I'm a little lost on this and I couldn't find an already made thread, can anyone help me? There is this rock texture I want to put as the ceiling on one of my custom maps, and it doesn't work to just type in the name. I've made sure the capitalization is correct and I've also tried it both with and without .jpg on the end if thats the problem. I'm thinking I might have to make an actual .material file because it calls it Ceiling Material instead of Ceiling Texture or whatnot, but I have no idea how to do that if thats the case either. The texture is download, so its not from the original game. It works fine everywhere else though.
Does anyone know what to do?
