I have wanted, for the longest time, to create a space dogfighting/exploration sim set in a nebula using proper volumetric clouds. This is the closest I've seen to practically generated and authorable tech that could pull it off! Amazing

Thanks Luke! It can probably get much closer to that effect too with some tweaks, there are quite a few sliders 👀

Slightly unrelated but still fun to show; check out dat performance 👀 That's a cloud volume that spans 3000x2000x3000 world units filled with thick fluffy clouds raymarched at minimum 8 units per step and rendered in a quarter res buffer Whole scene averages at 1.5ms (on a 4080 super, but still)

How are you raymarching so performantly?

It helps that it's in quarter res (with depth aware upscaling to take care of edge artifacts). Other than that, I run the whole thing in a compute shader before compositing and I increase the step size in the distance which also seems to help. I think it could be even better with some tricks tbh

Maybe the option to use different types of noises? I have more experience with non-realtime clouds, but you can typically play with different flavors (although I assume mixing noises might get more expensive). Also, using VDBs could be interesting?

Oooh, this, black background, purple blue and pink clouds. Throw in some small light particles, instant nebula. Great work Harry

Thanks Daniel! This could definitely be a nice use case for it 👀

Quick proof of concept for that
