When multiple objects are in edit mode, UVs for the objects, except for
the first one (in rendering order) appear corrupted. The corruption is
because the UVs are not evaluated as the compute shader is not bound,
thus we read unitialized memory.
We keep track of the currently bound shader in the GPU context in order
to avoid unnecessary shader switches in case the same shader is used in
consecutive calls. However, the shader used by the OpenSubdiv evaluator
is not part of Blender and therefore not tracked via the GPU context.
When extracting UVs for multiple objects, we only ever run a single
shader (FVar evaluation). However, between the compute calls, we also
call the OpenSubdiv stencil evaluation shader, which uses `glUseProgram`
modifying the current program, outside of our control, which then also
unbinds the Blender compute shader making the compute dispatch fail ("No
active compute shader").
The fact that extracting the UVs for the first rendered object works is
because another (Blender) shader was bound in the GPU context prior to
our binding of our evaluation shader.
To fix this, we remember, in the OpenSubdiv evaluator, the current
program so that it can be reset after the stencil program is done.

The operator assumed it was called on a mesh object, which has
mostly been the case because of lack of support for other object
types, but the new curves object is supported, which is the situation
in the report.

Some of the tools in sculpt mode were still referring to the previously experimental sculpt vertex colors.
They should instead refer to color attributes.

This commits corrects the calculation of the Frame Node label size,
making it independent of the 'Line Width' user preference.
Since `U.dpi` is actually DPI divided by `U.pixelsize` and `U.pixelsize`
is calculated from line-width multiplying by `U.pixelsize` undoes
the connection between line-width and label size.
It now stays the same, regardless of the line-width setting.

These lines were not used now because the handling of copy data has changed.
Assigning the `eval` data can produce unexpected result, especially since everywhere ID_RECALC_TRANSFORM is used, we also do a copy on write. That should take care of `ob->data` for the eval object.
The problem was because the check was done with the total weights of the first element of the array and if this was null or 0, the weights were not duplicated.
As this bug was introduced fixing T97150 due a problem in the weight data, now instead to duplicate all stroke data to create the perimeter for the PDF/SVG, only the points are duplicated because the weights are not needed. This fix the original bug and also reduce the memory used by the export process.
Subdivision did not properly update when evaluating first without and then with
orco coordinates. Now update the subdivision evaluator settings every time, and
reallocate the vertex data buffer when needed.
there is an additional issue in this file where orco coordinates are not
available immediately on the first frame when they should be, and only appear
on the second frame. However that is an old limitation related to the depsgraph
not getting re-evaluated on viewport display mode changes, here we just fix the
crash.
I'm not sure what is causing this. Vertex normals get corrupted
for paint and mask sculpt brushes but not the normal geometric
ones. Since we don't actually need to recalculate normals
here to begin with I've just disabled it. The code now
calls the appropriate node mark update function based on
the sculpt tool.
Previously, when there were multiple curve points at the same or
almost the same position, the computed tangent was unpredictable.
Now, the handling of this case is more explicit, making it more
predictable. In general, when there are duplicate points, it will just use
tangents from neighboring points now.
Also fixes T98209.

The original fix for T97366 was too restrictive and breaks real-world
cases of single-file UDIM textures. See D13297 for an example.
This patch effectively reverts the original fix and instead fixes the
downstream code to accept single-file ranges as necessary.
Note: This means it is very important for users to make use of the
"UDIM detection" option during `image.open` or drag n' drop scenarios in
order to declare their intent when loading their files.

