Being inspired by Ravyn's post about bottle transparency, I have been playing with YafaRay glass. In the image below, the bottle in the middle/back is the control subject with only a very very small amount of Distorted Noise Procedural bump added. The left bottle has color added and a larger amount of Distorted Noise Procedural bump. The right bottle is a Blend material made of a Glass material and a Shiny Diffuse material with Musgrave Procedural color and Musgrave Procedural bump.
