I see, you're talking about the base models that came with poser, and the original Kids 4 base model. Thanks hborre.  My team leader is still offline for now, once I've heard from him I'll post here regarding the HDRI settings he's looking for.

For now I've attempted to setup the render settings.  As far as I can tell, I needed to setup the regular render settings, and also the movie render settings. I'm not sure whether or not one affects the other. Here are the screenshots, look ok to you so far?
