Problem solved :D

Even though im still not sure why the gamma/lut causes problems. It seems to be possible to fix it by setting all materials when loaded to a custom gamma of 1.0 Whether that is a rule of thumb or only if you are using jpgs i don't know. But if anyone can explain it, i would appreciate it as its always good to know why you have to do something :D

But here is a Poser render with 10% intensity and no Gamma correction.
