"The OP has stated In many threads that he has Apple Final cut pro, which support Alpha Channels.
Poser will render single figures with alpha channels that can be composited in FCP to make "crowds".
But this workflow would require prudent planning"

Uhhhh. If you actually read some of my threads , this is one of my techniques i use now.
But i use it for background crowds, i may animate them with automatic walks so it's simple. 

But for main characters, if i have 4 interacting in my scene, then i need these all to be in my scene.

But anyways, thanks everybody. 
I'm ok now

ps. It's not finalcut Pro. it's final cut express( 99 dolalrs)
