Cycles uses the "split faces" mesh function to support sharp edges
and auto-smooth. However, 75ad8da1ea updated that
function to ignore the edges that are explicitly tagged as sharp and
only use the edge angle. Fix by taking the attribute into account too.
The custom data layer mappings from dfacaf4f40 were created
*before* the BMesh shape key layers were added, invalidating the BMesh
data offsets they stored. Fix by creating the mappings after all layers
have been created.
Clean up logic to make it more clear and formalize the way to choose
fixed node data type based on operation. This make possible to more
easily fix wrong node data type for color type and less than ops.

When appending assets it often isn't expected for the asset tags and

disable appending the asset data, exposing existing internal options.
When the users click the "Mark as Asset" with the mouse hover the fake

Pull Request #104626
Code to set the dragging data for a button was mostly duplicated, they
share it now. The followup commit also needs an easy way to reuse the
logic, which is possible now.
No longer use the existance of an image pointer inside the button, or
the the type of a button to decide if the entire button should be
draggable, or only its icon. This was rather sneaky, undocumented
behavior. Instead make this a proper option in the public UI API, and
enable it by default in specific cases to match the previous behavior.
This at least makes the behavior known and controllable in the API, and
not something that's just "secretly" done deep down in the button
handling code. I'd argue we should just use the entire button width by
default for dragging, but that would be a bigger change.
After the removal of the "normal" attribute providers, we no longer

The "normal" was added before fields existed because we needed a
way to expose the data to geometry nodes. It isn't really an attribute,
because it's read-only and it's derived rather than original data.
No features have relied on the "normal" attribute existing, except
for the corresponding column in the spreadsheet. However, the
column in the spreadsheet is also inconsistent, since it isn't an

On the Windows platform allow Blender windows to be created that are
spread over multiple adjacent monitors.
---
On Windows we are quite feature-complete and stable for the creation and placement of multiple (non-temp) Blender windows. We correctly do so across multiple monitors no matter their arrangement, resolution, and scale.
However, there is another way that Blender could use multiple monitors - suggested by a core dev - which is to size a window so that it comprises multiple monitors. There are some advantages to this way of working because the one window remains constantly active and in focus. It also allows a single region (like a node editor) to be as large as possible.
But this way of working is not currently possible. That is because during window creation we constrain them to fit within the confines of the nearest single monitor. This has mostly been done for simplicity and safety. We don't want to restore a saved window to a position where it cannot be seen or used.
This patch addresses that. It allows windows to span multiple monitors, and does so safely by constraining the four corners of the window to be within the working area of any active monitor. This means it allows the creation of single windows as shown below in blue (left two), but does not allow the one in orange (right):

Instead of retrieving which attributes to transfer from the geometry set
which exists at a different abstraction level, get them from accessors
directly with a newer utility function. This removes boilerplate code
and makes the logic clearer for a future even more generic attribute
propagation API.
The evaluated positions cache can live longer than a specific
`CurvesGeometry`, but for only-poly curves, it pointed to the positions,
which are freed when the curves are. Instead, use the same pattern
as the evaluated offsets and don't store the positions span, just return
it when retrieving evaluated positions.
There are known bugs in HIP compiler that are causing random build failures
when making changes to the Cycles kernel. This is preventing developers from
efficiently making improvements to Cycles.
For now Cycles AMD GPU rendering is disabled in Blender 3.6 until a good
solution is found, so that ongoing work like Principled v2 is not blocked.
We hope this can be resolved later on in the 3.6 release cycle.
Ref #104786
This reverts 1116d821dc and part of 5bac672e1a.
The solution was made specifically for the 3.5 release, to avoid
breaking other cases. The previous commit addressed the problem properly
by letting the general menu code align labels where needed.
Usually in Blender, we try to align the labels of items within a menu,
if necessary by adding a blank icon for padding. This wasn't done for
menus generated from enum properties (RNA or custom property enums). Now
we do it whenever there is at least one item with an icon.
Since the menu doesn't automatically align the labels like other menus
and pulldowns in Blender, I manually made them align using the blank
icon. However the menu button would also include this blank icon now.
This is a specific fix for the 3.5 release. In the main branch I will
replace it with proper support for automatically aligning labels in such
menus.
* BLENDER_VERSION_CYCLE set to beta
* Update pipeline_config.yaml to point to 3.5 branches and svn tags
* Update and uncomment BLENDER_VERSION in download.cmake
Usually when a menu item displays an icon, we indent all other items
with an empty icon so items align nicely. Now with more built-in asset
libraries (the new "Essentials" library), this inconsistency becomes
more apparent.
Also add a separator line between the "All" asset library and the
others, makes the menu look more organized.
The Preferences for asset libraries are becoming more than a simple name
+ path. E.g. there is now an Import Method options, and we previously
also considered a Relative Paths option (which we may still want to
add). The previous UI, while consistent with the Auto Run Python Scripts
UI isn't well suited for less than trivial cases. Using UI lists makes
the UI more scalable and follows usual list UI patterns more. There is
also more space for the path button now.
Part of #104686.
The default import method for an asset library can now be determined in
the Preferences. The Asset Browser has a new "Follow Preferences" option
for the importing. The essentials asset library still only uses "Append
(Reuse Data)".
This is part of #104686, which aims at improving the import method
selection, especially for the introduction of the new essentials library
(which doesn't support certain import methods). Further changes are
coming to improve the UI, see #104686.

