Is that even possible? It rendered the hair last as a post process, do I'm not sure it could do what you are asking? Maybe some node does that. Does the hair even actually have a normal? Or is it only the guides that have it?

Hmm. Sas isn't geometry and doesn't exist in the scene, so none of the usual ways of generating a normal map will work.

However, you *might* be able to generate something useful by going back to first principles with normal maps, and setting up a copy of your scene lit with red, green and blue lights along the axes.

That thread explains it partly, but there are probably plenty of other places with more detailed explanations of normal maps, just waiting for you at the other end of a Google search. RGB lights along the axes is how normal maps used to be made back when some clever dick very first thought of them...

It won't work - SasQuatch doesn't have Node Editor..

Incidence node in that thread is using Spot Info > Normal.
