So i made nissan maxima mod for beamng and the textures worked fine and it was colourable. I then made started making another car, Apollo IE and i only got the glass break textures to work but not the no damage glass texture and it wont change colours. I did have a texture for the glass no damage and the colour texture but it still wouldnt let me change the colour. I used main materials for the maxima so then i used main materials for the Intensa Emozione but it never worked like none of the textures so i used materials.cs instead but that only got the glass dmg texture to work. I really need help.
Sorry, I don't use that, but I suggest studying the Json files in other cars, those files contain the car color information and the different colors you can select for the car in-game. Don't know how to select specific parts to color though, good luck.
