First the rendering question so I don't forget to mention it:

Carrara for some reason is absolutely refusing to let me render from any of the main cameras.  Keeps creating new cameras which are my only options to render from, if I delete one it just makes another.  Have I mistakenly checked some obscure setting that is causing this?

Now lighting.  In Poser if I want a dark part of a room, I create a black light.  Here when I create a black light it doesn't really make the room look any darker at all.  Spot light is not working because the edges are Way too crisp and I want a look as if a light is shining in through an open door.  At the same time I want to add a level of drama to the scene with darkness closing in around the subject.

It's important that I don't place the light right on top of the subjects because then I lose my doorway shadows.

It's been noted also that my lighting around the subjects is too even.  Is there a way to avoid even lighting or to add depth mapped shadows in Carrara?

hoping I explained and asked this all correctly.  If you feel you might be able to help me but need clarity - please ask - this is an important project to me.

Thank you.
