You can also fix your GMOD Textures by purchasing Counter Strike Source. The upside Is the fix Is extremely easy, and you only need to download 2 files which are free. It can be frustrating trying to play a game of deathrun or prophunt and not being able to tell exactly which route you should take, or where the sneaky hiding bottle Is. You may be seeing Error Signs, and purple/pink and black squares.
If you’ve played Garry’s Mod, chances are you have come across texture Issues (missing textures).
