Curvature Maps in Max9?
polycounter lvl 18
Just curious if anyone know anything about this, I'm looking to try out curvature maps in my texture work flow and I'm having a bit of trouble finding how to bake them in max.

Mop : what he wants is a shader that samples surface curvature (concavity and convexity) to be able to bake it with specific values.This is only useful if your texturing process relies heavily on that kind of maps, basically you can take one of these and extract concavity, convexity and flatness from them. This is not a cavity or dirt map. I contacted Jogshy a little while ago so that he could include them in Xnormal, but unfortunately this is rather complex to do and the xnormal output is not usable as of now.
edit : try the surfaceshade maxscript from that guy : http://www.gotogrant.com/?page=_scripts

cavity map
gcmp and renderhjs, nope that's not it
uh. . . ya.
Vahl: The link you gave seems to produce a similar effect to what using Crazybump on a baked normalmap does (although I understand it's not the same, since if you use it on a tangent-space normalmap you're only getting the "relative" curvature of the highpoly in relation to the lowpoly), however I guess it's used for the same thing in texturing, eg. as a base for masks for dirt (inside the inward curves), or scratches and wear (on the outward curves)?

Something similar to this is what you get when you generate a displacement map using a subdivided model without any work of sculpt (instead of a flat grey)
