Hi, I am creating a waterfall simulation to integrate into a Matt painting, and I cant figure out how to get the spherical particles in the screen shot below, to become more foam like and not so geometric. They are part of the whitewater simulation and i've searched a lot online and asked people and gone through the nodes, but cant figure out how to fix it? Is there maybe a way to create a material for just those particles and change it to a more foam like texture and consistency or smoke, or is there a better way to do it? Really appreciate any help, as quite new to Houdini and working to a fast approaching deadline for uni! :/ Thanks!
