Renderman Skin Shader

Recommended Posts

I am trying to create a realistic skin shader in renderman in Houdini but my skin keeps rendering with very hard bump. almost looks like stone.

I tried upping the SSS but it doesnt make much difference.

 

Is there a tutorial on how to make a good skin shader in PRman + houdini?

There are these, they should shed some light on the SSS process in PRman.

Should not be problematic to translate what is talked about to Houdini.

One issue I have had with PRman SSS is that the Mean Free Path Distance does not match Maya's, you should be able to tweak this with the "Unit Length" (if I remember correctly it should be 0.001 for Houdini) and adjust it according to what you units your model is in.

Hope that helps.
