In the free version of Bryce 7 over at DAZ...seems they're giving it away for a while and the trees in the tree maker editor export really well with either the native procedurals converted to .bmp maps or with your own image maps as .obj. Bryce uses a polygon object shaped like a leaf but you can save the U/V map from in PoseRay and in any image app, fit what ever leaf you desire to that map. PoseRay's cubic U/V mapping helps a lot with the trunks...Takes a bit of tweaking to get the leaves the correct scale in Bryce but I start too big and go down myself....
