So I've got three Easy cloud systems at various altitudes. The atmosphere is very dense and I've animated the Growth parameter to rapidly shrink the thick, heavy clouds. The sunlight comes streaming through it.
Plenty of GI cached frames which I'm interpolating resulting in a very clean looking 'tgCloudIndirect' pass. However, my 'tgCloudDirect' pass is showing significant flickering in the larger shadow masses of the clouds closest to the sun. Despite having pretty strong quality levels. AA6, Micropoly detail 0.1 (no terrain is visible, so I suppose it can be this low?), Ray marching quality at 0.8, Cloud GI quality at 'Sequence Quality x4', Cloud GI max ray depth 2, Voxel scattering quality 50. Pixel noise, while visible is acceptable and not the issue here. Flickering only really starts once the growth parameter starts decreasing. I'm thinking shadows are the culprit? Any suggestions? Testing disabling 'Use voxels for shadows' now. Fingers crossed.
