I think you'd like vue. YOu can import all your poser scenes very easilly then add things. Or one thing I do is take something like stonemason's scenes, duplicate them in vue, then past them (it's as easy as copy and paste) and place them rotated next to each other to create the effect of big cities. Here's one I did with andi 3d stuff. It's a picture I did a long time ago with an older version of vue. Love esther
