I'm getting this error when I try to bake textures on my model. It says "Circular reference in texture stack". I found some info on the net. It says I should disable a texture in the texture stack so Blender won't write the texture on itself. But I don't have any textures in the texture stack. I only have simple materials, no image textures. I'm using Blender Internal, 2.75a. So what should I do to bake the materials into textures? I'm attaching 2 screenshots. The texture is rendered partially, I don't know why. There should be more green and also white (there are two materials on the object, green and white), but it stopped halfway. Also note: I did make an empty image for each UV I unwrapped, before baking.
