for two aspects:
* Some input nodes some have a gizmo icon. In this case I just added the gizmo
icon on the same row.
* The checkbox in the Boolean input node should probably still have a label, so
I kept that.
Implementation wise this adds a new function to socket declarations that allows
us to override the draw behavior of individual sockets per node.

With OIDN extending its support for new AMD devices, Blender source
code needs to be updated accordingly to reflect these OIDN changes
in the hipSupportsDeviceOIDN function. This function represents
OIDN support on AMD, allowing Blender to know this information
beforehand and avoid unnecessary errors due to attempt to denoise
on unsupported devices, as it was before the introduction of
the hipSupportsDeviceOIDN function.

This patch adds support for 2D and 4D vector sockets. The default value
structure for vectors was extended to include a new dimensions input,
which can be 2, 3, or 4. The default value was also extended to be a
float4, but only some of its components might be used depending on the
dimensions members.
Each vector subtype now has three variants ending with 2D or 4D as a
prefix depending on its dimensions, and the 2D/4D prefix was taken into
account for the socket type RNA enum functions.
All node systems currently always treat the vectors as 3D, but support
for it in the compositor will shortly follow in another patch.
Depends on #138805.

This is adding a hard error for backends do that do not supports it.
Even without this, the backend would return a nullptr. But the error
message in this case was just "see console for more details" without
any additional detail. Which was confusing.
Unlike OpenGL and Metal, this handle is not shared, but rather Cycles
has to take ownership of it. This required a fair amount of refactoring
to ensure the handle is closed, ownership is properly transferred, and
the handle is recreated once when the pixel buffer is modified.
The cryptomatte textures where optimized for samplers, but could trigger
UB as they are also used with load/store. This PR will change the
dynamic data type of the cryptomatte to always use RGBA32F.

The `immVertex2i` calls in `drawWalkPixel` will now cause an assert in
`immAttr2i` after 617858e453 because the component types are more

This patch adds a new Dimensions output to the Image Info node. Contrary
to the Resolution output, the Dimensions output takes transformations
into account. So an image of resolution 512x512 that is scaled up by 2
would have a Resolution of 512x512 but a Dimensions of 1024x1024.
