With some AMD CPUs (for example 3900X) you can’t use the current Unfold algorithm in Maya.
The error message is: // Error: Unfold3D process error. //
- Open the Maya.env file (inside the Documents/maya/#versionNumber folder).
- Add this environment variable to fix this issue:
MAYA_USE_ALTERNATE_UNFOLD_SHIM = 1Cheers, D
If that is not helping you, there is a different “more or less” solution as well:
