Hi everybody! I have this problem. The file is from sketchup, has his own textures from the program. When I build the lights, make a mess with the textures. I try everything, but can’t solve it. When I try with a box, it’s fine. But when I try with a more complex model, happend this problem. I read other posts, but can fix it.
Already solved. Adding unwrap modifier in 3ds Max to the sketchup geometry.
