Hey, I'm pretty new to terragen 2. I've been working on a scene with snow capped mountains, and an imported f-22 model from Maya. The import worked flawlessly, and everything is going great except for my object populations! I cannot for the life of me seem to be able to make an object population that is anything but a square. i would like to have trees everywhere leading up to where the mountains turn into rock, and was hoping that i could just do it with height constraints or some such, but i have had zero luck thus far and it appears that in order to achieve the desired effect as my knowledge stands i would need numerous populations lined up around the edge of where i want the trees to cut off and i'd still probably end up with a hard line!... Any help is appreciated!
