I was planning on doing something just for my own projects:

1. Get metasequoia lite version. It's free.

2. Use the blob function on the sphere creation.

3. switch to move and scale etc, to smoothly change the look of the emerging fallen snow pile.

4. export to DXF or lwo

5. import to Poser 6.

6. make it into a prop. or, to make things more difficult, put it into setup room and convert to figure with boning etc.

I think that's how I planned on doing my fallen snow prop.
