I have been trying to set up baking for this model I've been working on. The only textures I want to bake are a separate solid black and solid white material that I have assigned to it. Upon unwrapping it, the result is completely transparent. No texture. Not even a solid black texture. Does anyone know what could be the problem? Is there a simple step I could've missed, or maybe something is wrong with my textures? Please give me any information that may pertain to this problem or even to possible mistakes one could encounter when attempting to unwrap a model.
