> Quote - How many threads are you using and what bucketsize?

Hello,
I use bucket size 32 or 64, and 4 threads (I have 4 cores).

This happened only once, but another time I had this problem:

(The pink area was transparent in the render, and these 3 big black spots.
The same image rendered OK another time).

As these are just 1 out of 20 renders, and PoserPro2010 is perfectly stable
otherwise, I wonder if they are due to hardware (but I had never any issue with
another program or another Poser version.)

Best regards,
  Michael
