Advecting large scale billowy clouds/mist

Recommended Posts


Got a little question regarding the advecten of large scale volumes like clouds. They won't have much of a directional movement but this typical billowing. I build a setup that takes the surface field and places some cross product swirls right under the surface, adjust the noise frequency depending on the depth and also the amp etc... but it's still not convincing me. Do you have an idea how to realize this in an efficient way?

I like the cross product swirl idea a lot. So you created a custom velocity field before the fluidsource?

I recently created an evolving cloud generator based upon offsetting a random fuel pattern. You can find the HIP file here.

Check out Fencer's localized drag as well.
