[LVL ED] Outdoor Ideas

[Xanthos]

I very bad when It comes to making maps with a lot of realism.
My indoors are bearable.
But when I make outside maps it looks like a kid with finger paint.

I am not a noob, So I can find most things easily.
I just wanted to know if I can get any suggestions for outdoors.

I mainly want help in these areas.
-Rain
-Thunder
-NON GLITCHY GRASS!
-Mountains
-Lighting.


and I didn't want to make a separate thread but how do I make more than one particle system in a script?
