HI.

"Import-Export: Wavefront OBJ format" An error may occur if this blender addon is not valid.

thx for the reply enabling import obj addon solved the issue it might be wise to add error warning message: 'Import-Export: Wavefront OBJ format' addon must be enabled.

This might need some extra care for blender 3.2 too, as there's a new obj importer

[joepal1976]

The fix in https://github.com/makehumancommunity/mpfb2/commit/a9782acc239343747702c1464b372a54681e560a seems to be valid for 3.2.0 too.
