I think my level size is getting way out of hand.

When I would build and run it before the 6.4 version, I could actually get it to load, but since I upgraded to 6.4, it only loads some of the entities and then freezes.

Anywho, when I try to run the wmb from my work directory, it tells me it can't and that the nexus size is like 2700. ACK! I know that's huge.

I need some good advice on how to cut down on the nexus size without throwing out my work. Namely:

1. The recommendation to cut my level into separate "chunks (like on a grid) and build them separately and then combine them into the final, big level, is intriguing, and I could use some tips on how to do that. As it is now, my level is a mix of wed architecture, entities, models and sprites. Re-positioning them all would be, to a great extent, too much trouble. Any shortcuts available? Can I retain positioning somehow?

2. Is there a way yet to export wmp architecture to mdl while retaining texture information? I've been building a lot of my models in Blender, and I'm getting quite comfortable with that and the excellent exporter and model reducer some folks wrote... In any case, if I could also export models in their current position and then combine them into one model (say a group of plants staggered on a sloping hill), that would be helpful, yes?

3. My level is *big* geographically, given that most of it is architecture. And I don't have much choice on this because it's based on a real public building with lots of open space both inside and surrounding it, and it has a lot of windows. I can't have parts of the map that should be visible not visible, and I can't have separate "levels" having to load up because movement has to be seamless as this is for an interactive walk-through that is expected to get a lot of use (no wait times allowed). Any advice on how to accomplish this? Would the "chunking" of my level as described above (along a grid) help with this?

Any and all advice would be much appreciated. At this point I need to be able to run my level just to see if my doors are working in it properly, and I can't even do that. Please help me undo my newbie mistakes!

Thanks...
