So foam in vray is millions of round sphere meshes? It looks almost like smoke since there are billions of splash particles.
If you look at this video foam and splash do not look like a bunch of little spheres. Are they proceduralyl generated? (basically during rendering vray replaces spheres with a nice fluffy foam texture) https://youtu.be/Oujp1pFa4hE
Not sure if octane can handle millions of physical mesh spheres to create foam like in this video.
By the way does anyone know best foam shader settings to look like in this video? https://youtu.be/J8qJYEXoUaQ
