steamvr logoToday Valve has released an update for SteamVR, the virtual reality mode for the popular game distribution service. The update enables Oculus Rift DK2 support for Half-Life 2 and the Steam Big Picture mode. Here’s a detailed guide to get it working.

Valve has been an early supporter of Oculus VR and virtual reality. Their popular shooter Team Fortress 2 (2007) was one of the first existing games to be updated with Oculus Rift support. Half-Life 2 (2004), arguably one of the greatest games ever made, was also updated with Oculus Rift support early on, way back in May, 2013.

In January, 2014, Valve released a beta version of SteamVR, a mode for the company’s massively popular Steam game distribution client that allows it to be viewed in a virtual reality version of ‘Big Picture Mode’.

Today Valve has updated SteamVR to work with the latest Oculus SDK 0.4.1. This brings support for the Oculus Rift DK2 for the first time and also enables positional tracking, the much lauded feature that provides a more immersive and comfortable virtual reality experience. Half-Life 2’s virtual reality implementation relies on SteamVR, and now that the package has been updated, it too works with the Oculus Rift DK2. If you own Half-Life 2 and the DK2, there’s pretty much no reason to not drop what you are doing right now and get your head into that world. Excuse me… I’ll be back in about an hour.

Optional Tip: Increase the Size of the Positional  Tracking Volume

For some reason the positional tracking volume inside of Half-Life 2 is artificially limited. Here’s how to fix it.

  • Enable the game console in Half-Life 2 by selecting Options, then the ‘Keyboard’ tab, ‘Advanced’ button, and select ‘Enable developer console’. Press the tilde key (~) anywhere in the game to launch the developer console.
  • In the developer console type ‘vr_translation_limit 100’.

Here are a few things to try if you’re having trouble:

  • Ensure you are running the latest Oculus Runtime and that your DK2 has the latest firmware installed. Here’s a guide on updating the firmware (which also shows where to get the latest Runtime).
  • Make sure you have your DK2 turned on and set to Extended Mode. You can change from Direct Mode to Extended by double-clicking the Oculus eye icon in the Windows System Tray and selecting ‘Rift Display Mode’. Mac doesn’t currently support Direct Mode so it should bet set to Extended by default.
  • If positional tracking isn’t working, first make sure that the blue light on the positional tracking camera is turning on when you launch SteamVR or activate VR mode in Half-Life 2. If it isn’t turning on, right-click on the Oculus eye icon in the Windows System Tray and select ‘Configuration Utility.’ Then in the menu, click Tools > Advanced > Restart Service, click ‘Yes’ on the following prompt. Quit SteamVR or Half-Life 2 and restart Steam.
