I use to use anim8or to create objects for NL. It's been a while, but I tried using cinema4D to create them and the textures dont even show. One time I even tried putting objects witn no textures only to have my wooden track's catwalks to have TREES textured on it(weird glitch). Now this time the objects dont even show a solid color on them. And even weirder, I put trees and now my solid colored object is green.
I think maybe I forgot how to texture. What are NL's requirements? Texture size, type, name, etc.?
