I have recently upgraded to P7, having not used Poser since P4 days.  I'm running into a weird problem, and I was hoping the collective experience of Renderosity might point me in the direction of a solution.

Back then I had an extensive purchased library of characters and props, many of which have no recent versions that I've found.  However, I am having severe problems with Firefly, as the attached render shows!

Note how the beam has bulged, and even encased the metal hook on the side.  The P4 renderer has actually done a pretty good job.  Unfortunately, for production reasons, I need to use Firefly.

This doesn't happen with all props - just some.

Any ideas would be appreciated.

I have logged a case with E-Frontier, but as their site doesn't even seem to have any P7 resources yet, I'm not hopeful.
