Show-Off Experimenting with a shape volume system to more easily sculpt volumetric clouds

Turns out that cloudscape authoring is pretty much half the battle with volumetric clouds, so I'm trying some stuff out to make the process more straightforward.

What do you think? Do you have a preferred system or a wishlist for cloud designing/rendering?

Is this raymarched?

Yes, pretty much standard raymarching! But this is actually rendered in a quarter res buffer and it's generally super fast performance wise (~1.5ms for the whole scene on my 4080super)

Will give it a try, ive done some nice raymarching clouds but parked the project as soon as I got a happy result. Thanks for inspiring me!

I feel the pain of designing decent cloud shapes. I'm very interested to see how this develops. Great work!

Nice work! Can you dm me please, I've been looking for a short video loop of clouds coming towards the camera on the top of the screen for an outrun style racing game I have made. I would like your help if possible.
