I pushed the magic Make Art button before I went to bed last night, to get an idea of what a render I am on a hard deadline for would look like, finished. Eight and a half hours of snoozage later, I wake up to the image enclosed. 
And I am nonplussed, as the same wires showed up fine in the preview renders. 
I did "rig" the wires in PoseRay as recommended in the fora. 
Is there a workaround for this? 
thx for any help :-)
