Why does my Ambient Occlusion bake and Exported UV Layout have color from my materials? I have created an object and I have assigned a bunch of materials, each with different diffuse colors (for use in dDo) to different parts of the model. What I can't figure out is why when I bake my Ambient Occlusion map I am getting color information in my AO Map. Clear is the only item that I have checked in the Bake Settings. I am also getting the same behavior when I export my UV layout. I don't think I have ever seen this before and I am totally stumped. I don't have any vertex colors on the model. I have no textures in the scene either as I removed them by holding down Shift and unlinking the datablock for my texture bakes. I have cleared all those out and restarted Blender. All I have is my model and a whole bunch of materials with different diffuse colors, that I have assigned to different parts of the mesh. What would be causing such a thing to happen?
In BI the diffuse color is used to color AO output.

One way to avoid this is to enable Normalized in the bake settings:
