Okay, the bloating stopped, but I still have the weird "rounded corner"issues with the older model.

Gonna pull in the new model and see what that does.

BTW - I have it divided now into 3 "sections" I guess you could call it.
1 - The Arena below, hallways, the 2 large side monitors above the doors, the seating and railings - everything you could "walk" on.
2 - The monitors suspended over the arena.
3 - The whole ceiling section with the girders and lights, etc.

By having only 1 of these at a time  - say, just the flooring section so you can set up your characters and basic lighting - greatly reduced the polycount and things seem to work much faster. Then you can add the later sections at the last minute IF you are going to need them at all, or if you want something like the shadows you see in mine.
