The cudaSupport Flag: Moved some non-Blender-specific information to the CUDA page, and added a link to that section. Clarified build information.

=== Installing With Additional Python Packages ===
To install additional Python modules into Blender, use the <code>withPackages</code> attribute.
Example using a normal Blender package:
<syntaxhighlight lang="nix">
environment.systemPackages = with pkgs; [
  (blender.withPackages(ps: [ ps.pyserial ps.fs ])
];
</syntaxhighlight>
Examples using abnormal Blender Packages:
<syntaxhighlight lang="nix">
let
  blender-cuda = blender.override {config.cudaSupport=true;};
in {
  environment.systemPackages = with pkgs; [
    (blender-cuda.withPackages(ps: [ ps.yq ])
#  (pkgsRocm.blender.withPackages(ps: [ ps.pyserial ps.fs ])
  ];
}
</syntaxhighlight>
In these functions, <code>ps</code> is an alias for <code>python313Packages</code>.
Installing with additional packages will result in a binary named <code>blender-wrapped</code> as it adds the python modules by wrapping Blender in a custom Python environment. When using a binary or unofficial Blender nix package, support for this feature will vary depending on if and how the packager implemented it.
A workaround if using a package that doesn't support <code>withPackages</code> is to install the python packages globally.
<syntaxhighlight lang="nix">
environment.systemPackages = with pkgs; [
  python313Packages.yq
  python313Packages.pyserial
];
</syntaxhighlight>
Or if it fits your use case better, you can install them in a nix-shell and run Blender from within that shell.
{{file|shell.nix|nix|
<nowiki>
let
  nixpkgs = fetchTarball "https://github.com/NixOS/nixpkgs/tarball/nixos-25.11";
  pkgs = import nixpkgs { config = {}; overlays = []; };
in
pkgs.mkShellNoCC {
  packages = with pkgs; [
    python313Packages.yq
    python313Packages.fs
#    Optionally you can declare the Blender package you want to use in the shell, so you can run the shell in --pure.
#    Can be useful if you're trying to make a reproducible development shell or similar.
    pkgsRocm.blender
  ];
}
</nowiki>
}}
