I was about to ask for some parameter to adjust clouds contrast, but i see something similar has been already asked, so +1 from me.

If this is regarding how clouds get big bad hotspots, I also want to add my +1 for contrast control.
This is only for cumulus clouds, not cirrus, at least in my case.

Enjoying experimentation. Used the new sky features on a Calvert Daylight studio model. Some more variety with Cirrus clouds would be good, moving it independently from the main clouds would be good as I see from comments its more difficult to randomise.

100% coverage. Phase across Variety.

Contrails distortion looks weird. Could it be somehow improved to better resemble the actual thing?

Also feature request - i would love to have an option for partial cloud coverage. No need for something fancy like painting maps for explicit control, a simple spinner "horizon bias" would be already great - quite often IRL you can see beautiful clouds over horizon, while sky overhead is completely clear, it would be nice to be able to replicate this in Corona.

I forgot to thank the team for the seed parameter, it's so much easier to quickly evaluate different clouds positions now, so thank you very much! :]

Clouds look great, can't wait to try this out!

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 :)

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".

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?
