View Full Version : creatng a fuzzy contour - samplerinfo.facingRatio?

05 May 2008, 10:17 PM
I have a character that I'm setting up the textures for and it uses a polygon mesh for hair rather than hair dynamics or fur. What I'd like to do is get it so that on the contour of the hair mesh, it will display little "fuzzies" coming off it depending on the face's normal angle towards the camera.

So far I have the skin sss material reflecting light based on the face's normals to the camera (samplerInfo.facingRatio -> Ramp.vCord -> Skin's reflectivity channel).

I'm wondering how I can use that same idea to make small hair fuzzies so it wraps nicely around the mesh's contour with respect to the camera. I suppose the same idea could be used to simulate the fine hair on someone's arm. This will ultimately be rendering in mental ray.
