Testing a Snow Macro

Rendered straight from WM. Testing a new snow node. The snow node that’s included with world machine is a bit slow and I can’t grab the deposition of the snow to use as a mask for coloring or whatever.

Basically I take the flow heightfield from an erosion node, expand it, blur it, crank up the contrast, and then a slope selector mask is subtracted from it. Then I use that result as a blend mask between the eroded terrain and a gently blurred version of it. The blurred version is slightly higher then the unblurred. Simply snow. I still need to optimize this one further as I’d like to get rid of the expander.

Did you gain any time while building using this method compared to the snow node?

Hey, may you could post the graph here?

Best regards
