@masonspappy: Thanks very much.
@bobbystahr: With the sunlight coming from the front I could imagine that
the rendering engine has an easier job to figure out the reflection of light on the cloud
than dealing with transparency, translucency and bouncing light. But that is just my poor-mans-math thinking
Ok, instead of working on the edge of the cloud layer in the first cloud I tried something else.
This is a Cloud with a Radius of 7000, a Cloud Depth of 5500, and the Center is at 1850.
The Density Fractal is left at default settings. Edge sharpness 0.5, Cloud Density 0.075,
and Coverage adjust at 0.75. 150 Millions of Voxels, no voxels for shadows.
Ray-marching Quality is set to 1 (I was to impatient to work my way up to a optimized value).
Receive shadows from surfaces = on.
Render GI settings / GI in Clouds: Cloud GI max ray depth at 8, Voxel scattering Quality at 100.
Might both be unnecessary high but I did not want to do more test renders.
Render time about 2h30m with AA at 8.
I like the wispiness and the translucency. tbc...
Cheers, Klaus
