Thanks for everyone's advice.  I did a forum search but didn't see that link WandW.  Thanks for pointing it out.  I think I'll stick with SR2 for now as I don't want to create any more problems.  

The render splotches on the hair and the circular artifacts on the skin were solved by turning off irradiance caching which makes for a very clean render but it does take a very long time.

The hair artifact due to subdividing was "solved" by changing the skinning method back to Poser Traditional and not subdividing it at all within Poser.  I exported it and subdivided it in modo then imported it back into Poser and rendered it.  So this will be my workaround for a bit.

Cheers,

Jackie
