Strogino Cs Portal Gmod: No Steam User Hot

One approach is to use a non-Steam version of GMod, which can connect to the Strogino CS Portal servers. This method requires:

Edit garrysmod/cfg/mount.cfg and add:

"mountcfg"
"cstrike" "C:\\Counter-Strike Source\\cstrike"
    "portal" "C:\\Portal\\portal"

Note: For no‑Steam, paths may be ignored; instead use the addon folder method.

Create the following folder structure:

C:\GMod\garrysmod\addons\my_css_content\
    └── materials\
    └── models\
    └── sounds\
C:\GMod\garrysmod\addons\my_portal_content

└── materials

└── models

└── particles

Then copy the respective .vpk contents or raw folders from CS:S’s cstrike and Portal’s portal into these addon folders.
