# Maya to Arnold 2027 conda build recipe

This recipe needs the same source archives as the [Maya 2027 recipe](../maya-2027).
See the [README from the maya-2027 package recipe](../maya-2027/README.md) for
instructions on how to acquire or create them, and details about how a conda package
for a Maya plugin can integrate.

## Build Notes
The build script uses patchelf to set relative paths (RPATH) for shared libraries. The paths
(e.g., '$ORIGIN/../../maya2027/lib') are relative to the Maya installation directory structure.
If the Maya installation directory layout is modified, these paths in build.sh may need to be updated to match the new layout.

Symlinks are created to make utilities accessible from the command line.
Additional symlinks may be needed if new utilities are added in future versions.

build.sh calls patchelf unconditionally, but this conda-build recipe only requests maya in requirements/build — unlike the sibling recipe.yaml, which lists both maya and patchelf. If anyone ever builds via conda-build, patchelf would not be in the build environment and the script would fail at the --add-rpath line.

Note also that deadline-cloud.yaml declares only a linux-64 / rattler-build platform, so this meta.yaml is never exercised by submit-package-job. Either add - patchelf here to keep it buildable, or drop the file rather than shipping a recipe that cannot build.

build.sh calls patchelf unconditionally, but this conda-build recipe only lists maya under requirements/build — unlike the sibling recipe.yaml, which lists both maya and patchelf. If anyone builds via conda-build, patchelf will not be in the build environment and the script fails at the first --add-rpath line.

Note also that deadline-cloud.yaml declares only a linux-64 / rattler-build platform, so this meta.yaml is never exercised by submit-package-job. Either add - patchelf here to keep it buildable, or omit the file rather than shipping a recipe that cannot build.

summary: Autodesk Arnold is an advanced cross-platform rendering library, or API, developed by Solid Angle and used by a number of prominent organizations in film, television, and animation, including Sony Pictures Imageworks. It was developed as a photo-realistic, physically-based ray tracing alternative to traditional scanline-based rendering software for CG animation.

The about block describes Maya, not Arnold — it was carried over verbatim from maya-2027/maya-mtoa-2026 rather than adapted for this package. recipe.yaml is the file actually used (deadline-cloud.yaml declares buildTool: rattler-build), so this is the metadata that ends up in the published maya-mtoa package:

  • homepage: https://www.autodesk.com/products/maya/overview → the sibling meta.yaml in this same directory correctly points at the Arnold for Maya user guide.
  • summary: describes Maya ("professional 3D software for creating realistic characters...") instead of Arnold. meta.yaml has the Arnold summary.
  • license: LicenseRef-AutodeskEULA vs. Commercial in meta.yaml — the two recipes for the same package disagree.

Worth syncing about with meta.yaml (or vice versa) so the built package is not advertised as Maya.

summary: Maya is professional 3D software for creating realistic characters and blockbuster-worthy effects.
