I am very, very new to Blender, so bare with me.
I had a friend make a model for me. He assigned two textures to two objects called "Cube" and "white." Each works properly when the render view is closed, but when I generate a render, no matter what pose, all textures disappear, and the model is solid black without shading. How do I fix this?
