There are models of people, cans and other 3D Objects that you can used to populate a scene without greatly overtaxing your computer power. To use these item, you musty install the plug-in for 3D Studio Max and then use the Archvison Content Manager (ACM) to locate the RPC files you have access to. After that, you have the ability to place these items in your scene. The process for doing so is quite straightforward.
