Thats really good I think. Just a little too extreme. But I can clearly see that with a snow ice effect it would work really well. The crystals idea is good too, would love to see that in TG.
Hannes posted a free plug-in for max, that had some crystals in it. I don't have max or I would be all over it. When I saw that post and link I really thought I would see people use it here. If you can, or anyone can make good crystals in TG I would really enjoy to see the pictures!
