Note the white line just above the cloud/mist that goes all around the picture. It is an artefact caused by the cloud(cumulus, no weird settings). GISD and GI setting do not effect it and nor do any of the cloud settings as far as I can tell. Has any one seen this before? does anyone know what causes it or a solution for it?
I can imagine it has to do with displacement intersection plus a minimum height. I had that kind of lines several times. Could that be?
Not using displacement intersection but minimum height might with a reflective shader maybe? Ahhhh! possibly the erosion, that's set at about that height, back to play.
Yep! Snow layer minimum height. Cheers Dune.
