Stereoscopic (SideBySide) at runtime

How to render SideBySide at runtime ?
I found this code snippet in the docs:

   private void Start()
   {
      StartCoroutine(LoadDevice("Split"));
   }

   private IEnumerator LoadDevice(string newDevice)
   {
      if (string.Compare(XRSettings.loadedDeviceName, newDevice, true) != 0)
      {
         XRSettings.LoadDeviceByName(newDevice);
         yield return null;
         XRSettings.enabled = true;
      }
   }

This works pretty well in “Play Mode”, but not in the builded EXE File. Isn’t it possible to set this up for a build ? My aim is to toggle between “None” and “Split” as loaded device. Does anyone has an idea ?

It would appear the token is currently “split” not “Split”. (I know it’s capitalized in the documentation sample you used.) I added VR support for Mock HMD (split) and None to a player and was able to switch between them with the following script.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR;

public class ModeToggle : MonoBehaviour
{
    public string[] devices;
    public int devIdx;


    // Use this for initialization
    void Start()
    {
        devices = XRSettings.supportedDevices;
        LoadDevice(0);
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
            LoadDevice(devIdx + 1);
    }

    private void LoadDevice( int idx )
    {
        devIdx = idx % devices.Length;
        StartCoroutine(LoadDevice(devices[devIdx]));
    }

    private IEnumerator LoadDevice(string newDevice)
    {
        if (string.Compare(XRSettings.loadedDeviceName, newDevice, true) != 0)
        {
            Debug.Log("Loading: " + newDevice );

            XRSettings.LoadDeviceByName(newDevice);
            yield return null;
            XRSettings.enabled = true;
        }
    }
}

Thanks Mike for your answer. Finally, I got my script working after seeing your solution. The problem was that I did not add “Split Stereo (non head-mounted device)” to the supported devices. This setting is not available through “Player Settings” in Unity 2017.4, so i had to add it programatically through an editor script.

PlayerSettings.virtualRealitySupported = true;

UnityEditorInternal.VR.VREditor.SetVREnabledDevicesOnTargetGroup(BuildTargetGroup.Standalone, new string[] { "none", "split" });

After adding “split” it works fine.
