Just a tip that comes in handy:

Using Primitives as Parent Targets:
When constructing a complex scene with many props and figures, use primitives as parent targets for groups of objects and figures you may need to move or rotate as one. This is especially handy if you really like the lighting you've got set up, but want to render the scene from different views - Keep the camera where it is and just rotate the primitive and you're done.

Load the primitive, label it as something memorable (I use "Target"),put it at -1 y axis (Optional - just so it's below the ground plane), uncheck everything except for "visible", parent groups of objects to it as needed, move the primitive when you wish to move/rotate these objects. Individual parented objects can be rescaled or moved as needed. You can also just scale the parent "Target" object to scale everything at once and move the parent target wherever or however you wish to move the entire scene or groups of objects.

(Note: This can be done with lights, as well, though a couple of changes may be needed in preview rendering options in order to make the light projectors render there properly, so they can be seen and won't interfere with rendering, since they'll likely take on some rendering attributes of the primitive. May depend on version, though - I haven't used that trick in recent versions of Poser, though there are some lighting products here that use that trick or similar ones.)
