Today, all of a sudden, the bumps are coming out the wrong way around (no idea why). So tried setting a negative value on the bumpmap in C4D, and noticed that the exporter skips the export of the bumpmap entirely if it is negative.
EDIT - figured out why the bumps looked odd - left a zero out of the bumpsampledistance parameter.

The model is from 3DRender.com (I'm not that good at modelling), cleaned up, modified, and textured by me in Cinema 4D and then rendered in LuxRender. There are a LOT of light sources. The render took quite some time (40+ hours on an 8 core machine) and still didn't quite get to noiseless in a couple of areas (front display case being one of them). But here it is:

Why did that happen?

I went over the http://www.luxrender.net/wiki/index.php ... ile_format page before 0.6 and fixed a lot. There may be some issues left however, and I'll see if I can fix those.
Since the main (0.7) branch is in such heavy flux, I suggest you keep targeting 0.6 for now, at least until the 0.7 branch settles down. The missing quad shape I mentioned above for instance is in the 0.7 branch... if you use the 0.6 release version of LuxRender the quad shape is still there and it will work fine.
I'll let you know when I've gone over the scene file format page.
