Vellum snow


Recommended Posts

Looking sweet!, would you please share a breakdown of the process a bit more?
I am working on a similar scene, and I'm struggling to get the proper shader effect for the snow and I want to render with Karma XPU and CPU

Your snow and specular is looking great.

I'll greatly appreciate it.

For volume I used simple karma pyroshader and render this pass in karma xpu.

For reflections, i cant found solution for XPU yet so I use karma CPU with combination of two pbrreflect one for overal reflection and one for specle. Also I convert volume to mesh for it. For specle I use voronoi noise and samplesphere to randomize normal direction

Well, play with friction, attraction weight and point mass until you find nice look. And I think point mass play main role in all of this )

Thanks, Yeah I have masks for attraction weight and using shape match on top of that. Haven't played around with mass too much so will give that a go.

Any chance you could put that scene on gumroad? Could grab it then for some $.

Thank you

Well, I'm thinking about put it to gumroad.

But with recent release of the MPM solver I think it will be better for snow sims. I didnt check it just saw presentation videos )

There's pros and cons as for everything, so I think Vellum approach is gonna be around for a while. Haven't tried MPM myself yet though. Let me know when that script drops on gumroad. I'll check it out then.

Cheers
