Quote - You are using Poser9? Correct ?

Yes.  I don't export to any other programs except Vue, and I'm not planning to weight-map my own figures, so I thought Poser 9 would be enough.  Now I'm wondering if I should have gone for Pro.

Quote - But yes, Poser9 does have a transparancy problem that is being worked on.
Should be OK when the SR's come out.

Thanks, that's good to know.  I thought I was going insane for awhile there.

Quote - Please, unless absolutely required. Forget IBL. Like AO, it is fake and from a period before IDL. Use bb's sphere and render with IDL.

Does IDL take less memory?

Poser 9 comes with all those IBL lights.  I thought since they came with the program they would work. 

Quote - I think with your RAM, you need an system clean up. (You did not mention your CPU)

I'm not at the computer I use for Poser right now, but according to the receipt, the CPU is an "Intel Core i7-920 processor (8MB L3 Cache 2.66GHz)"

It's a fairly new computer and not used much (basically, just for Poser and Vue).  But I'll try a cleanup when I get home.
