Abstract glass series.
Posted: Tue Feb 20, 2007 4:24 am
Before the 'bug' found in this thread:- (click me), is fixed I wanted to use it to create some abstract renders.
I've used a simple two layer mxm, with a gradient weightmap for each 'glass' bsdf layer. Layer 1 has ND1.5 and set transmittance colour, layer 2 has ND2.0 and a different transmittance colour.
Mesh object is a 1x1m finely beveled cube, 1cm thick.

2.
3.
4.
5.
6. (The first sheet of glass inside the last.)
More to come as soon as the renders finish.

Well, actually it's not a bug. It's a geometric limitation of smoothing. You should avoid setting smoothing angle more than 30 for 90 degree faces. Besides, smoothing is something like bump in terms of reality. It's not something physical. It's an illusive aid to decrease the requirement of more faces. You know, in real life, no sharp edge turns 90 degrees. There is always a microbevel and again it has infinite recursion. Thus, the above is just a model having improper smoothing angle threshold according to its biased topology.
