I just convinced my friend to buy Garrys Mod. After getting it he tried to play some servers and got error messages everywhere and purple checker textures. We tried uninstalling etc, and we realized he didn’t have HL2 or CSS installed. He has 2 Steam accounts, one with HL2 and all those games and one with all HL1 games. He downloaded Garrys Mod to the HL1 account.
Is there anything he can do to get the textures and models working. What if he signed into his other account and installed Half Life 2 and CSS? Would that work?
Just to clarify, he has TF2 on his account, which he just told me says fits the requirements, so what is the problem with it?
