Solid polycarbonate

Hi everybody, I've worked a bit on a polycarbonate material.
The "basic" material it's a mix between a dielectric glass with dispersion and a frosted glass, so if you change the balance between the two weights you can have a more blurred or clearer look. Here you have a clear one and a couple of colored experiments.

Due to the fact that colored versions use absorption and falloff, you have to enable volume lighting under settings-->scene-->global settings if you use those. Obviously you can play with falloff and absorption in order to obtain different colors.

Use the materials preferably with unbiased presets, and remember that your model must have thickness.

The model I've used for the test render (is from 3d warehouse) is not very detailed but anyway I think that you can evaluate the material's behaviour decently.
If you add a slight bump and maybe a diffuse map to the material you can simulate a cellular sheet. Perhaps I'll try that later.
Feedback please. :grin:

Notareal and pinoy, you're welcome. :D

As promised here you have a quick test with "fake" cellular sheets with different opacity and colors. The panels are just rectangular surfaces with thickness and only a very simple and light striped bump map on them. The real polycarbonate material can have quite a variety of slightly different looks: from clear and more glass-like to "milky" and more plastic-like and I believe that you can easily tweak the material to suit your need. Obviously the result could be even better if you have time to model the sheets properly. :wink:
