Houdini - Pyro grain advection (scene files)
Just playing around with a computationally cheap setup for doing some underwater type motion. I used grains here but you can use the exact same setup with the bullet solver and packed prim's for real collisions - but here I kinda like the look of the lighter material, almost looks like it's melting into itself a bit, like some softer materials would, under water...
