CG Shaders – Cubemap Refraction 2

A little update on the last one. This one includes chromatic aberration (rainbow lensing) and all the fancy reflection controls from before. I’m not sure if the contrast adjustments make sense in this case. They work well on opaque reflections, but transparent reflections only really need a brightness boost in my opinion. I’ll leave that up to you though.The biggest change though is that it also has a diffuse term again, so you can add stains and stuff to the glass. The other glass was looking a bit clean for my taste. Overall opacity is still set with a slider though – the diffuse alpha only covers its coverage of the glass. Also, the diffuse is unlit, since lighting it would produce incorrect shadows.So instead I make the specular map do all the work. This may seem odd, but it produces the best look I’ve found so far.
