This node generates snow buildup on objects by scattering points on up facing polygons of the incoming mesh, copying some spheres onto those points and then voxelizing and smoothing the result.
How far the snow will wrap around the object. 180 means full hemisphere, 0 means only surfaces perfectly facing up.
Number of Snow Points
How many snow drops to generate on the surface
Point Size (Min/Max)
Size range on each snow drop, which turns into a sphere.
Blur the snow volume
Grow or Shrink the snow volume
Blur the final generated snow mesh
Vertex Colors on the output mesh
Reduce to # Polys
Limit the snow mesh to this polycount
Boolean Against Original
Remove faces that are inside the interior mesh by boolean the 2 meshes together
Output the original input mesh merged in as well
