The back side of the default US-size license plate looks exactly how it should, with a single flat colour and an inverse normal map. Not sure when this was added--perhaps in 0.34 to go with the Nine--but it looks fantastic. However I'm trying to make a new plate size and I have no idea how to replicate this behaviour. I would normally try to use the US plate as a base for the new size but I can't figure out which files are responsible or where they are. The mesh for the US size is nowhere to be found and I've had no luck with main.materials.json. So far I've got my plate in the game and looking good from the front, but I can only make the back of the plate invisible, which is the behaviour of the default EU plate, or a full-colour mirror of the front if I put doubleSided = "1" in the material file, which looks even worse. I also tried copying licenseplate-default.html into my mod but no luck with that. Any insight into how I could do this from scratch, or at least where to find the relevant files/code, would be much appreciated! I've attached my mod in case it helps.
