I'm having trouble trying to accurately render Opaque Channel Glass. Attached are real world examples as well as two project examples.
I've tried Glass, Glazing, and Generic materials. I've even tried modeling the channel glass 1:1. I can't seem to accurately replicate the light dispersion.
In the project example 1, I used a "frosted glass" approach. It's fairly close, except that the objects close the the glass are too visible. The structural framing should be as blurred as the person in the shot.
In the project example 2, I have the channels fully modeled, as well as the fiberglass thread insulation inside. Objects do not show through at all, and the sunlight passes right through (you can see the sun rays).
Has anyone had any success creating a material and/or modeling in a way that accurately represents the real world examples linked?
