Hello LordOfAcid. looks like you have a good start on your desert scene, no need to put it in the "rubbish bin",lol. You didn't state which version of Bryce you had. If you have Bryce5 it is a simple matter to make credible sagebrush by making a tree, down-scaling it, and giving the leaves a pale blue-green color. Dann-O's suggestion to download grass3d is a good one. I made the bleached out grass and vegetation clumps using that excellent free app. I would also check out the links here from the Web Ring as many of them have downloadable plants. planit3d has a lot of free plant models as well. HTH
