Does anyone know how to make a really nice glass shader in XSI? Since mental ray handles raytracing more than well im sure it's possible to make a really sweome glass...
You could build one manually, using the incidence node.
or
There is a nice glass shader in the Netview. Much easier. Netview>XSILocal>Library>Render>Glass.
There are also some glass shaders here on highend as well as on my site.
