Yup, all fixed!

Updated - all texture problems should be covered now.

Can confirm both the error prop and the purple textures. The Error only appears when I unmoubt Episode 2, but the purple stuff is there even with everything mounted: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=132841716

Not a clue about what you just said ._. I bought this because a friend at work said it'll break my minecraft habbit. And there errors are right in front of the console.

Errors? Where, precisely? Screenshots? I packed up the BM:S prop/textures, as well as the SiN textures. There's an EP1 prop, though, attached to the breenconsole.

I'm new to this stuff, but whats the error under the door opener, and the purple where the red and white lines are?

Well, I understand that part, but usually there's the issue of getting the lighting to match up, too. In every 3-D skybox tutorial I've seen, there's a definite line between the skybox and the real stuff, even if the textures and light maps line up perfectly. Except for a few spots, yours is absolutely seamless.

Really? It wasn't even a difficult trick - instead of building the skybox on guesswork and hope, I actually built the 3-D skybox as if it was part of the level's terrain. After I was satisfied with the terrain, I selected the segments of displacement to be put in the skybox and scaled them down to the usual 1/16th-scale. To line it up properly, the origin of the world was matched to the origin of the playerspace - visible in Hammer, the map's volume is a bit offset to the middle, and visible in the skybox, the terrain has a square hole where the map's volume was cut out. That reminds me, I should've compiled it with a higher skybox...

Your skills at lining up a 3-D skybox are surpassed by very few.
