Subject : normal maps and sss Skin shader
Don't know if anyone else has this problem, but normal maps plugged into the bump port of the sss Skin shader does not work.
 
Bumps work just fine, so I'm wondering why not normals?
for now.. I cheated it using a bump map generator node with high factor to drive the normal map, but the result is not as nice as the normal map node...
 
Any workarounds? or a quick way of converting normals to bumpmaps?
