There are a lot of ways of doing this as long as you are making a render and not an animation. (you can also do this with an animation but it's a more time consumint) Here's one way of doing this is, Have as many figures as you can render and put their expressions you want. Render them with the background either one within poser background props, or just a background that you may have allready. Save that render as a background. Keep in mind that these figures are deeper into the background, so they will be a little smaller than the forgound figures on your next render you will do. Also it would be good to stagger these charatures a little further back and forth so they don't look like they are in a straight line across. Depending on how many people you are wanting to use. If you are wanting a whole lot of charitures, then use say 3 or 4 of the Lowest Poly figures way in the background with another 2 or 3 P4 fighures in front of them with better expressions than the lo poly figures. Next import that first rendered background as your guide and final render, and for placement when you get your big guns out Mike and Vicky 1,2 or 3, if you want to use Vicky 3 or Mike 3 just use the fewest morphs that you can allow on those charitures, mostly expressions and a single body shape when needed. This will help you get the largest number of charitures that your computer system can handle to make that last render. Render the whole batch and you will have quite a few people with a background with your main charitures in the forground. I had made an animation with 18 charitures with a computer that was not as fast as I have now, using Mike and Vicky 1 or 2, along with 13 low Polly charitures that were animated along with my forgound animated Charituers all in the same scene with a background Picture I made in Vue 3, that worked out great. One last thing, you don't have to just have to have these charatures comming at you, you can have them sideways or at an angle. Just use the same format described with the angle you are wanting to use. Hope that helps.
