Hey! I interested in making a custom engine model for my Cummins mod but I'm not sure how to, I would greatly appreciate maybe just a little guidance I am not so worried about the actual modeling part in Blender, but I am not sure how the "Materials" works and the coding in the engine JBEAM I have an example from the Hopper i6 Engine (so the Flexbodies, Nodes and Beams and Materials), I'm not sure if the "skin.materials" is needed so I included it anyway.