After recent changes to Nishita sky to clamp negative colors, the pixels ended
up a bit brighter which lead to them exceeding the half float max value. The
CUDA float to half function seems to need clamping.
After removing the default 'Home' shortcut for "Frame All", a NDOF (3D
Mouse) default shortcut was still available for the operator. The event
filtering introduced in 4357fb63db was missing the NDOF filtering
logic. So while the context menu correctly found the NDOF keymap item,
its actual shortcut change/removal code incorrectly filtered out the
NDOF keymap items and thus failed to find the item.
This is a regression caused by a230445cae.
The internal cause of the issue was that the synchronization component
was no longer tagged as visible (and hence not evaluated) as it not
connected to any directly visible IDs.
Changed the logic in a way that if any component of an ID is evaluated
the synchronization component will be evaluated as well.
The naming of the flag in the component node is a bit confusing, but
for the simplicity of the change for the upcoming release left it
unchanged.
`BKE_id_delete` should only check for consistency of user count with
regards to the tags and flags of the ID, not 'protect' nor even warn in
case a 'fake user' ID is deleted (such higher-level checks are to be
handled by higher-level code).
Also replace the assert + debug print by a CLOG error, this avoids
'assert crash' while still failing tests, and always producing a useful
message.
Fixes T98374 and T98260.
Callbacks used in the gizmo operator template don't support updating
while being dragged, set the EXCLUDE_MODAL flag so the offsets
aren't accumulated. Also fix the offset being applied twice to the
move gizmo.
A global variable was mistakenly used here which would accumulate the
vertex attributes (leading to an assertion failure after a while), use
the wrong number of components depending on the attribute data type,
among other issues.
Faces, edges, and vertices are still shown when GPU subdivision is
actived. This is because the related edit mode flags were ignored by the
subdivision code.
The flags are now passed to the various compute shaders mostly as part of
the extra coarse data, also used for e.g. selection. For loose edges, a
temporary buffer is created when extracting them. Loose vertices are
already taken into account as it reuses the routines for coarse mesh
extraction, although `MeshRenderData.use_hide` was not initialized,
which is fixed now.
When appending an already linked data, `BKE_blendfile_append` would not
properly substitute the `item->new_id` pointer of link/append context
items with the local duplicate of the linked ID.
This would cause drag'n'drop of assets to work incorrectly in some
cases. Fixes part of T95706 and T97320.
Regression in [0] which removed the call to BVH-tree recalculation
before calculating the selection.
Instead of recalculating the BVH-tree, postpone recalculating mesh data
until after the selection has been calculated.

Added in [0] but isn't needed as all needed variables are in the
ViewContext. Avoid passing in the context is it makes debugging
issues with MESH_OT_knife_project more difficult to investigate since
it's possible values written to the ViewContext are ignored.

When no image user is known the last used frame of the image is used to
read a frame. When partial updating an image there is always an image user
that would use a zerod out image user, meaning the frame number is set to 0
when using the clone tool.
This fix syncs the frame with the last used frame of the image to ensure
that the buffer exists. There is a bailout in the overlay_edit_uv.c.
8f79fa9c67 was an attempt to fix this already, but it didn't quite
work. Problem was that the tooltip was messing with the drop-box and
operator properties, setting the name property for its own internal
logic. This name property would then be used rather than the session
UUID to query the material, which gave the wrong material (linking can
result in multiple IDs of the same type with the same name). A followup
commit will further sanitize this.
More and more of the drop operations are being switched to use the ID's
session UUID rather than the name, but the cleanup after a drop operator
was cancelled assumed they would set the name. They will now first
attempt to use the session UUID and fallback to the name if needed.
Add notifier such that the Motion Paths panel in the Object Properties tab
gets redrawn, after using the Create Motion Path button.
The reason it didn't update was that the button actually triggers a popup,
and then executes in the context of that popup. It now actually emits a
`ND_DRAW_ANIMVIZ` notifier, and ensures that the panel redraws on that.
It is a know issue that split normals aren't supported when using high
quality normals in the viewport. Some AMD platforms were pushed to use
high quality normals to work around a driver bug where 1010102 texture
formats `GL_INT_2_10_10_10_REV` wasn't uploaded to the GPU.
This change will remove commonly used polaris platforms from the
work-around. This has been tested with a RX480 against the latest AMD
whql drivers (22.5.1). Users need to ensure that they use the latest
drivers that are available on their platform.
Although this change doesn't fix the underlying issue to support edit
normals when high quality normals are enabled. It will not force that
common platforms cannot use a feature as their platform is forced into
using a work-around.
Since rBb47c5505aa37, Batchs containing GPUIndexBuf initialized via
a PyObject with buffer protocol no longer work.
This was because of an unsafe optimization in the GPUIndexBuf module
for Python.
So remove this micro-optimization.
