Low-poly cavity map?

konstruct

Im working on an asset that is fairly high-poly to the point where it doesn't need a normal map. Its all cleanly unwrapped, and now I want to create a cavity map for the texture-



To clarify, I am not talking about an AO (ambien occlusion map) but rather a map that darkens valleys, and lightens peaks. Generally I would generate a cavity map based on the normal map, but since this asset doesn't have a normal map, I don't really have much to work with.


anyone have any ideas?

In max you go Main Menu > Rendering > Render Surface Map.

I think xNormal also will generate cavity maps.

NICE!!! not quite the end result I`m looking for but pretty damn close. udamanVIG

Try the curvature map option in xnormal. Make sure you've set it to three colours. It should spit out a map where red=convex edges and green=concave (I may have got the colours wrong here). You can then copy/paste the colour channels into your texture to use as you like.
