Without removing the `rm … FindEmbree`, compilation fails due to various
macros depending on the version of embree. The nixpkgs history provides
no indication of why this patch is done (it has been present since the
addition of embree as a dep in
6b74f99abd), and the build succeeds
without them, so remove.
Blender addons that have native extensions need to be built against the
same Python that Blender was built with. This makes it easier to write
such addon derivations.
Has been broken likely since edcd3849a6.
First failing Hydra: https://hydra.nixos.org/build/211894618
Notes from attempt to fix:
- The initial breakage may be easy to fix, but the upgrade to 3.4 added
a lot more hurdles
- The patch fails to apply, but is trivially naïvely fixable
- At least some of the existing darwin-specific substituteInPlace no
longer find anything
- When building with naïve fix for patch, fails with:
> Could NOT find USD (missing: USD_LIBRARY USD_INCLUDE_DIR)
for reasons that are not clear to me
The package has been broken for two months and no open issues, so
marking as broken as it’s not going to fix itself and if there is will
to fix it, someone can. For now, leaving the darwin conditionals in
place so not as to make a would-be-fixer’s job harder.
with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
keep a couple of packages "using" openimageio_1 - both are broken
anyway, but as such we have no evidence that they work with 2.x.
all are liable to get removed in the near future anyway.
Enables the WebP image format support in Blender. It has been [supported](https://developer.blender.org/rB4fd0a69d7ba) since Blender 3.2 but was disabled due to libwebp missing from the build inputs.

There are many different versions of the `cudatoolkit` and related
cuda packages, and it can be tricky to ensure they remain compatible.
- `cudaPackages` is now a package set with `cudatoolkit`, `cudnn`, `cutensor`, `nccl`, as well as `cudatoolkit` split into smaller packages ("redist");
- expressions should now use `cudaPackages` as parameter instead of the individual cuda packages;
- `makeScope` is now used, so it is possible to use `.overrideScope'` to set e.g. a different `cudnn` version;
- `release-cuda.nix` is introduced to easily evaluate cuda packages using hydra.
blender 3.1 now requires python 3.10 and zstd to build. also pin
cudatoolkit to 11 and optix to 7.3 as requested by the blender build
instructions for 3.1
