for a tutorial using Mod Tool Pro 7.5 I want to distribute a couple of trees on a terrain.
This is what I have so far:

I duplicated the trees randomly using a script. Is there a better way? Something like a tree brush I haven't found yet?
Is there a good way to align the trees with the ground without having to move each tree separately?
I tried the Align Objects-tool but that seems to align only the bounding boxes of the objects.
Thanks for your help, it is much appreciated
