This addon is currently beta quality. There may still be major bugs and rough edges, but in general it should *basically* work. Due to limitations in Blender's Python APIs there are also some rough edges that are unforunately impossible to fix at the moment.

This addon requires Blender 4.0 or later.
Compatible with Blender 5.1.
