I tried textureless on in nQuake, but i cant turn it off. I tried editing the config but it still didnt change. Please help.
Try gl_externaltextures_world 1
in the console and then vid_restart
This will reactivate the high def 24 bit textures that comes with the nQuake package for example.
Welcome to the QuakeWorld.nu forum btw!
Don't forget to pop into the discord on discord.quake.world
to have a chat
Edit: if the above doesn't work it would be helpful to know how you enabled textureless in the first place.
