What I do really is a several step thing. For large things like distopia, I look at where in a block I want to try a render. this means loading it first and just scoping out stuff. also for the co-ordinates for where in pose space they are. once I have a good ide of a location I close all that and set up a scene with the people. I load pose dres and light them (with spotlights) them I load the large item and then move the item to where I want. So I am moving as littel as possible. taking the mountain to vicky. Then I switch to full tracking mode in poser to line things of for the fine pose of the large thing. I do it that way since vicky and all the stuff hanging off her is tricky to move. and since spotlights stay where you set them as opposed to area lights that back up to account for the largest thing in the poser document.
