Missing null check when retrieving face sets for multires automasking.
Caused by b5f7af31d6d474c3b455b.
|
|
|
|
The stereo saving code that combines two image buffers into one did not work
correctly when the number of channels is not equal to 4.
|
|
PBVH draw was invalidating the draw cache even
when disabled (e.g. if modifiers exist).
|
|
The members were named after .mtl file syntax ("d") instead of their
meaning ("alpha"). In preparation for extending OBJ code for more
PBR parameters support, rename them for clarity. No functionality
changes, just a pure rename.
|
|
Also include a small cleanup to the previous commit missed from review.

Always swap values when restoring sculpt undo data.

corresponding data layers and using their values for computations.
Avoiding that should increase performance in many operations that
would otherwise have to read, write, or propagate these values.
It also means decreased memory usage-- not just for sculpt mode
but for any mesh that was in sculpt mode. Previously the mask, face set,
and hide status layers were *always* allocated by sculpt mode.
Here are a few basic tests when masking and face sets are not used:
| Test | Before | After |
| Subsurf Modifier | 148 ms | 126 ms |
| Sculpt Overlay Extraction | 24 ms every redraw | 0 ms |
| Memory usage | 252 MB | 236 MB |
I wouldn't expect any difference when they are used though.
The code changes are mostly just making sculpt features safe for when
the layers aren't stored, and some changes to the conversion to and
from the hide layers. Use of the ".hide_poly" attribute replaces testing
whether face sets are negative in many places.

sculpt_update_object now auto-creates a CD_MDISPS layer
if missing. Note that it is possible for the depsgraph
to provide a multires ccg context without a CD_MDISPS.
This causes a PBVH_GRIDS pbvh to be built instead of
falling back to PBVH_FACES, which is why this bug happens
(of course falling back to PBVH_FACES would still be a bug).
|
|
We don't need to be on the main thread to destroy the context.
|
|
These changes were implemented by Sonny Campbell.
Fixed the first issue by freeing the operator customdata when the import
is cancelled.
Fixed the second issue by using a character array instead of allocating
new memory for the prim_path_mask.

When resizing mesh and curves attribute storage, avoid initializing the
new memory for basic types. Also, avoid skipping "no free" layers; all
layers should be reallocated to the new size since they may be accessed.
The semantics introduced in 25237d2625078c6d1 are essential for this
change, because otherwise we don't have a way to construct non-trivial
types in the new memory.
In a basic test of the extrude node, I observed a performance
improvement of about 30%, from 55ms to 42ms.

Generally we don't want to do per-element operations on these spans
because of the overhead of the runtime type system, but these operations
on the whole span avoid ugly pointer arithmetic in other areas.
|
|
Previously, the only versions of attribute access that gave a span would
also add the attribute when it doesn't exist, which isn't always wanted.

The bug was contained in BKE/intern/nla.c, where the wrong macro was
used as the minimum frame value. Instead of `MINAFRAMEF`, `MINFRAMEF`
was used (the former is around -10k, the latter is 0, both fp32).

After 2c23b4e0bff0 the meaning of PYTHON_LIBPATH changed.

Starting from GLibC 2.34, deprecated `__malloc_hook` & co. have been
removed from headers, while still present in the shared library itself.
This means that it is no more possible to build Blender with USD 22.03
on recent linux systems.
While USD 22.08 has a fix to this issue, it is unlikely to be upgraded
for Blender 3.4, and definitely not for Blender 3.3.
This commit ensures Blender can build with USD 22.03 and glibc >= 2.34.

The operator was not checking the status of the
Autokey button.

Although view layers aren't ID, they do support custom properties,
so not providing the UI to access them seems to be a simple oversight.

special_aftertrans_update would always use TransInfo values (not
the values_final -- we need the final values to follow numinput, snapping,
etc).

Provide reasonable defaults for UV unwrap for triangles with zero area:
* Three vertices are arranged in a line.
* Two vertices are at the same 3D location.
* All three vertices are at the same 3D location.
Change fixes quads / ngons which have triangulations with zero area.
Change fixes both "Angle Based" method and "Conformal" method.

Also use a larger buffer to account for the unlikely case of the
buffer not being big enough for the appended directories.

Also note that leading slashes are kept in the doc-string.

An edge can be marked BM_ELEM_SEAM, which means the UV co-ordinates
on either side of the edge are actually independent, even if they
happen to currently have the same value.
This commit optionally add support for UV Seams when computing islands.
Affects UV sculpt tools, individual origins, UV stitch and changing
UV selection modes etc.
Required for upcoming packing refactor which requires seam support
when computing islands.

Caused by 21f2bacad977d3fd8 which copies a few more values to
the original meshes from the "nomain" meshes. The "nomain" meshes
created from the originals need to copy some values as well.

Related to {D15885} that requires scene parameter
to be added in many places. To speed up the review process
the adding of the scene parameter was added in a separate
patch.

This operator allows to set the start point for any cyclic stroke.
This is very handy to fit interpolation issues or
use thickness modifier.
Note: There is small change in this commit to fix
a typo error in the name of the operator.

Build against Python from precompiled libraries by default, instead of
requiring framework from python.org package install. The resulting bpy module
can still be used with any Python install of the same version.
Use the same CMake find module as Linux. This simplifies code, and makes it
possible to manually set PYTHON_* variables in CMake configuration.
Remove WITH_PYTHON_FRAMEWORK option for regular Blender build, as this doesn't
work well due to missing required Python packages. Advanced users can still
set PYTHON_ROOT_DIR=/Library/Frameworks/Python.framework/Versions/3.10 for
the same result.

Although unlikely, the result of BKE_appdir_folder_id_create may be NULL.

Checking if a property exists only makes sense for generic callbacks

This attribute is still read and written in the legacy format which
puts it inside of `MPoly`. Missed in f1c0249f34c4171ec.

This shader is required by some addons that need to modulate the alpha of images.

This has been a pain, newer OpenVDB forcefully trying to use more recent
system TBB (oneTBB) instead of the one built by this script.
Also include a few minor unrelated fixes.
