So since yesterday, after the recent Team Fortress 2 update, a lot of my textures for variouse Source games have become pitch black with the exception of the model for the gun my character is holding, the odd patch of ground and the models for other players.
Does anyone know how to fix this? I have already tried using the delete local game content option on steam and downloding the games again but I suspect the textures are stored in a different place because it didn't seem to work.
