Mod of the Week: The Elder Scrolls IV: Oblivion

Following the recent launch of an early access version of The Elder Scrolls Online, VRFocus has decided that it would be a good idea to look back to earlier days in the franchise. However, in typical VRFocus fashion, it’s not as easy as simply re-installing that Steam download, but going one-step further and adapting the videogame to work with the Oculus Rift virtual reality (VR) headset.


Unlike the growing catalogue of titles that VRFocus has covered in this Mod of the Week feature, The Elder Scrolls IV: Oblivion requires a software purchase in order to enable compatibility with the Oculus Rift headset. Tridef 3D is a stereoscopic 3D injection driver than allows videogames otherwise not offering the feature to be displayed in side-by-side mode, thus creating the illusion of depth on compatible hardware. Further than this, an experimental update for Tridef 3D allows head-tracking to also be implemented. A 14-day free trial of Tridef 3D is also available, and VRFocus fully recommends that fans of this column go ahead and get their hands on the software.


In case you haven’t done so already, download Tridef 3D from the official website, and then also the experimental Oculus Rift compatibility mod from the official forums. Full instructions of the installation of Tridef 3D are provided at the source.

The next step is to install The Elder Scrolls IV: Oblivion. If you have recently purchased the The Elder Scrolls IV: Oblivion – 5th Anniversary Edition you installation will be fully prepared for use with Tridef 3D, otherwise please ensure that the videogame is fully updated and your system restarted prior to attemtping the below process.

Bringing The Elder Scrolls IV: Oblivion from first-person to VR is a very simple process. First, load the Tridef 3D Ignition client and click ‘Add Game’. The client will automatically detect your installation (in the unlikely case that it doesn’t find The Elder Scrolls IV: Oblivion, simply select ‘Add Game Manually’).

Once detected, boot the videogame from within this client. The videogame will automatically launch in stereoscopic 3D and with headtracking in place, representative of your mouse cursor. However, it is likely that the field of vision will be reduced. In order to correct this ensure that your Num Lock is engaged and once having begun the videogame (within the dungeon area) simply press the ‘0’ key. Enter the ‘HMD Settings’ menu and manually enable ‘Force FOV’ by selecting ‘Output’. Finally, adjust ‘Output FOV’ until the edges of the display meet with the extremes of your field of vision.

NOTE: The HUD and menu systems within The Elder Scrolls IV: Oblivion have not been designed with VR in mind. You may wish to adjust the FOV until these items fit comfortably within your field of vision.
