It''s that dream again...
Back in college, out of hours, out of uniform, barefoot, alone...
Any moment now, some Chthonic monster is going to erupt from locker, office or air-con duct...
And me without halberd or flame-thrower !!
Seriously, this is ($$) ''Faculty for Poser and DS'' by coflek-gnorg, found on Rendo. Not free, so I''ll not link. There''s three versions: ''Neat'', ''Trashed'' and ''Trashed with Crawling Death''...
This is the ''Poser-Friendly'' model, there''s a ''DS-Friendly'' bundled. All I''ve done is dim Poser''s own lights, turn off ''ground'', and super-dial the Hallway''s ''ceiling light'' material to, eventually, 3. No ambient mask required. I began with 10, but found the luminaire panels had enough area to ''wash out'' the scene...
Adjusted camera angle and lighting via a couple of quickie test-renders, sent job to networked ''Box'' as Superfly, 64 pixel-samples.
Slightly annoying is the way those doors are *not* ''free-standing'' but part of their frame and wall. I spent an hour trying to un-pick one with TurboCAD, discovered they''re also only the visible face, like a theatre''s painted ''flat''. Disappointed...
When I''ve dressed the young lady to suit, I''ll send in the monsters...
Nice one Nik, I hope the janitor's around somewhere, to lend a hand against the creepy crawlers
