This option allows posing meshes with different disconnected elements
using the Pose Brush.
This is achieved by doing the following:
- Creating an ID per vertex that stores the connected component of that vertex.
- By using those IDs, one fake topology connection is created per vertex to the nearest vertex in a different ID. The maximum distance to create that connection is determined by the "Max Element Distance" property. These fake connectivity neighbors are used in the Sculpt API functions iterators, so all the algorithms of the Pose Brush can run without modifications as if everything was part of the same mesh.
In order to make this work, the "Connected only" property of the Pose Brush needs to be disabled. This will add an extra performance cost to the Pose Brush and its preview. To achieve optimal results, max element distance should be as low as possible.

IDs like embedded ones (master collections, root node trees) cannot be
linked, and thus cannot be real override themselves.
Since they are managed by their owner ID, that one will also have the
overrides for their locally edited properties.
We still need a way to mark them as overridden though, for various UI
and override-internal purposes, this is done using a new ID flag.
Note that since Shae Keys are not linkable, and their pointers are not
editable in RNA, they are also considered as embedded from override
point of view.

This is cleaner, but also crucial to avoid weird issues when behaviors
of those checks are modified...

The shortcuts act on the modifier with its panel under the mouse.
The following shortcuts are enabled by default:
- Remove modifier: X, Delete
- Apply modifier: Ctrl A
- Duplicate modifier: Shift D
More shortcuts can be added in the keymap.
Each panel can now store a custom data RNA pointer, and a new
function is added to get the custom data for the panel under the
cursor. This custom data could be used to refactor the "List Panel
System" to generalize it and integrate it further with RNA.
The same functionality will be added in further commits where it
applies to constraints, grease pencil modifiers, and effects.

Also add additional validation to ensure the denoiser is supported before
trying to use it.

|

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.

Sculpt Vertex Colors is a painting system that runs inside sculpt mode, reusing all its tools and optimizations. This provides much better performance, easier to maintain code and more advanced features (new brush engine, filters, symmetry options, masks and face sets compatibility...). This is also the initial step for future features like vertex painting in Multires and brushes that can sculpt and paint at the same time.
This commit includes:
- SCULPT_UNDO_COLOR for undo support in sculpt mode
- SCULPT_UPDATE_COLOR and PBVH flags and rendering
- Sculpt Color API functions
- Sculpt capability for sculpt tools (only enabled in the Paint Brush for now)
- Rendering support in workbench (default to Sculpt Vertex Colors except in Vertex Paint)
- Conversion operator between MPropCol (Sculpt Vertex Colors) and MLoopCol (Vertex Paint)
- Remesher reprojection in the Voxel Remehser
- Paint Brush and Smear Brush with color smoothing in alt-smooth mode
- Parameters for the new brush engine (density, opacity, flow, wet paint mixing, tip scale) implemented in Sculpt Vertex Colors
- Color Filter
- Color picker (uses S shortcut, replaces smooth)
- Color selector in the top bar

This revisit the render pipeline to support time slicing for better motion
blur.
We support accumulation with or without the Post-process motion blur.
If using the post-process, we reuse last step next motion data to avoid
another scene reevaluation.
This also adds support for hair motion blur which is handled in a similar
way as mesh motion blur.
The total number of samples is distributed evenly accross all timesteps to
avoid sampling weighting issues. For this reason, the sample count is
(internally) rounded up to the next multiple of the step count.
Only FX Motion BLur: {F8632258}
FX Motion Blur + 4 time steps: {F8632260}
FX Motion Blur + 32 time steps: {F8632261}

This will allow the easier addition of a constant radius mode in the
future and some changes in the UI to mirror the recent similar change
from "Only Vertices" to the "Affect" enum.

Using 'name' for the full path of a file reads badly,
especially when id.name is used in related code.
|
|
Make it clear that this is the absolute path,
allow the 'name' to be renamed to 'filepath'.
Rename is safe since this is only for run-time.

