So, I downloaded these nice conforming sunglasses for V4 from the free stuff and was using them for a render last night. The textures that come with them are ultra simple and I want a better effect on them. I remember a discussion on glass where BB showed some he'd created that looked like the type of mirrored colored glass on some tall high rise building, but I don't think he published those shaders. But the test renders he did look similar to what I had in mind for the sunglasses. He's very busy right now with the Lux exporter project, so I thought to ask if anyone had any ideas. Also, how do you make the material darker at the top and shade to lighter at the bottom?
