Hi bwtr -- I like to think of the scene size as the dimensions of the virtual 'stage' that I'm 'shooting' on -- you have your choice of a 30 inch stage for objects and closeups, a 30 foot stage for rooms, people, etc., and a 3000 foot stage for landscapes, space scenes, etc. Objects come into each stage at their fixed virtual size -- you may have to resize things so that they are in scale with each other. For example, Michael 2 comes into a medium scene at right about 6 feet tall; in a small scene at just over 72 inches tall -- about the same height either way. The only difference is whether he's standing in a 30 inch stage or a 30 foot stage. I believe the stage size will also impact scene effects like atmosphere, etc., and how fast you can move the camera through the area. Now, my only problem with this is that I created a lot of stuff previously without being accurate about the scale -- but it's fairly easy to resize things using the Motion tab...
