Dynamic Paint - Snow Test

A simple experiment trying to make realistically gathering snow in Blender.

To do this effect I used an "incremental" Dynamic Paint displace surface with very low negative "displace factor" value. This made snow to slowly increase displace on areas where particles touched the mesh. Then I just added another "white paint" surface on top of it.

Snow surface is a bit too bumpy due to over amplified effect of individual snow flakes. (To not have to render 10 minutes of snowing. :)
