While it's just a small edit in the VMT file, many people might appreciate it if it's available as a simple addon for the game.
Copy the VPK file to ...\Steam\steamapps\common\Team Fortress 2\tf\custom\
Tell me in the comments if it works for you (both in DX8 and DX9!)
I'm planning to put this on the workshop with a few other fixes (I'll release a fix for the Professor's Speks) as one big ... thing (collection, fix, whatever you want to call it).
If there are more items which need a fix for DX8, just leave a comment here or shoot me a PM. Also, if you already made a fix, send me a PM so we can work together.
