Cloud geometry

How to make geometry?

this series does just look fantastic

awesome.
Very impressive karba.
Do you plan to integrate a cloud option in the UI?

Very nice, but... High poly clouds means that I will not be able to add clouds to an existing heavy scene close to the VRAM limit. I would have expected a more procedural solution based on 3D textures, usable with low poly clouds.

It may just be effective to model a few cloud variations and distribute them with the scattering node. You could also have them intersecting to create more random shapes.

Will an alternative to 3d textures be implemented again Karba? Making skies procedurally seems a bit more effective

I said several times in the past that there was a lack of a good Cloud texture like the Cloud texture in Blender. The closet procedural texture available in Octane is Turbulence, but it always show some sharp edges and is not realistic at all when you want to create clouds, or even simple Bump on some materials. I tried to use it on the body of some vehicles, and it was not convincing at all.

Some other approach. I didn't use daylight system. Sky color appears because of blue scattering color.

I think the main problem is the sharpness in the clouds. Usually the clouds are more smooth in their contours.
