In this tutorial I demonstrate techniques for simulating snow covered trees, how to use sun rays, how to add stars in a night sky, how to add tracks in the snow and simulate snow collecting at the base of particle trees.
***Errata*** - At about 23' I connect a Yellow Texture node output to a Green Mix node input. I should have put a Diffuse Shader node between them (it has a yellow input and green output node).
