It must be the perspective, MuddyGrub, it's the only thing I can think of. Wonder if there is any way to fix it other than post (which I won't try tonight since I am now very very snokkered). The vines were fun. I used the same technique I posted a while back when discussing hedges. Except, with the vines, I just worked with front and side distance renders instead of a top view altitude render. That way, I had an image of my building, with windows and such, and then I could draw my vine terrains in on a layer on top of that.

Could be worse, could be raining.
