Yeah, it's not the clearest post. This refers to the render option available in carrara to render a normal map.
I set it to use the gbuffers and render to tif.  Because it looks like a rendered picture I was unsure. I could see using it on something kinda flat, like a coin, but in other instances, I don't know. Creating a normal map via rgb channels for a texture map in a 2d program I have done.  This one  being what appears to be a 2d render, particularly on non-plane-like objects I was not sure about. I do understand normal maps, but this particular feature seems unclear. Say, I have a face. I render a normal render to tif w/ the buffers. I don't see how that is going to make a good normal texture map for the face.

No need to think outside the box....
