I made a new interior for my XRT and some lights to go with it, tell me what you think

Good work. Some people will like it but it's not for me. Still, good work

You just put a mask over the original lights. It's a good start, put a bit more effort into it and it will look great. Start by making your own light texture, don't use the original. It doesn't have to be complex, any simple design will do. Even a solid color might do. But don't give up.

were do i save interior and lights? (wot folders?)
