yes I want to do what you did there, a few regular trees then a huge forest in the back ground. So the Clipmap is free? where do you get that? On the 2d Disperse...not sure if I did this correct. I placed a tree. I clicked multi-replicate, and chose 30 but had 0 in the first 2 rows, and 100 in the bottom row (default). I then clicked ok and it looked like 1 tree. I clicked on 2d disperse and it did nothing. I thought above you said to not put anything in for an x movement. I did just to see and I got 30 trees.
