Thanks for all the comments guys. I'm quite pleased with the snow on his one. It's actually based one of the first TG2 scenes I made nearly two years ago. It's well worth revisiting old tgd's and updating them with the new features and improvements, not to mention all the techniques and tricks learned along the way.
I'm playing around with the snow method at the moments trying to get more control over placement etc. and will post the tgd when I'm happy with it. No big secret really, just a few layers and careful use of slope and altitude for the shaders. Final normal and terrain normal produced vastly different results in this scene, with terrain normal giving much better large dumps of snow.
I'll be back.
