guess I picked the wrong picture for showing the bad glare effect. here is what I mean. about compositing 2 different renderings - both geometries are in front and behind each other at the same time. that makes it tricky to composit in photoshop. so I thought about rendering them out with kind of depth. I tried some blend settings but they give me all the same result. but I guess I have to try it again until it´s working.