The quick fur operator now uses the new hair system. It adds a new
curves object for every selected mesh, and adds geometry nodes
modifiers from the essentials assets that generate curves. A few
settings are exposed in the redo panel, including an option for whether
to apply the modifier to generate the initial curves so that there is
original editable data.
The point of the operator is to give people a sense of how to use the
node groups and to give a very fast way to build a basic setup for
further tweaking.

We (Dalai, Hans, Falk, Simon and me) decided that the curves edit mode
is useful enough to justify moving it out of experimental now. So far it
supports the following features:
* Various selection tools. The selections are synced with sculpt mode.
* Transform tools.
* Delete curves/points.
More functionality of the old curve edit mode will be ported over in
future releases.
This implements the delete operator in curves edit mode. The behavior
is similar to the delete operator in the edit mode of legacy curves,
i.e. it's actually dissolving and doesn't split curves. This is also
the behavior that we generally want for the hair use case.
The operator is added to the `Curves` menu and can be accessed via
the keyboard using `X` or `Del`.

This adds a new `Curve Falloff` popover to the comb brush tool settings.
The curve control allows changing the brush weight along the curve to

This functionality could potentially be added to some other brushes,
but the comb brush is the most important one, so that is added first.
I did add the buttons add the buttons to choose a curve map preset.
However, I did not add the preset dropdown, because that just adds

This patch adds a simple operator to set values of the active
attribute for the selected element. The aim is to give simple control
over attribute values in edit mode rather than to provide the fastest
workflow for most cases. Eventually this operator might be less
important compared to more advanced attribute editing tools, but for
now, exposing a little bit of functionality is low hanging fruit and
will help to see the possibilities.
The implementation mostly consists of boilerplate to register the
necessary property types for the operator and draw their UI.
Beyond that, we just loop over selected elements and set a value.

Certain material node graphs can be very expensive to run. This feature aims to produce secondary GPUPass shaders within a GPUMaterial which provide optimal runtime performance. Such optimizations include baking constant data into the shader source directly, allowing the compiler to propogate constants and perform aggressive optimization upfront.
As optimizations can result in reduction of shader editor and animation interactivity, optimized pass generation and compilation is deferred until all outstanding compilations have completed. Optimization is also delayed util a material has remained unmodified for a set period of time, to reduce excessive compilation. The original variant of the material shader is kept to maintain interactivity.
Also adding a new concept to gpu::Shader allowing assignment of a parent shader from which a shader can pull PSO descriptors and any required metadata for asynchronous shader cache warming. This enables fully asynchronous shader optimization, without runtime hitching, while also reducing runtime hitching for standard materials, by using PSO descriptors from default materials, ahead of rendering.
Further shader graph optimizations are likely also possible with this architecture. Certain scenes, such as Wanderer benefit significantly. Viewport performance for this scene is 2-3x faster on Apple-silicon based GPUs.

face was not properly validated.

This better aligns with OSX/Linux warnings.

This renames `data` and `color` to `selection`. This is better because
it's actually what the corresponding buffers contain. Using this
more correct name makes sharing vertex buffers between different
gpu batches for different shaders easier.
The "current file" mode is only useful when creating new assets.
However, the far more common use case and the one that should require
fewer steps is to use existing assets.
There is a risk that this causes freezing if the file browser preview
caching does not work properly. So we'll have to keep an eye on the bug
tracker to see if this is an issue in practice.

