Issues fixed
Black and purple textures and giant red models

- You can download the Garry's Mod content specified above as an addon. However, you'll have to find the download site on your own since it contains copyrighted content.
Game crashes at title screen
Use the +connect 1:1 command line argument[citation needed]
|
Notes
- When the game opens, it will take you to a
Connecting to Server screen. After a few seconds it should dissappear and take you to the title screen. It will then freeze for a few seconds, then function normally.
- Sometimes you may need to press Alt+Tab ↹ then go back into the game for this to work.
|
Hosting a listen server
Start listen server[citation needed]
|
- To host a server while playing, one must be able to forward ports and enter a console command.
- Forward the ports 27015 and 27005
- Enter
sv_lan 0 in the console
- Press "Play Multiplayer" and select a map
- Others should now be able to join
Notes
- In order for your server to show up on the server list, you must change
sv_region to a value corresponding to your region.
|
Could not load library client (Linux)
Additional Libraries[citation needed]
|
- Install the appropiate lib32 gconf package (libgconf-2-4:i386 for debian-based systems, libgconf-2.i386 for rpm-based distros, and lib32-gconf on the AUR for arch users).
|
Game changes microphone gain at launch
Modify configuration file[3]
|
- Go to the configuration file(s) location.
- Open
config.cfg .
- Find the line
voice_mixer_volume , it should be near the bottom of the file. If the line doesn't exist you may create it.
- Set the value to whatever you prefer your mic volume to be, I set mine to
.5 which translates to 50% gain.
Notes
- Removing the line does not work.
- This will set a fixed value, and might not be a solution for people who are using dynamic gain which Windows (or other applications) automatically adjusts.
|
Disable exclusive control of microphone (Windows)[4]
|
- Right click on the speaker icon located at the tray bar.
- Select Recording devices.
- Double click on your microphone in the newly opened window.
- Go to Advanced and untick Allow applications to take exclusive control of this device.
Notes
- Most applications ignores this, and many users are reporting that it isn't working.
