Chaos Corona for 3ds Max > [Max] Daily Builds
Clouds playground!
burnin:
Trying to get thin film on clouds, I came up with few feature requests for your consideration:
- rotation & windspeed instead of XY/ XZ offsets (much simpler to control/animate)
- alphas & z-depth (masks, passes) for all Sky elements (for post or as a shader)
- optional extra detail (noise, vorticity, octaves...) (cheap higher fidelity texture results)
and some further quality of life improvements:
iridescent clouds & rainbows (basically colored contrails),
- sun rays,
- night sky...
and more after :)
John.McWaters:
Does anyone have advice on how to create soft, overcast lighting with the cloud parameters? I'd like to recreate the lighting effects from a favorite HDRI of mine (or get close), but I keep getting some pretty strong direct sun shadows.

You control sun shadow sharpness w/ Sun Size parameter. From 0.01 (sharp) to 64 (soft).
With Clouds, control is enabled by turning on "Apply shadows from clouds".
Juraj:
But he probably means automatically, which the current cloud model doesn't do.
So your solution is one version (unless it also dulls the light spread between clouds), second is using single volumetric cloud in front of sun using some nice VDB from internet.
But that would take away the speed and simplicity, and would be worse than HDRi.

Is the 'apply shadows from clouds' checkbox located in the Corona Sky component?
