I think the problem is with the lights somewhere matcreator.

At least thats what I think the problem is for me.

I had the same problem recently with Poser 5.

For some reason when you have lots of lights, and lots of shadows Poser doesn't like to render them.

I'm pretty much stuck using a maximum of six maybe seven lights.  Anymore than that and Poser likes to just sit there and do nothing, or it tells me it's finished rendering after only rendering a part of the image.
