So blender nation had free clone troopers and my son wanted to see what 1 million looked like. I dupliverted 280,000 and slowed blender to a crawl, so I just copied an instance 10,000 times, here's only 10,000, as close as I could get to a million.... yeah I know, this movie ain't ever getting done with so many tangets, but hey, why not....
Edit: So last night I got dupliverts working and I maxed out at 280,000. I'm going to try the VBOs with the array modifier next (thanks for the input)
