The ThinkingWithPortals Map Showcasing Thread
As for that water reflection effect - Jose is absolutly right, there is an application named caustic generator that creates a bunch of pictures that you can use to create an animated texture and apply it as overlay on your brush.[/quote]
So you made an animated Overlay? Okay, thanks ^^

Looks great 
I've always wondered what a night-time map would look like.
But perhaps you'd like to experiment with a bluer ambient light? The night sky looks great, but I feel the lighting betrays it a little.
Yep!
Of course 
Yes.

If already, aperture should just teleport cubes to the ground instead of into the droppers, but nooo.....
They have all the quantum tunneling devices, (Portals, sendificators...) but, they use bulky tubes.
Well, you can move a tube around when you're rebuilding a test chamber, but portals fizzle if moved. They'd need to keep restarting the portal.
They didn't fizzle when you had to cut pipes leading to that huge neurotoxin tube in Portal 2
True, but try it in any other map and it won't work. I was stuck for a long time there because I had expected the mechanics to stay consistent.
