skyboxes are only usable if you are NOT using ANY portals (either player placed or game placed)
otherwise you have to use regular flat sky textures (which aren't that bad)
any comments on the actual map so far?

If you WERE to make it so the player could escape, maybe you could include 1 or 2 outside levels. Perhaps something caused an explosion, and the lab was reduced to rubble. That would provide lots of surfaces to portal on, and you could also start some fires as well. Say a player got too far away from a fire source, they would start taking damage cause of the cold or something like that. Tell me if you think this is stupid or not -_-.
Lol are these my Aperture Science cargo containers?
Anyway looks awesome so far, I love portal maps with more then normal test chambers.
