Since SH mentioned this thread earlier, I thought I'd grab some more screenshots of the various areas I could get to, and put them here. They're in the same order as in SH's screenshots in post #1:
1. 'Blank' area
Walkmesh stops just short of the big 'bridge' thing.
Area 2: With Woman
Has a female republic officer with no dialogue lurking in one corner. Area is around the corner from where area 1; walkmesh again stops by the bridge.
Area 3: Doors, Benches, Adverts
Located above areas one and two; got to from by the TSF office. Walkmesh does not extend to benches.
Note that all three areas have the same camera-clipping issues with walls as modder-built areas.
Hope that's useful.
