I know  why you want to do this - I have often wanted to have this kind of capability.

It sounds easy, write a script that controls Posers rendering, then input options that turn on and turn off elements on each batch render.

I'm not a python person - so I do not know the details - but I gather from many discussions about Poser batch rendering that it is not easy for some reason.

So, you save multiple versions with different cameras, and..

There is a batch render script by MarkDC out there...with certain technical cavets.

Also, there is another "commercial" solution that I forget the link? Someone?

My solution is simple.  Set up all your multiple camera angles with specific cameras on your sequence. Copy and paste multiple sequences on your timeline, and turn on anf off the cameras you need.
