The difficult part of translucency is determining where the object is thick vs thin- the shaders just don't have that kind of info available to them. SSS suffers from a similar issue- when a shader is called, it is called for a single point. You have no access to the points around you (to determine if they should be scattering light into your point). I'm playing with stuff to try and address some of these issues, as is Eric- see his message about the edge shaders which could help control translucency- if you have both, combine it with Lit. markd
