…since Wavefront Object format only has a material file ( .mtl ) where it refers to the textures… you might have to export to the folder where you textures are and for transfering have to pack all this in to one archive file…
…also since FBX is proprietary… it doesn’t support everuthing… see also docs.blender manual addons import_export scene_fbx…
I export from Blender, import to Character Creator 4. Geometry looks (mostly) great, but some texture issues are there (some missing, some alphas not working), and objects distributed with geometry nodes don’t show up at all.
Same issues importing to Rhino.
What’s the best way to convert a working Blender model to be “fully compatible” with other apps?
