I get black not so nice looking areas where there is supposed to be some reflection when rendered in Poser 2010. But when rendered in Poser pro (can't remember if it is 8 or 9 :P ) it does just fine. What do I need to have the render settings in Poser 2010 to make it render right?

Poser 8 render with same lighting and same render settings.

I could be wrong about this, but see if gamma correction is checked for rendering in 2010.  If it is, uncheck it and try a render without it.

I don't like using gamma correction so I always have it unchecked.

I get those occasionally when I use Indirect Lighting. I noticed a few things about them.

• If you save the render as a TIF or a PNG, the alpha layer will contain a hole at those black spots.
• Uncheck the Reflection_Lite_Mult on all materials that does not need them. My best guess is that the lighting is being multiplied too much.
• If possable, do not use the velvet material node with Indirect Lighting. I heard from bagginsbill that the velvet material node has some issue.
• I also noticed that they occur less frequently in Poser Pro 2010 32 bit compared to Poser Pro 2010 64 bit.
• They will change with a different camera position. In a few instances, they will change when you render the image again.
• Most annoying, it occurs in Poser Pro 2012.

I hope my observations will help. I have deleted many renders with this problem.

And it occurs in Poser 8, like, when you said, indirect lighting is involvled in the render. I have the same problem from time to time. I even had a render where the problem occured in two different places when I changed the render size.

I don't have an answer for how to correct it (except not using indirect lighting?). I just wanted you to know that it is not specific to your machine...
