So I'm playing with material proxies experimenting with team coloring and I just wanted to point out that VALVe left out a brace ( "}" ) in the file "models\props_lab\Tank_Glass001_dx60.vmt" - it's in the source materials GCF.

Anyway, if you're getting some error talking about this particular file (or perhaps another) - like "KeyValues Error: RecursiveLoadFromBuffer: got EOF instead of keyname" etc etc - it might be a typo or missing character in the file!

So uh, just extract that file into the correct directory structure in your local mod directory and fix it (add the brace) to make it work.
