Hi all.
I've been maintaining http://skyrim.nexusmods.com/mods/19660 for awhile now and since it's inception people have been requesting two things:

• that I make it so that snow doesn't appear on http://skyrim.nexusmods.com/mods/images/19660-1-1348291698.jpg.
  
• could I add a cold breath effect.

I need some help to nut-out these requests... Unfortunately I think I've reached my maximum understanding of effect shaders - they are pretty confusing to look at.


You can see the set-up for http://trevorbrennan.com/dev/getsnowy-shader.jpg (based off vanilla frost spells & Chesko's Frostfall)


Ideas for #1:
- There is "Affect Skin Only" flag, which isn't exactly what I want but maybe there is a hook there I can use?
- I don't think shaders stack, so maybe I could add an "Affect Skin Only" shader on-top to cancel those areas out? (not likely)

Ideas for #2:
- If anyone understands shaders, is there a way I can make the particle effects come from a coordinate?
- I know WATER's Get Wet effect used a model for the drips, but I'd rather keep this mod as vanilla as I can.


Would love to brainstorm some ideas with the community.
Thanks
