[OpenVR] Cannot have two instances of the same project open at once (build and editor)
Steps to reproduce:
1. Download and open attached project "vr-test.zip"
2. Make sure the VR mode is on
3. Build standalone project w/ "Example" scene
4. Run the said project
5. Play the project in editor
Actual result: Standalone just quits
Expected: Standalone pauses or disables VR mode
Note: This makes local multiplayer testing impossible if multiple instances are used
Tested and reproduced on:
Windows 10
Unity 5.4.1p3, 5.5.0b5
HTC Vive

This is still a problem in 2018.2 ..Has anyone sifted through the OpenVR /SteamVR packages to try and circumvent this?

For anyone being in this awkward spot of Unity crashing while developing a VR multiplayer game:
You can run multiple instances, where one instance has no VR enabled and cannot be controlled by the HMD input.
1. Edit > Project Settings > Player Settings
2. In XR-Settings click the [+] Plus icon under the List "Virtual Reality SDKs", add "None" to it
3. Build the game and navigate to the freshly built .exe file
4. Either create a batch script or two shortcut links where one startup parameter is
-vrmode None
and the other (depending on your VR device)
-vrmode OpenVR
Although this is a rather ugly solution, you can still run two instances this way - just without the second one being controllable by the HMD itself.
I hope this helps and I hope they are going to fix this in the future by claiming the VR-Device as soon as the window is focussed.

Same issue in 2018.1. This is very very annoying. Adds many hours to VR multiplayer development time. This is not an issue in Unreal Engine....
