how to create erosion with particle … before I created sand in Maya but it's not real. How to make Sand with erosion object ?
I tried cookie but it's not good. someone says cookies work when the segment s are very high .. but problem is I've shader on the object.
So I thinks this method isn't good enough………….
Does anyone know workflow about sandman? :cry:

You could use a SOP Solver to define an animated group of particles.
