I have been using Blender and the glTF file format for my models. One of the problems I have encountered however is that many of my models use common PBR materials and It is meaningless to reinclude them in every model file. To fix this problem, I have been creating the materials in Godot and manually assigning them to the appropriate parts of the mesh. But this method takes too much time. Is there a way to set the models so that when they are imported to Godot they are automatically assigned through the material ID?
