Hey guys!

I was watching “Frozen”, and there are lots of snow dynamics scenes where horses run on snow and the entire volume of the snow changes in response to their legs movement. You can also see trails, lumps of snow accumulating, etc. I am thinking: how did they simulate these snow effects? In Houdini, I have not tested “Grain” solvers/tool-shelf, but I think this would be the closest way to do snow effects like the one I've mentioned?

Thanks

I think so. See this comment and its accompanying video https://vimeo.com/192893553#comment_15193560 [vimeo.com] … The keyword is “MPM” because the Material Point Method is what Disney used on Frozen.

Hey Ivan, I ran the same scene PBD, and a lot of tweaking of the attractweight attribute to create the chunks, it's much faster and has a different look, much easier to control: vimeo.com/193663289

Thanks Edward … I've heard once: math gives you wings
