A low-quality RT render showing a view from up near the roof. I like this.

Yes, it needs entrances/doors such as you have in mind, although for my purposes these need only be cosmetic. If you add behind-the-scenes things such as prep rooms, etc., I would prefer it if they were done as separate props - no point in always loading the scene with geometry that isn't always used.

Lighting... I would like to see an optional set of modelled spotlights mounted up on the 'beams', or whatever they are called, together with a corresponding Poser light set to load scene lights within the modelled spotlights. Perhaps a few different lighting presets.

By the way, where is the ground level supposed to be? The default load position is with ground level more or less at the top of the arena seating area... which is okay.

Time to sleep.. more later.
