Looks like a sign for a stripper bar.I want one!!!
Since no one said it yet, it's the icon for one of P-body's gestures, but I can't begin to imagine how it got there...
Yep; nothing special compiled/zipped/pakratted or whatever.
It's just something that randomly showed up apparently.
First I thought Djinn was pulling a trick on me... But no; this is really random :O.
Shouldn't the person who has played about 4000 maps in his life check his portal2/portal2/materials folder for a recently added texture? I wouldn't be surprised if this was just used in a coop map.
Yeah, wipe out your materials and addons folder. It looks like a VGUI material that's being rendered where it shouldn't. Try it on a stock map.
As said it only happened once. Probably due do a glitch in the new graphical beta driver. Maybe it's really just a glitch that the driver rendered a wrong object due to whatever, I don't deny that.
Whatever it is, it's not a "hidden message".
Yeah I don't know. Maybe I'm too much of a cynic, or I know way too much about how 3D engines work. Maybe I just hate when people try to find "hidden" things in games that aren't really there to begin with. But my instant and immediate thought was a renderer glitch, something completely and unquestionably unintended. If the erroring texture was something like text it would be easy to dismiss it as a very obvious hoax. But the fact that it was some completely random VGUI material made it instantly clear it's just a random renderer bug.
