There will be a bunch of snow and ice meshes in my next resource pack. Anything very specific you wish for?
I am looking for mesh to create landscape: rocks, rocky cliff, cave entrace, waterfall, trees with snow on branches (standing and lying trres, or tree-trunks, full or cut, with snow on them), any icy ground similar to glacier, stalactites. Vegetation (shrubs, fir tree with snow, or frozen herbs)... animated snowy grass would be excellent, but I am afraid none have been done. Also any item/object having some snow on it (house roof, wooden cart, wooden hut, frozen docks, etc.).
If you have any of them, that would be great!
PS: concerning fir tree, I have a nice model coming from a mod that I forgot. But it is green, not snowy, and the fir trunks is to straight, it looks like a wooden stick. Otherwise, it's a nice fir model that could be rextetured.
