If you are going to do this make sure you have uv maped everything first then just apply a simple shader to it. That way if you do have spare time all you got to do is apply the texture, and at least you`ll have some color. I always have trouble adding textures after I`ve finished animating but that may be because I model alot of characters so skinning and stuff messes them up, I don`t knowSo i'm probably going to start animating on Monday regardless of the progress with the lighting and texturing, figuring that i can always add them afterwards if necessary but the animation is the main focus of the film.
