here's the bump problem
no matter what setting I use, (even a bump intensity of 1) I get theses plotchy noisy artifacts once bumps are turned on
tweaking/cleaning the bump maps source didn't help
darth_shader: no regathering on the previous image (didn't improve much) and just one skysystem (skylight+sun)
filtering of the solution set to 2
rendering of solution + direct illumination (raytraced shadows)

That's the same problem I have with the sponza scene ...
Anyone that has a sollution for it?
I've tried everything ... (exept regathering, seems like my PC can't handle that, VIZ4 hangs when I try to render with it ...)
And if you ask me, Lightwave scores best in that content.
Man, what a results !
Super realistic !
Not even 1 VIZ4 image in the contest where I think : "Hmmm, is that a photo or a CG image?"
I hope Autodesk fixes this soon!
