Hi, well, I too did think of that approach with a spiked-terrain, to simulate (plain) grass , but wasnt very satisfied (and had no time, to try it again). Here was my suggestion, which I mailed directly to J_Bondo, last November, when I had no access to the forum). Maybe, someone can make use of my observations with the best scaling. Hubert ***** (qouted) ***** ... noticed your request, yet have no solution to offer, only a small suggestion to provide. So far, I myself also tried to fake grassy plains/hills, yet didnt succeed. At least, I got a crude lookalike; see attached br4-testfile, which makes it easier to follow my explanations: a) creating a terrain, deleting-it-to-new, only creating spikes, cutting off the black as level, using some green texture from mountain-textures. b) duplicating that terrain and rotating it by 180 degrees at the same place. Doesnt look as regular, as spikes of a single terrain. c) changing the colors and tint of terrain2-texture slightly. But it still looks crude and only is a plain. Will nevertheless try some more. I noticed, that a terrain-grid of 256 seems to work best for that grass-effect. Greater than 256 makes it even worse?!! And stretching the size to >81 (default) makes it look like ugly, pointed leaves. Also, if duplicating it, slightly-smoothing, using less-height and placing it on top of the other. Nope, looked more like funny, thin mushrooms, than intended wheat! Me still unsatisfied. Me still no idea, maybe somebody will invent a real 3D-texture like hollow material???
