What is your minimum shading rate set at? Are you using a hair shader with SSS? IDL?

I had that happen with a huge scene (lots of objects and textures) when I had the min shading rate (per object) set at 0.01. Note: Poser objects and figure groups are set at 0.2 by default-but I wanted more FINE detail-so I used a script to set everything to 0.01.

Quote - I think the Poser 2014 is great but iI have now had a couple of renders finish in the normal manner but there are blocks grey blocks in the middle of the render.  I one, in addition to the grey blocks there was a band towards the bottom that did not render at all.  This one just has the missing strip.
