![Valve Source Code 2013 Tutorial (Episode 36): Shader Authoring Part 5 [Adding Radial Fog] @TheMaster974](https://i.ytimg.com/vi/oGmLb6r5x_U/maxresdefault.jpg)
Uploaded March 2026 | Updated September 2026, 16 hours ago
Hello everyone and welcome to a new (probably short) series of videos I do involving the source code from Valve for Half-Life 2, and some guides on how to do stuff with this code. In this episode, I showcase how to add radial fog from the 20th Anniversary update to Half-Life 2 into a Source 2013 Singleplayer or Multiplayer mod. For Singleplayer mods, the inclusion of this feature requires the compilation of shaders (which is why this video is part of the Shader Authoring set of videos). I need to give a massive thank you to @WadDeIz_Real for making the guide that I followed in the video! Keep in mind that you need to use the Perl/DirectX SDK method to compile shaders if you choose to add this, or get this video to 50 likes, then I will add the code to my GitHub! Please let me know what you think and see you for whatever I decide to do next, thanks for watching!
