I have got these two issues that I cant seem to solve or find answers. First of all my Glass material seems awful, I seems as if its black espetially when its infront two or more objects with the same material. I have tried playing with the refraction values and opacity vlues however never got a result that feel similar to glass. The other issue I have is that once I add and exponential height fog for a long shot the glass material dosent seems to have its sort priority correct and it looks as if its dead black pixels ( like the fog cant be infront of it). Thank you hopefully its not a bug and its an easy fix.
