Zhann-- Which is why Bryce should remove it from your hard drive when you delete the thumb. What possible use is it to be able to delete the thumb and not the texture when you can't retrieve the texture? It just makes no sense. =( Thanks, but now that I've got it figured out I can easily make my own empty preset folders. =) LSD-- Why would you ever want to export the lights? I think that Bryce handles terrains differently from, say, the way it handles spheres? Not sure about that. What's interesting is that Bryce will report the number of polygons in a scene when you load it in. So polygons are involved, somehow... they ought to be exportable to obj format.
