I am trying to import a .obj with a .mtl linked to it. When importing it using the 'Import 3D Model' option, everything works perfectly, the material is well kept:
But when I try to import it from a PROTO file, the material is not added, and the model is basically all one color:
Any idea on how to be able to add a .obj and its corresponding .mtl from a PROTO file, so that the texture and faceset coordinates are not described into it (for better readability, as the model is pretty big)?
