Hi Oshyan,
I ran the correction '5' with success. Thank you for resetting where it was needed. I will use this file as a reference for all future builds.
One question however; although the trees are too small in this instance to make any difference – but, how do you keep the trees from going up the vertical of the distant mesa? I expect it is adjustments to the altitude and slope constraints (I think this is how I got off the track in the first place). I would expect that minimizing each of these settings would keep the trees off of the vertical surfaces.
Another issue is the stark contrast of the tree foliage. I think this is an Xfrog problem – not one of the Terragen program. I've been adjusting the color somewhat in an effort to soften the effect of the trees looking as though they were stamped on the image.
In all, I am very happy with what you've done here. I will also be working with the '7' correction you have made. I'll keep you apprised of my progress. Thanks again Oshyan.
Bob
