Channel Glass material

[Scott Hand]

Has anyone had any success modeling cast channel glass material?

I am working on a project where the architect wants that Steven Holl aesthetic from a material like these: http://www.bendheimwall.com/ or http://www.tgpamerica.com/gallery/

I briefly tried modeling it "for real" - each piece independently  but it was taking hours just to get through a couple passes. A thick, tiled material could work well if viewed from a distance, but I'm not sure how to deal with the internal lighting and the particularly unique way it scatters and diffuses the light.

It looks like so called sss material (subsurface scattering). Demands lot of calculations in many renderers. Haven't any experience with this in nXt though. Roy may help for sure.
