The program saves the object data in Blitz 3D programming language object file format. I could not get the Direct X object data to load into Blender 2.49a. Blender 2.49a uses Python 2.6. I looked for the python script, but was unable to find any import scripts at all. So there is no way I can repair, or rewrite the python code.
I did send the programmer an email. I am waiting for a reply. Hopefully, since Blender is open source, a compatible exporter from the tree generator will be added.
