- Fixed double import - Improved Cleanup mesh, includes removal of empty shapekeys and unused vertex groups. - Optimise Armature now includes fix broken names function - Optimise Weights now includes a limit for bone weights - Material conversion now handles transparency - automatically rename bones to a standard naming convention such as _Left _Right Still no where near complete, but I getting there.
