hello... I'm new to houdnin from maya and I have a project where we have to disintegrate a person and. I want to have an effect similar to one i've seen in the new x-men trailers... here is the link youtube.com/watch?v=PfBVIHgQbYk . at around 51 seconds you can see the objects disintegrating into somewhat sand like but also still retaining there original color. I know the basics of houdini but I'm not sure how to approach this effect if anyone would be so kind as to help me get started that would be great.
