I'm just trying to make a simple snow field to fit into a medium sized scene.  I tried adjusting the snow scenes that came with Carrara but they're way too big and complex.  I also tried a simple plane with some displacements but weird things started happening to other objects in the scene (I have no idea why.)

It's just suppossed to be a billowy type of snow that a sled would be sliding through.  Any and all suggestions would be greatly appreciated.
