I realize that it's difficult for you to diagnose without seeing something but I thought I'd just do a quick post in case one of you said, "oh yea, just do 'xyz' and they will go away."
I have a scene that is backlight by a rising sun in the scene that's in your face. Imagine watching a sunrise. The sun is already above the horizon. The trees I have in the foreground have terrible fireflies all around the edges of them. I'm using Corona Render, latest daily build. Is this common and are there accepted methods to mitigate this?
