So I'm building your typical extreme glassy, displaced dohicky. Was getting your usual black refraction artifacts. Boosted the refraction depth to astronomical values which worked nicely but I was still getting some blackness. After messing around with just about every shader including the architectural shaders and the diffraction shader, I discovered that raising the reflection depth eliminated some of the black artifacts. Can someone please tell me why this is so when my object currently has no reflection whatsoever?
