I've been working on my long travel mod that adds a new frame into the game with some extra parts to make it look better and more correct for the theme. However with my other additions so far I've used the materials.cs format but for the frame stuff I'm using the main.materials.json format. I have all files in the correct places and it looks to be correct in the .json file (I have also verified the code) but just appears chrome rather than have the coloring, AO and normals. Any help is appreciated and if needed I can upload files/more screenshots or any other info.
