Thank you for the answer, Reggie68.

 

I now have a new problem.  This has never happened before.  I'm trying to render a scene and lux crashed and froze my machine.  I restarted and then did a cold boot.  I tried to render again, this time taking a lot of the things out of the scene.  Nothing ever shows up in the render screen, it's just black.  My efficiency is only at 17%, I'm usually at 800 to high 900's. I tried again, this time at 50% output.  Again, nothing.  I shut everything down again and reopened Daz and reloaded the scene.  This time at 50% it started to render. I terminated the render, set the output to 100% and...again I got nothing but black.  I've turned the settings up to 1000 and 1/4.  The efficiency stays down at 17%.  Not hing seems to effect it, nothing ever shows in the render screen.  I am running Lux .9 I think. 

Any ideas what is wrong?  Did I accidentally change something that would cause things to behave this way?  If so, what could it be?  Should I start using the current stable build? It's 1.0 if I remember correctly.  I've tried for several hours now and can't get this scene to render.  I created a new scene with just a naked genesis figure in it and it rendered just fine.  Any and all help would be greatly appreciated.