Sculpt: Added vector displacement for the sculpting draw brush (area plane mapping only for now)
Vector displacement maps (VDM) provide a way to create complex displacements that can have overhangs in one brush dab.
This is unlike standard displacement with height maps that only displace in the normal direction.
Forms like ears, curled horns, etc can be created in one click if VMDs are used.
There is a checkbox on the draw brush in the texture settings "Vector Displacement" that enables/disables this feature.
Technical description: The RGB channels of a texture in a brush stroke are read and interpreted as individual vectors, that are used to offset vertices.
As of now, this is only working for the draw brush using the area plane mapping. Symmetry and radial symmetry are working.
A few things to consider when making VD-Maps:
* UVs need to stay intact for the bake mesh (e.g. voxel remeshing can't be used to create VD Meshes)
* When exporting a VD Map it should be in the file format OpenEXR (for positive and negative floating point values).
* Export resolution can be 512x512 or lower (EXR files can get very large, but VDM brushes don't need a high resolution)
And when using them:
* Inside Blender clamping needs to be unchecked on the texture
* The brush falloff should be set to constant (or nearly constant)

The Volume property of the Maintain Volume constraint was marked as a

The volume can actually be understood as a factor of the initial
volume, so it should be dimensionless.
Additionally, the volume had a range of 0.001 to 100.0. This is wide
enough in most cases, but sometimes you may need to go orders of
magnitude higher or lower to consider vast or thin objects, and there

A properly authored USD file will have the extent attribute authored on all prims conforming to UsdGeomBoundable.
This cached extent information is useful because it allows the 3D range of prims to be quickly understood without reading potentially large arrays of data. Note that because the shape of prims may change over time, extent attributes are always evaluated for a given timecode.
This patch introduces support for authoring extents on meshes and volumes during export to USD.
Because extents are common to multiple kinds of geometries, the main support for authoring extents has been placed in USDAbstractWriter, whose new author_extent method can operate on any prim conforming to pxr::UsdGeomBoundable. The USD library already provides us the code necessary to compute the bounds for a given prim, in pxr::UsdGeomBBoxCache::ComputeLocalBound.
Note that not all prims that are imageable are boundable, such as transforms and cameras.
For more details on extents, see https://graphics.pixar.com/usd/release/api/class_usd_geom_boundable.html#details.
Note that when new types of geometries are introduced, such as curves in https://developer.blender.org/D16545, we will need to update the USD writer for that geometry such that it calls this->author_extent.
Update on Feb 2: This patch has been updated to include a unit test to ensure authored extents are valid. This test requires new test assets that will need to be submitted via svn. The test assets are attached in the d16837_usd_test_assets.zip file. To use, unzip and merge the contents of this zip into the lib/tests/usd folder.
This unit test also addresses #104269 by validating compliance of exported USD via UsdUtils.ComplianceChecker.

- Rename roughness variables for more clarity - before, the SVM/OSL code would
set s and v to the linear roughness values, and the setup function would over-
write them with the distribution parameters. This actually caused a bug in the
albedo code, since it intended to use the linear roughness value, but ended up
getting the remapped value.
- Deduplicate the evaluation and sample functions. Most of their code is the
same, only the middle part is different.
- Changed albedo computation to return the sum of the intensities of the four
BSDF lobes. Previously, the code applied the inverse of the color->sigma
mapping from the paper - this returns the color specified in the node, but
for very dark hair (e.g. when using the Melanin controls) the result is
extremely low (e.g. 0.000001) despite the hair still reflecting a significant
amount of light (since the R lobe is independent of sigma). This causes issues
with the light component passes, so this change fixes#104586.
- There's quite a few computations at the start of the evaluation function that
are needed for sampling, evaluation and albedo computation, but only depend on
the view direction. Therefore, just precompute them - we still have space in
PrincipledHairExtra after all.
- Fix a tiny bug - the direction sampling code did not account for the R lobe

The existing logic to copy `BMesh` custom data layers to `Mesh`
attribute arrays was quite complicated, and incorrect in some cases
when the source and destinations didn't have the same layers.
The functions leave a lot to be desired in general, since they have
a lot of redundant complexity that ends up doing the same thing for
every element.
The problem in #104154 was that the "rest_position" attribute overwrote
the mesh positions since it has the same type and the positions weren't
copied. This same problem has shown up in boolean attribute conversion
in the past. Other changes fixed some specific cases but I think a
larger change is the only proper solution.
This patch adds preprocessing before looping over all elements to
find the basic information for copying the relevant layers, taking
layer names into account. The preprocessing makes the hot loops
simpler.

The scaling of area light / spot light blend was wrong because it is
calculated for pivot at the edges. The new implementation in theory
works for all `abs(pivot) <= 0.5f`, although we only have -0.5, 0, and
0.5.
- Axis constraint for box cage was only applied when there is translate
flag, now the same logic is applied regardless of the translate flag,
this means when dragging the edge, the scaling in the other axis stays
the same; when dragging the corners, it applies free-form scaling.
- Due to the existence of margin, `data->orig_mouse` does not lie
exactly on the boundary. Using that value to compute the scaling causes
the error to accumulate over distance. The new implementation uses the
original dimension of the object instead, and only uses
`data->orig_mouse` to determine the side of the original cursor relative
to the pivot.
- For circular gizmo with unsigned scaling, the gizmo only follow the
cursor exactly when the cursor stays in the original quadrant, otherwise
it's hard to handle the logic when we should clamp the scaling.

