Lately, I've been trying to fly over the cloudtops on gas giants. I suggest that the shader should lower the maximum bumpiness value of clouds on gas and ice giants to prevent them from becoming too spiky:
The "vortex" noise pattern used on clouds looks OK when bumpiness is reduced, but would it be possible to add a "Jordan hills" texture at a small enough scale that it only becomes visible up close? That might make them look more like clouds.
I think every gas and ice giant should have a cloud layer at 0 height, so that there's something to see if you land on the surface. I've only found one example of a planet like that so far:
EDIT: I've done some experimenting and it looks like SE doesn't currently allow gas giants to have more than one layer of clouds?