This patch implements the list panel system D7490 for grease pencil
shader effects. It also moves their drawing to a callback in
ShaderFxTypeInfo in line with the extensible architecture refactoring
goal T75724.
The implementation is basically exactly the same as for the modifier
patch (9b099c86123fc82).
Thanks to Matias Mendiola (@mendio) for helping to develop the layout
changes.

This patch implements the list panel system D7490 for constraints.
In this case the panels are still defined in Python.
The layouts are also updated to use subpanels and the a more organized
single column layout. There may be more tweaks necessary for the
layouts.

This adds object motion blur vectors for EEVEE as well as better noise
reduction for it.
For TAA reprojection we just compute the motion vector on the fly based on
camera motion and depth buffer. This makes possible to store another motion
vector only for the blurring which is not useful for TAA history fetching.
Motion Data is saved per object & per geometry if using deformation blur.
We support deformation motion blur by saving previous VBO and modifying the
actual GPUBatch for the geometry to include theses VBOs.
We store Previous and Next frame motion in the same motion vector buffer
(RG for prev and BA for next). This makes non linear motion blur (like
rotating objects) less prone to outward/inward blur.
We also improve the motion blur post process to expand outside the objects
border. We use a tile base approach and the max size of the blur is set via
a new render setting.
We use a background reconstruction method that needs another setting
(Background Separation).
Sampling is done using a fixed 8 dithered samples per direction. The final
render samples will clear the noise like other stochastic effects.
One caveat is that hair particles are not yet supported. Support will
come in another patch.

Currently all force effectors can only act on cloth when the force is
perpendicular to the surface. This makes sense for wind, but not for
other forces; and the user may want even wind to have some friction.
This changes effector code to output two force vectors - although
you of course can pass the same pointer for both. The force is split
between the two outputs based on a new per-effector setting.

This removes G_FILE_HISTORY, G_FILE_SAVE_COPY & G_FILE_USERPREFS.
Using file-flags made logic harder to follow since it's not so clear
which flags are expected to be in G.fileflags & which are meant to be
set and passed as arguments, these are shared between read & write
functions too.
Add BlendFileWriteParams so options which don't need to be stored
aren't mixed up with flags that are stored for reuse.

When "Relative Remap" option was added, the intention was only to remap
paths that were already relative. However it remapped all paths.
This was reported as T62612 and fixed recently,
however some Python script authors depended on the old behavior.
For users, it's reasonable to use the existing operators to make paths
absolute/relative. For scripts however it's useful to be able to write
out individual data-blocks with the ability to make all paths relative.
Now `bpy.data.libraries.write()` takes a path_remap argument which can
be `NONE/RELATIVE/RELATIVE_ALL/ABSOLUTE` allowing the script author to
choose how paths are handled when writing out data-blocks.
Addresses T77768.

Prelimenary step to fix T77460.
Not sure how or when that thing was done, but since that call walks
around collections relationships, it's an utterly critical violation of
liblinking principles (code here should never, ever 'get outside' of its
own ID scope).
This was wroking so far only because code called through this function
(`BKE_collection_parent_relations_rebuild`) was only following parents
pointers (in `BKE_collection_find_cycle()`), which would be either valid
or non-existent.
But next commit is going to change that to also check collection's
objects instancing of other collections.

When a fluid is put under influence of gravity or acceleration, it
forms an internal pressure gradient, which causes observable effects
like buoyancy. Since now cloth has support for simulating pressure
changes caused by fluid compression or expansion, it makes sense to
also support the effects of gravity.
This is intended for better simulation of objects filled or
surrounded by fluids, especially when constrained by collisions
or pinned vertices, and should result in more realistic shapes.
Obviously, this doesn't actually simulate fluid dynamics; instead
it is assumed that the fluid immediately adapts to changes in the
shape or acceleration of the object without friction or turbulence,
and instantly reaches a new static equilibrium.
