D1243 is committed, you should update this patch.
As you mentioned get/setUV() will using the wrong UV map if a material using multiple textures and one of the textures are disabled. But this bug was also before. If you want to fix that you should do this in a separate patch.
Oh,I want to export a FBX file without .fbm folder.I think in the export setting i can do this,just like i export without media file and .fbm.But i try all setting and i can't do this.
I edit the "export_fbx_bin.py"
Thanks for the quick review, I've inlined my responses.
I do not see any bug here? this is just part of FBX files (I assume…). Not a Blender bug anyway.
Thanks, I see
