I’m trying to get a neat light effect (inner light) on a glass object. The attached file contains a test for this. I want the bottom light source to give the glass edges some luminance. Later I want to add some frost effect on the glass and hopefully make it pick up the light as well.
But right now I’m having problem with a light artifact. Some sort of wavy light on the top of the glass. And don’t know why it’s there and how to make it appear more realistic and smooth. Some resolution settings somewhere maybe?
Is there a glass lighting tutorial somewhere that resembles the effect I’m looking for? Or is this just too complex to achieve?
