Okay, I've only made very little progress on the geometry exporter itself so far, just fixed a little bug in the triangulation code. But at least I can export scenes and get renders out now, so I'm able to see what my code does.

The somewhat butchered version of ADP's script I've come up with is attached. Like bagginsbill, I've ripped out all the world transformations. I've also done a lot of fiddling with the code that transforms the lights, some of which may be useful, but most of which is probably rubbish. And I've added some boilerplate code to make Lux accept the whole thing as a scene file.
