I've been looking on the forum and searching, and this seems to be a problem that keeps on happening. Well, I can't seem to figure out why my editor refuses to save the materials I add or change. For instance, I create a "CliffRocks" to paint the map. Works like a charm. But when I close and re-open the game, wherever I used the "CliffRocks" material/texture it will have that orange texture "No Material". I've tried with the F11 classic editor and F10. I'm at a loss what to do here. I keep seeing a materials.cs file being mentioned in some solutions, but I assume that has changed to .json format, since I can't find any *.cs file out there. I've also made sure the name of the files, folders and inside each *.json have been changed. Thanks in advance for any help on this. I just started making a map in BeamNG and I'm not going to lie, I'm taking a beating!
