TrueSky Volume quirk

Someone on the TrueVFX Discord showed a weird fringe artifact on their rendering of a CloudScape asset using TrueSky. I recreated the same issue -- look at that ikky border!

I did some further experimentation. One, I think the issue is mostly down to fridge particles being de-noised into meh. Upping the volume resolution using Light Paths - Max Bounces - Max Steps and the Volumes setting make the issue go away.


TrueSky Dusk pre-set - Volume Rendering Defaults

TrueSky Dusk pre-set - Volume Rendering LightPaths/Max Bounces 128 max steps. Volume 60

Same setup with Physical Starlight and Atmosphere
