Greetings, all. I'm fairly new to Vue; I purchased Vue 4 last fall. I've been using Bryce 3/4/5 for a couple of years now. I'm also pretty new to Poser, but find the two programs work well together. I have learned a lot reading through the forum archive here.
I have a rather confusing problem in the terrain editor. If I import a picture (jpg or bmp) to use as the terrain, I get a very weird jaggy effect in the main editor window, although the picture import window has the terrain looking good.

The result is that the terrain looks really terrible when I render it in the main Vue windows. Any advice?
