Is anyone aware if volumetric clouds can be rendered as separate layers? (using Layers, deferred rendering that includes alpha and multiplayer EXR)
For the moment all my tests have rendered pure black images. I am at a loss here, any help would be appreciated.
This is possible and OOB feature for Ultra Dynamic sky (just as an example).
The VoluClouds™ of Unreal are a raymarched material, so it’s a trace through noise-across-3d-space. You can turn this ray on, off, bend it, whatever; it’s done in the material based on what it hits and values derived therein.
But yes, you can do this or whatever you want, you will have to math your way to it though. Likely, in whatever material there is some tracing-length, tracing-start/stop, or ‘altitude’ parameter, start looking in/around there.

Were you ever able to figure this out? I’m wondering if this can be done
