I tried using google to find an answer to this question but I kept finding results related to applying normal maps to surfaces. What I want is very different.
I have a very simple model (think cube) which I render as an diffuse image (only use ambient lighting). I want to place this rendered image in a 3d scene (a game) and have light bounce off of it. To have dynamic lighting effects, I need to know the normals of every pixel of the diffuse map.
So my question is, how can I render my model to not show texture or color, but to show its normal "color"? I'm not interested in the normal maps! I want the normal map mapped onto the model. Is there a way to do this in 3ds max?
Cheers,
Rene
