So far I've only tried a few PZ3 imports into Vue 6 Inf.  I did change Vue6 to point to Poser 7; in fact it had Poser 7 in the list, already.  But I pointed it to the Poser 7 exe.

I imported Ben2 and the first render went fine.  After that, things became very sluggish, and finally froze, and the program crashed.  

When importing the Poser PZ3, I chose to use/keep the Poser engine for shaders, from that dialog box that pops up during the import.  This is the purpose of having these two programs work together; if I have to give that up to get a PZ3 successfully imported, well...... That may not be the cause of the problem here, but I'm just saying...

Running on a Pentium Dual Core machine w/ 2 GB RAM in WinXP SP2.  This machine is new, and I intend to use it strictly for Poser/Vue, plus related utilities & Photoshop. 

Has anyone else had any such a problem?
