1. In Poser 8 you sort of can by choosing under Camera controls the light you'd like to look thru. I'm not sure how accurate it is ;). I can't remember if it can be done in Poser 7 ;).

2. Can't do this as far as I know.

3. You can do this by going to File/Import/Poser Document and chosing another .pz3 scene file if you wish. I know it can be done in Poser 8 and I believe it could be done in P7.
