4 variations of terrain conforming snow props for mountains.

Recommended mod - Adaptive Prop Visibility Distance (so props don't disappear when zooming out)

Known issues:
When zooming out terrain is less detailed, this can make the props partially disappear or flicker.
Culling - looking away from a prop can make it disappear.
They're kind of floating, so they don't get swallowed by the terrain too much, so use them for mountains in the distance, not ones you're going to zoom in on.