Currently the passepartout color is hardcoded to black. While a
sensible default for cinema, it may make less sense for other media,
whether video, print, web, etc. It greatly affects viewing conditions
of the image and should be user selectable, much like painting
programs allow.

Don't create caps when using cyclic profile splines with two or fewer
points.
This case wasn't handled, yet, leading to invalid meshes or crashes.

Vulkan has a pluggable memory allocation feature, which allows internal
driver allocations to be done by the client application provided
allocator. Vulkan uses this for more client application allocations
done inside the driver, but can also do it for more internal oriented
allocations.
VK_ALLOCATION_CALLBACKS initializes allocation callbacks for host allocations.
The macro creates a local static variable with the name vk_allocation_callbacks
that can be passed to vulkan API functions that expect
const VkAllocationCallbacks *pAllocator.
When WITH_VULKAN_GUARDEDALLOC=Off the memory allocation implemented
in the vulkan device driver is used for both internal and application
oriented memory operations.
For now this would help during the development of Vulkan backend to
detect hidden memory leaks that are hidden inside the driver part
of the stack. In a later stage we need to measure the overhead and
if this should become the default behavior.

The GPU module has 2 different styles when reading back data from
GPU buffers. The SSBOs used a memcpy to copy the data to a
pre-allocated buffer. IndexBuf/VertBuf gave back a driver/platform
controlled pointer to the memory.
Readback is done for test cases returning mapped pointers is not safe.
For this reason we settled on using the same approach as the SSBO.
Copy the data to a caller pre-allocated buffer.
Reason why this API is currently changed is that the Vulkan API is more
strict on mapping/unmapping buffers that can lead to potential issues
down the road.

Keep using the 3 evaluations dF_branch method for the Displacement output.
The optimized 2 evaluations method used by node_bump is now on its own macro (dF_branch_incomplete).
displacement_bump modifies the normal that nodetree_exec uses, so even with a refactor it wouldn’t be possible to re-use the computation anyway.
Using larger integer types allows for more efficient code, because we
can use the hardware better. Instead of working on individual bytes,
the code can now work on 8 bytes at a time. We don't really benefit
from this immediately but I'm planning to implement some more optimized
bit vector operations for #104629.

Add a test to address the issue raised in #103913, where zero area
triangles could be created from polygons that have co-linear edges
but were not degenerate.
Since USD is no longer statically linked these linker tricks
are no longer needed.

Pull Request #104627
When building a node group that's meant to be used directly in the
node editor as well as in the modifier, it's useful to be able to have
some inputs that are only meant for the node editor, like inputs that
only make sense when combined with other nodes.
In the future we might have the ability to only display certain assets
in the modifier and the node editor, but until then this simple solution
allows a bit more customization.

During hair grooming in curves sculpt mode, it is very useful when hair strands
are prevented from intersecting with the surface mesh. Unfortunately, it also
decreases performance significantly so we don't want it to be turned on all the time.
The surface collision is used by the Comb, Pinch and Puff brushes currently.
It can be turned on or off on a per-geometry basis.
The intersection prevention quality of this patch is not perfect yet. This can
be improved over time using a better solver. Overall, perfect collision detection
at the cost of bad performance is not necessary for interactive sculpting,
because the user can fix small mistakes very quickly. Nevertheless, the quality
can probably still be improved significantly without too big slow-downs depending
on the use case. This can be done separately from this patch.
Pull Request #104469
Previously, the node used the "true" normal of every looptri. Now it uses the
"loop normals" which includes e.g. smooth faces and custom normals. The true
normal can still be used on the points by capturing it before the Distribute node.
We do intend to expose the smooth normals separately in geometry nodes as well,
but this is an important first step.
It's also necessary to generate child hair between guide hair strands that don't
have visible artifacts at face boundaries.
For perfect backward compatibility, the node still has a "Legacy Normal" option
in the side bar. Creating the exact same behavior with existing nodes isn't
really possible unfortunately because of the specifics of how the Distribute
node used to compute the normals using looptris.
Pull Request #104414
Like in the 3D viewport, UV Face Selection was previously based on
distance to the face center.
Instead, measure distance to nearest edge instead, which is more
consistent with a 2D viewport.
