So I am trying to give the Ambulance Box blue lights, and it is partially working. It is fine when it is off, but when the lights are turned on, missing textures appear on some of them. OFF: ON: Any ideas what is causing this?
send the materials.cs file you have, and a screenshot of your files. It is probably trying to use a texture defined in the materials.cs but that doesn't exists in your folder. Also, open the console and take a screenshot, it should say something about it.
