Hi andrew,

There is really something fishy with modo here, I was able to get rid of some of the glitches by lowering the angle to 3, and using 'avoid smaller than' 0.1 to reduce the polycount ... but it reveals other reflection problem on the knob.



This only append once the reflection is activated, the shading (with specular) is looking right. If I triple the object inside modo, everything is rendering fine.

I've never seen something like that until now, but it's really weird.

I'm opening a bug report on luxo beta board right now, and I'll keep you inform.
