moure wrote:My two cents on this Normal maps in every renderer ive come across "goes" into the bump slot, so instead of loading an imagemap, noise, or whatever, you load a normal map texture that takes an imagemap ones as input.

jeanphi wrote:Mixing them is an entirely different issue, and defining what it means might be quite difficult, I'm not sure a mix would be appropriate. The only reasonable meaning would be some sort of additive process where you would add the bump on top of the normal map (or inversely), but that would require recomputing local shading surface coordinates to apply the second map.
paco wrote:As for applying them - I would have thought an additive process as jeanphi suggested - ie, first apply the normal map to get the shading geometry, then apply the bump map to that would work?
