When exporting to morphine, the face groups cause many problems.
I have no idea whether this is an import or an export problem.
The objects are cut up / the morph targets no longer work …
It might be handy if you could automatically clean up the face groups for export.
There is a tickbox to not export facegroups in the export menu
Only gltf / glb export for Morphinapp possible, and for this there is no checkbox for facegroups.
