I've found a converter which claims to be able to convert levels from Unreal Tournament into VRML/X3D files. I've got a fair bit of experience with the UT level editor, so if I can make this work it will save me a lot of work in building virtual worlds for the lab. But I've downloaded the demo converted worlds and when I try to load the .py files into Vizard it tells me that there's an error loading them. The same files seem to work fine in 3D viewers such as CosmoPlayer. I realize this is kind of a far-out-there 3rd party software problem, but if someone has an idea on how I need to load these to make them work I'd really appreciate it.
The converter and demo files can be found here:
