Attached Link: Shader

I have written a snow shader.

What this does is adds snow to all surfaces facing upwards. There are many possibilities with this, and I need help from the community to develop it further.

This is the basic shader:

I have a much more advanced shader, but this one will be easier for a start, because it is easier to see what is going on. In the more advanced one I have things like trancelucency, refraction, etc, but before we work on that, I have a major problem.

I need a python script that adds this to the existing material, instead of replacing it. At the moment, if you add the shader to the material, it replaces all the other materials. I need a python script that will add this to all the materials in the scene.

So, here is the shader, feel free to mess with it, write python scripts, improve it, etc. If anyone improves it and needs a place to host it, we can do that on Vanishing Point.

Thanks
