This option has been removed in vs2026 and will cause a build error,
disabling this option results in our default /DEBUG being used
which is equivalent to /debug:full which is the suggested
replacement
There is no CMake version yet that support VS2026, support is
currently limited to ninja based builds.
CMake does not know where to look for the MSVC 2026 Runtime
it copies the wrong CRT leading to startup issues, for this reason
WITH_WINDOWS_BUNDLE_CRT has been disabled for VS2026 + CMake < 4.2.0.
Builds done with VS2026 are for this reason *NOT* distributable to
end users at this point in time.
CMake 4.2.0 Is *expected* to have VS 2026 support [1]
But further testing is likely required.
Things of note:
- They stopped using the "preview" channel and have rebranded to
"Insiders" the make.bat options have been updated accordingly to
select the 2026 Insiders build, you need to pass 2026i to make.bat
- All tests seem to pass on my system
- No new warnings, pretty smooth update

Prior to this commit, the Rocky Linux dependency builder environment
setup script would download the latest version of CUDA rather than a
specific version.
This makes it harder to ensure a consistent environment for people
building Blender's libraries, and recently, it has lead to errors
building some of Blender's dependencies due to incompatibilites with
the latest CUDA version and the library versions we build.
E.g. The OSL version we use does not work properly with CUDA 13.

Blender had some support for using MoltenVK. However there are some key
issues why MotlenVK cannot be used. Bugs have been reported up-stream.
As it doesn't work and holds back regular developments it will be removed
from the main branch.
Any efforts on making Vulkan run on Apple (including KosmicKrisp)
is considered a community effort and can be done in a development
branch.

The setting is called `lfs.remote.searchall`, the `remote` part of it being
an exact string, it is not to be expanded with the name of the remote.
Whenever name of the remote is to be used Git documentation uses `<remote>`
syntax.
Tested by triggering the original issue (clone the Github mirror, make update,
wait for a new LFS object appear in the upstream, make update again). Before
this change the LFS object will not be fetched, and based on the Git Curl's
log only the github origin was used to fetch LFS object, none other remotes
were tried.
Also confirmed by checking the Git-LFS code:

This follows the other CMake "modernization" commits, this time for
`bf_intern_openvdb` and the OpenVDB dependency itself.
The difference with this one is that `intern/openvdb` becomes an
"optional" dependency itself. This is because downstream consumers often
want to include this dependency rather than openvdb directly, so this
target must also be optional. Optional, in this case, means the target
always exists but may be entirely empty.
Summary
- If you are using BKE APIs to access openvdb features, then use the
`bf::blenkernel` target
- If you are only using `intern/openvdb` APIs then use the
`bf::intern::optional::openvdb` target (rare)
- For all other cases, use the `bf::dependencies::optional::openvdb`
target (rare)

Add a [Python code generator][1] that takes an OpenAPI definition and
outputs the corresponding data model as [dataclasses][2]
This is intended to be used in the Remote Asset Library project, to
create, download, parse, and validate information of a remote asset
library.
[1]: https://koxudaxi.github.io/datamodel-code-generator/
[2]: https://docs.python.org/3/library/dataclasses.html
## Running the Generator
The generator is a Python script, which creates its own Python
virtualenv, installs the dependencies it needs, and then runs the
generator within that virtualenv.
The script is intended to run via the `generate_datamodels` CMake
target. For example, `ninja generate_datamodels` in the build
directory.
## Details
The virtualenv is created in Blender's build directory, and is not
cleaned up after running. This means that subsequent runs will just
use it directly, instead of reinstalling dependencies on every run.
## Generated Code & Interaction with Build System
It is my intention that the code generation _only_ happens when the
OpenAPI specification changes. This means that the generated code will
be committed to Git like any hand-written code. Building Blender will
therefore _not_ require the code generator to run. Only people working
on the area that uses the generated code will have to deal with this.

Some users still have issues getting LFS files downloaded properly, though the
exact cause is unclear. Normally with a properly installed git lfs, git pull
should already take care of it.
When for whatever reason that is not the case and files have not been fetched
yet, now do lfs pull which is the same as lfs fetch + lfs checkout. Even when
git pull can not run.

Add a simple deprecation message to warn users that macOS pre-compiled
dependencies are no longer provided starting with 5.0, and that they
should either build the libraries themselves or downgrade to 4.5.
This is what the warning looks like in context:
```
$ make update
git lfs install --skip-repo
Git LFS initialized.

The issue was that `git ls-files` will per default escape unicode
characters. This make it so that our python script couldn't find any
files or folder as it expected unescaped characters.
This reverts commit 81e862140f
binary packages turned out to have issues for debug builds on windows
as they link to python_311d.dll and none of the binary packages offfered
on pypi offered a debug build. Building pydantic from source was rejected
due to no rust build infrastructure being in place yet and deemed not
worth the effort for this one library dependency, an alternate solution
was chosen by the assets team that requested this dependency.
This moves the logic to create the parent folder to data_to_c itself
rather than having cmake do it, preventing several thousand cmake instances
to be started.
see pr#141404 for details/benchmarks
Pull Request: https://projects.blender.org/blender/blender/pulls/141404
As requested by @dr.sybren and approved by the admins
Also pydantics deps :
annotated-types 0.7.0
pydantic-core 2.33.2
typing-extensions 4.14.0
typing-inspection 0.4.1
these are installed as binary packages agreed upon with the admins
versions determined by just pip installing it and seeing what it dragged in.
as some of these are binary packages that will differ per platform, there will
be a per platform hash for some packages now unfortunately

When USD sends work to the GPU (dispatch) incorrect datatype conversions
can send incorrect vulkan commands. This happens on AMD GPUs. This PR
will patch USD to limit the max allowed limit. A better solution would
be to only use uint32_t in this function, but there is no `GfVec3u` data
type and I didn't want to do to many changes.
**TODO**
- [x] Validate with @ZedDB that this compiles and solves all the issues
- [x] Add other platform maintainers as reviewers. This is a Windows + Linux issue.
- [ ] Rebuild the USD library including this patch.

On the macOS deps builder, if certain libraries were installed
system-wide using Homebrew, they could be prioritized during the
linking of dependencies over our own versions, causing breakages
when running the built libraries on other systems.
For OpenColorIO, homebrew Imath could be linked if installed.
For TIFF (& libjpeg as a transitive dep), homebrew libdeflate
could be linked if installed.
This commit fixes both of these issues by directly specifying the
library path to prevent the linker from wrongly inferring it to a
system-wide path.
This requires a minimum driver version of 535, however most devices
were already requiring 570 due to the CUDA toolkit version.
The update is required to be able to use an API function for correct
stack size calculation.
Code for older API versions has been removed.

When binary files managed by git-lfs are not hosted by the main source
repo (e.g. when using the github mirror), the fall-back repo set up by
`lfs_fallback_setup` does fetch the files, but the follow-up call to
`git pull` in `work_tree_update` does not check them out.
This commit simply adds an extra `git lfs checkout` command there.
