Hi i am havin’ some troubles.
When ever i downloads a bg i do as the Readme says i should, and then when i am starting gmod, the original bg is still there.

I don’t see the problem in what i am doin’ makin’ it not work? What could it be?

there are two backgrounds in garrysmod\materials\console there is a normal (background01.vtf) and a widescreen (background01_widescreen.vtf) these are the default textures for your background, it is possible you are getting backgrounds while its using the other. Try replacing both.

… By copying the reg. then name the copy (and if needed, rename the original) to the name needed
