This Dual Shader gives you the ability to create a snow, grass or any kind of top covering material without having to think of the objects orientation. For instance, create a rock with freshly fallen snow on top and simply rotate the rock any way you like and the snow stays on top.
This Shader lets you implement 2 Diffuse Maps and 4 Normal Maps. You can adjust the Specular and Emission properties of both Diffuse Maps and change the color of the Diffuse, Specular and Emission.
Create realistic Falloff effects to make the snow or grass or anything show, or not, in the crevices of the rock or the bark or any other texture you choose.
