Petr, I was thinking about some kind of preview/viewer program for the blender export script. A few minutes ago I found the AT-AT model with a viewer script on your forum. This seems to be a perfect framework for what I want to do. Now that we have thinbundle, I can try to get this working. I just have to find out, how to start an external app from the blender API.

Again, thanks for the script.

Btw. does someone know a little conversion utility (run form the command line) for images? It should be free to use of course. Then I could copy the textures on the fly to and convert them while I'm at it.
