I got a fairly good desert effect by "carving" a gully out of the infinate plane using a negative terain, then using just a thin layer of haze the same colour as the ground and a good chunk of near cloudless sky. That gave a grood "endless desolate sand" kinda feel. All the terains textured in world space with the same texture (kinda goes without saying eh?). A little ambience on the ground helps the "its too bright" feel of the desert. Didn't manage to get the heat haze though. Check out the image on the link attached. There's another desertish image in my gallery but it cheagts but using twilight and cliffs across the horizon.

what do u mean by "negative terrain"? can u plz explain how to make/use one?

I think a negative terrain is a terrain-mesh with the model set to negative in the object-attributes (the model is neutral/normal at default setting). But when using terrains for boolean actions be sure to set it to 'solid' or 'volume' (or however it's called) in the terrain editor.

can anyone plz be more spesific? sdnoble maybe?

You create 2 terrains (1 to cut out of the other) got to there attributes (click the liitle a) and set 1 to positive and the other that you want to use as the "cutter" as negative then group the 2 togther after postioning. The negative terrain will cut into the positive terrain. Is that any clearer?

yep, much clearer. thank u very much!
