I tried them out and they are more hero bushes and you could pick out their unique traits too easily. But I reworked them to be more generic shrub like, and lowered some other settings so got 3 plus jpeg textures at 17mb which I can share. Jpeg is probably best since textures re basically crap.
Should have smaller leaves but if I go smaller it's patchy and run out of memory for the app, which I believe is 2gb, wasted primarily on GPU preview.
