If you are getting this error in Maya:
Cannot find procedure "Unfold3D"there are few possible solutions:
- Make sure Unfold3D plugin is loaded.
- If plugin is loaded, edit file
bt_autoUnwrapUVTool.mel
in maya's script directory and make sure that all references to Unfold3D are replaced"Unfold3D -u" to "u3dUnfold" "Unfold3D -o" to "u3dOptimize"
After edit, to avoid restarting Maya, load script with commandsource "bt_autoUnwrapUVTool.mel"
