Our game takes place in a snowy forest, so obviously out trees need to have snow. Additionally we want the trees to be able to swing, so we can't just simply use a static mesh. So we are trying to use SpeedTree, which is great, but it isn't really possible to cover the leaves in snow.
So my question is, can you modify the shader maybe to display different textures (one snowy, the other not) on the different sides of a plane/leaf? Does someone has a solution for this kind of problem?
