Cache files are currently loaded via the Manta Python API. With very big caches this can slow down the viewport playback. Especially smoke simulations, which just load grids and no meshes, can suffer from this. This fix solves this problem by directly loading the cache files from disk (no Python). This fix has been in the works for some time. The developer of this patch is ready to handle any potential fall-out of this patch quickly.
BKE_nurb_type_convert now takes r_err_msg and is more specific in the

This is a small optimization that makes sure the adaptive domain only considers active inflow objects. Ones with disabled fluid flow are skipped and thus the adaptive domain will not try to cover them.
Added sanity check in the flow / obstacle object loops that check if the modifier data is valid. Ideally this should not be needed. However, in remove_particle_systems_from_object() the fluid modifier can get freed. It is not yet clear whether the modifier free call is really needed or not.
Font duplicator was not outputing dupli-objects using evaluated object
pointers, leading to crash because original object are not supposed to
be drawable.
Usual issue from those dear Bone pointers in pose data...
Note that this is more like minimal-risk, quick fix, it's nothing like
'nice to have' code. Think proper solution would be to refactor handling
of those kind of 'caches' to ensure they are valid/up-to-date in a much
easier way, at the very least.
Ideal solution being to get fully rid of those horrors, of course, but
let's not dream here. ;)
This commit cleans up the flow emission code (i.e. the code that determines where flow is generated). It also addresses an issue with initial velocities.
Related issues (that might be fixed through this commit) are: T73422, T72949
- Initial velocities are no longer influenced by surface distance value.
- Added optimizations for different flow types (e.g. skip part of loop for liquid flow objects).
- Comments style cleanup and removed old todos.
This code is currently not in use and so removing it based on the YAGNI principle. If there really is need for a high-res emission loop it could be easily added again. However, I believe for the smoke noise it is sufficient to upscale the base emission map. A high-res emission map can easily be achieved by increasing the base resolution. Note also that in the new fluid system base loop and noise loop are decoupled making the need for a high-res emission loop even more unneccessary.
Need to also offset markers in BKE_sequence_base_shuffle_time().
Also clarify/correct related comments.

This was due to the fact the drawing code was expecting the editpoints
to be equaly spaced. Reuse the code in particle.c to output the select
mask in red color channel of the particle (which is unused in new code).
The dependency graph has to know whether a driver must be re-evaluated
every frame due to a dependency on the current frame number. For python
drivers it was using a heuristic based on searching for certain sub-
strings in the expression, notably including '('.
When the expression is actually evaluated using Python, this can't be
easily improved; however if the Simple Expression evaluator is used,
this check can be done precisely by accessing the parsed data.

The full name was "Topology Slide/Relax", but it didn't fit in the
toolbar UI. This was causing some problems:
- The mesh filter that does the same thing is called "Relax"
- We may want to add a "Topology Brush" tool in the future that is more
oriented to retopology task (like creating strips of quads), so by doing
this we avoid having two tools with the same name in the UI.

This is a more correct fix to the issue Brecht was fixing in D6600.
While the fix in that patch worked fine for linking it broke ASAN
runtime under some circumstances.
For example, `make full debug developer` would compile, but trying
to start blender will cause assert failure in ASAN (related on check
that ASAN is not running already).
Top-level idea: leave it to CMake to keep track of dependency graph.
The root of the issue comes to the fact that target like "blender" is
configured to use a lot of static libraries coming from Blender sources
and to use external static libraries. There is nothing which ensures
order between blender's and external libraries. Only order of blender
libraries is guaranteed.
It was possible that due to a cycle or other circumstances some of
blender libraries would have been passed to linker after libraries
it uses, causing linker errors.
For example, this order will likely fail:
libbf_blenfont.a libfreetype6.a libbf_blenfont.a
This change makes it so blender libraries are explicitly provided
their dependencies to an external libraries, which allows CMake to
ensure they are always linked against them.
General rule here: if bf_foo depends on an external library it is
to be provided to LIBS for bf_foo.
For example, if bf_blenkernel depends on opensubdiv then LIBS in
blenkernel's CMakeLists.txt is to include OPENSUBDIB_LIBRARIES.
The change is made based on searching for used include folders
such as OPENSUBDIV_INCLUDE_DIRS and adding corresponding libraries
to LIBS ion that CMakeLists.txt. Transitive dependencies are not
simplified by this approach, but I am not aware of any downside of
this: CMake should be smart enough to simplify them on its side.
And even if not, this shouldn't affect linking time.
Benefit of not relying on transitive dependencies is that build
system is more robust towards future changes. For example, if
bf_intern_opensubiv is no longer depends on OPENSUBDIV_LIBRARIES
and all such code is moved to bf_blenkernel this will not break
linking.
The not-so-trivial part is change to blender_add_lib (and its
version in Cycles). The complexity is caused by libraries being
provided as a single list argument which doesn't allow to use
different release and debug libraries on Windows. The idea is:
- Have every library prefixed as "optimized" or "debug" if
separation is needed (non-prefixed libraries will be considered
"generic").
- Loop through libraries passed to function and do simple parsing
which will look for "optimized" and "debug" words and specify
following library to corresponding category.
This isn't something particularly great. Alternative would be to
use target_link_libraries() directly, which sounds like more code
but which is more explicit and allows to have more flexibility
and control comparing to wrapper approach.
Tested the following configurations on Linux, macOS and Windows:
- make full debug developer
- make full release developer
- make lite debug developer
- make lite release developer
NOTE: Linux libraries needs to be compiled with D6641 applied,
otherwise, depending on configuration, it's possible to run into
duplicated zlib symbols error.

