I have a car scene with some cameras in it. I have written code to render the car image as seen by the camera. What I want to do is get a surface normal map similar to the photos below.

I tried searching for how to get this done, but I couldn't find anything. Any help is appreciated. Thanks!

This is an old tread, but I just stumbled by.. A fast way to do this, is to use the Matcap preview in the 3D view, and select the "normal sphere" in the matcap images/balls. Then simply screengrap!

If this is not good enough, it would be easy to make a material that would do it.
