Frosty Ice Shader version 1.0, for Mentalray Maya 2009.
For best results, use a High Dynamic Range image as an environment texture. You can find great HDRI-maps at Paul Debevec's website www.debevec.org
The shader is 100% procedural which means that it uses only 3d-textures and that there is no need to consider UV-mapping.
The shader is mia_material_x, it is backwards compatible with maya 2008 (mental ray 3.6). To open the file in maya 2008 check "Ignore Version" in options when you open the file.
Tweak parameters on the "ice_cloud"-texture for variations in the surface. Lower the transparency (~0.15) to get an even more cold and snowy surface. You can of course also plug the texture into the displacement channel for added mesh detail.
