Vertex Blending and Shaders?

DavidSomin

So the basis is I like snow - a lot. And if I wanna make a snowy village perhaps, would I be able to make my buildings and props not have any textured snow in them, and be able too paint snow onto it through vertex blending?

Would this be available for buildings as well?

You can do that for all static meshes that have a material that is made to support that stuff.

What kind of material are we talking about? Is it easy to make? Because if it is then this would be really helpful.

You can do it with vertex blending and manually paint in the snow where you want, however you can also do it very easy like in that video you posted by using up Vector which does auto blend for you based on Z+ vector. Essentially you get upward mask with Dot Product of (0,0,1) for one input and (0,0,1) that goes through Vector Transform node for other input.

He posted a paper on this too, node setup is a bit different and includes wind direction too, but the idea is same. Pages 32-33.
