Chrome Aperture
Now, this is almost certainly not the right section for this post, but sod it.
For the last week and a bit, my cave textures have looked like they've been nicked from the future episode of Spongebob. Take a look here: (Note, this is from my recent map release, but this is an issue in retail and other custom maps) http://steamcommunity.com/sharedfiles/f ... d=94266869 A couple of retail maps: http://i.imgur.com/n0XN5.jpg http://cloud.steampowered.com/ugc/90209 ... 7EF697463/
I've verified the cache, updated my drivers, reseated my GPU, even upgraded to Windows 8 since this has happened, and it still happens (For the record, I'm on a nVidia GTX560 Ti).
It isn't just me having the issue however. Many people on the Steam Forums are complaining of Chromed cave textures (namely blendrockdirt_tunnel3b and blendrockdirt_tunnel3a) throughout Chapter 6 and onward. Basically, if these textures appear, they're chrome. Supposedly, dropping down to anything under the High shader option fixes the issue (though obviously this looks like utter shite on a big monitor :3). Another solution is disabling specular reflections alltogether, though this is a pretty impractical fix really.
I've tried digging through the VMT file to see if I can solve the issue, though it seems that the original VMTs in the VPK takes priority no matter what I do with the GameInfo.txt (before someone asks, I've tried /Materials in Portal2, Portal2_DLC1 and Portal2_DLC2 to no avail.)
Does anyone have a solution for this? People have reported this to Valve, and since it only came when Portal 2 updated a week and a bit ago I'd expect it not to be too long before they fix it (though it took them ages to patch Left 4 Dead when that had texture issues...)

ugh... Everytime they update PETI they seem to break something else.
Why put all that effort into PTI anyway? Hammer is much superior.
Of course, they're buried under an avalanche of companion cubes and roller coasters, but that's beside the point.
