Make a tree in bryce 5. Make the leaves "bamboo" shape. Make number of leaves 8, and size of leaves 1 or 2. Make the trunk material completely invisible (in the material lab, make transparency 100% and turn on blend transparency.) Then make the leaf material green. Now, duplicate the tree a few times, spread them out into a big clump, and place them all just so they poke out of the ground. Tada!
