The only other thing that I can see would be how the lights are currently being written out. At the moment, they are all given the same name of default which seems to give visual errors on how the polygons of figures are rendered. I guess I'm trying to say that most of them appear to be massive black blocks instead of smooth shadows; but, if you give them all separate names like Light 1, Light 2, and etc the shadows render smoothly. Though, technically, that might be a problem with how Lux itself interprets the lights from the exporter.

Can you please post yout *.lxl file?