Waveform is freed in `sound_load_audio()` when sound length is `queried by BKE_sound_info_get()`.
Add argument free_waveform, so `BKE_sound_info_get()` can skip waveform freeing, as it is not expected to alter sound.

Refactor code to use `eSpaceSeq_Proxy_RenderSize` or corresponding `IMB_Proxy_Size`
enum items directly.
`SEQ_PROXY_RENDER_SIZE_100` has assigned value 99 to distinguish from `SEQ_PROXY_RENDER_SIZE_FULL`.
This caused error in image size calculation and because of that image had to be scaled.

This data is only used to get current time/frame value, which is never
mandatory to add a modifier.
Needed by incoming fix to support particles modifiers in liboverrides.
The `give_parvert()` function was only considering the mesh's original
vertex indices when the parent vertex index was valid for the evaluated
mesh. However, when using the Mask modifier the evaluated mesh can have
less vertices but still have the parent vertex.
Since the `if (nr < numVertex)` condition wasn't used to prevent any
out-of-bounds access, and seems just an incorrect optimisation, it could
be removed.
This would happen if a tile is found on disk, painting would actually
request that tile (because corresponding uvs were in that range), but
that tile was not added in blenders list of tiles in that Image.
Need to also check tile in `image_quick_test` (regardless of iuser
having passed).
thx @lukasstockner97 for additional input!

We can't use the fast path when the mesh is used by mulitple objects and so
slower sculpting is expected then. But fake users should not affect this. This
also fixes the same type of error in a few other areas.
Cache file loading for mesh and particle files now works through the direct update_structures functions. The final cache mode now also only bakes the most essential files and is therefore not resumable anymore.
When computing the roll value coming from the handle bone, the code
was using some strange unexplained math. It probably works fine when
the difference with the 'zero roll' orientation is pure twist, like
is the case when called from mat3_to_vec_roll. However, it appears
to break when significant swing is involved.
The issue is fixed by using the proper Swing+Twist decomposition
utility function that was added in a recent version for drivers.
Once again, am not exactly sure why that was working before, and not
anymore - but in any case, doing that kind of update here is not only
useless (since we have to do it at the end of the whole
collections/objects duplication and remapping anyway), it is also rather
dangerous, as collections are currently in rather invalid states at that
point of the code...
Note that in ideal world, `BKE_main_collection_sync()` & co would be
lazy (setting only a flag, then code actually needing this to be valid
again should call some sort of `BKE_main_collection_sync_ensure()`).
Then we would not have to worry about such things (and we'd get nice
performance improvements in some cases, also in main remapping code,
etc.).
Food for some refactoring, some day...
Both actual Collection datablocks and the horrible master collection
should share the same code (there were already some differences,
although probably not critical, but some callbacks from
scene->master_collection did not have the 'not self' flag...).
The last handle wasn't corrected, also, there is no reason
to flip the handles while sorting (checking the same handles many times)
move this into it's own loop.
Based on @fclem's suggestion in D6421, this commit implements support for
storing all tiles of a UDIM texture in a single 2D array texture on the GPU.
Previously, Eevee was binding one OpenGL texture per tile, quickly running
into hardware limits with nontrivial UDIM texture sets.
Workbench meanwhile had no UDIM support at all, as reusing the per-tile
approach would require splitting the mesh by tile as well as texture.
With this commit, both Workbench as well as Eevee now support huge numbers
of tiles, with the eventual limits being GPU memory and ultimately
GL_MAX_ARRAY_TEXTURE_LAYERS, which tends to be in the 1000s on modern GPUs.
Initially my plan was to have one array texture per unique size, but managing
the different textures and keeping everything consistent ended up being way
too complex.
Therefore, we now use a simpler version that allocates a texture that
is large enough to fit the largest tile and then packs all tiles into as many
layers as necessary.
As a result, each UDIM texture only binds two textures (one for the actual
images, one for metadata) regardless of how many tiles are used.
Note that this rolls back per-tile GPUTextures, meaning that we again have
per-Image GPUTextures like we did before the original UDIM commit,
but now with four instead of two types.
