Export Alias
The shape in Blender is slightly different than the shape of the SubD in Alias.
There is no support for partial/soft edge creases and vertex creases in Alias. Blender mesh with subdivision modifier and partial creases for edges and vertices, will not transfer correctly to Alias. This is a limitation.
No file!
The addon depends on Alias API, which cannot be re-distributed. Autodesk Alias 2023.1 or later should be installed for the addon to function.
