Disclaimer: Some things are completely unusable with this method as they need mouse input. You cannot use the cams nor the power monitor using UEVR, which makes Night 5 impossible to beat without very weirdly switching between VR and PC

You will first need to download the UEVR Injector tool, found >> here <<

After downloading UEVR, right click the downloaded .zip folder and click Extract All (Or if you're using WinRAR or 7zip, choose Extract To UEVR")

After UEVR is extracted, make sure you have your VR on and open. If you have a Quest, you will need to connect to your PC via Quest Link, Virtual Desktop, or Steam Link, and then run SteamVR before proceeding. This guide will not show you how to do that.

Once you're in VR, you can take your headset off and continue on your PC for now.

Now open UEVRInjector.exe, and then open TNaF.

After both programs are open, go into UEVR, and set everything to how it is in the following image;

After that, click Inject. Do not put your VR headset back on yet. You will see a new window open up on top of TNaF. The following images are the best settings I've found;

After you have set these settings, you can put on your VR headset, but you will need to use your mouse to click Play. After that, you can begin playing! You will also need to switch to using your mouse for anything UI related, like pausing, the cameras, and the power monitor.

Once you're in the game, click both joysticks at the same time to close the menu that will be in your face

Again, the game is mostly unbeatable like this. An official VR port will be coming eventually, it is recommended to wait for that. But if you really want to experience it in VR right now, this is how.
