I'm not sure where this is supposed to go, so if it's in the wrong place i ask a mod to move it.

Anyway, here's my problem.
If you take a look at the screen shot of my desert:
(ignore the bad tent model in the middle, and i have no idea what happened to the top of the picture, doesn't happen ingame)



You can see it's not very interesting.
Does anyone have any tips to make it more realistic, look better, or anything like that.. Maybe a heat haze shader or some plant models? any suggestions to alter the terrain? thanks!
