I made it rain

Today I made rain, it was alot of fun and its not completely done but I am happy with what I have so far. I also made a new ground texture I am still up on how the ground was going to look, grassy or barren. I am leaning toward making it filled with grass and have a small amount of dirt on the side of the stream and a little on the path.

I was looking at my material and thought I would show you my cliff rock master material. I am using an instance material so I can have multiple rocks as for now I have only 2 but am hoping to use 4 or 5.
