Only part of a cartoon scene. I just use fur to produce the grass effect, combined with building models in cartoon style. Well, the final result satisfies me.

As for the ground texture I just use the noise, adding 3 noises (black, grey and white) together. Then I adjust the noises' size and color to get the ground's color. And copy the 3 noises as the hill's texture, then adjust noises' size and color to get the hill's darker color. Next make a texture (in black & white) in photoshop, use it to distinguish the area of ground from that of thehill.
