Just a quick answer here, as you do not give a lot of details.

In Poserpro2010, or better since poserPor2010, I only use ONE infinite light.

And BB"s free env Sfere.

Mostly I have to reduce the light as the sfere is kind of "all around", and self iluminating.

But ; more questions??

HOW do you render?

in process?

In a separate process?

How many treats?

Bucket size?

Background renders?

Using the quemanager?

Boy I have a lot of questions for this one..........
