Jeff - this is just a stab in the dark but do you have the 'Seperate Process' box checked in the General Preferences? The only time I got memory problems on rendering was when it wasn't.

Other than this I can only think that Poser might be passing on scene elements that it's File Search can't find for some reason, but you'd usually get a popup for that kind of thing.

Is this happening with old scenes made in  previous versions opened in P8?
