Every time hit F1 in TTT the tutorial is six pages of missing textures. I own all the Valve titles and have CSS, HL2, and EP2 installed. I’m also running the Linux build.
I did search, but “tutorial and missing textures” mostly brought to guides on how to play without owning CSS… So my apologies if this has been addressed before.
First I edited /home/username/.steam/steam/SteamApps/common/GarrysMod/garrysmod/gamemodes/terrortown/gamemode/resources.lua and replaced VGUI to vgui
I had to rename the directory VGUI to lowercase. It looks like this now /home/username/.steam/steam/SteamApps/common/GarrysMod/garrysmod/gamemodes/terrortown/content/materials/vgui
Now my tutorial pages work.
