Crash!!!

 

This is a Vive Cosmos Elite with Index controllers.
Game runs fine on original Vive, and Valve Index.

This is a build-out of the project, not in-editor.

OpenXR Plugin 1.2.8
Unity 2021.1.25f1

 

Have you tried using the SteamVR OpenXR runtime rather than the Vive OpenXR runtime?

 

I did and it worked! Fantastic. I would never have thought to try this, so thank you.

This does bring up a concerning issue, though...
When I release my game, this "problem" will persist for the foreseeable future, yeah?
So I imagine that there will be a subset of my customers who will never know that this is a setting that they have to toggle in order to get the game to run. This is guaranteed to cause confusion => unhappy customers => bad reviews => a really bad time...

Is OpenXR + SteamVR going to address this? (Probably the wrong place to ask, but...)

 

Yes, this is exactly the problem I faced with Vermillion, which is why I know of it in the first place. The only solution I have now is manually selecting SteamVR OpenXR before initializing VR, so that only SteamVR OpenXR can be used. This would normally always work fine since people who bought the game on Steam would logically also have SteamVR OpenXR, but nothing is easy on PC VR. It turns out that for some reason, SteamVR OpenXR is often not registered in the list of available OpenXR runtimes, unlike Oculus, Vive, WMR, etc. So in the case that SteamVR OpenXR was not found in the list of available runtimes, I show an error message box explaining how to set SteamVR as the OpenXR runtime, exit the game, and load up my support page which again says how to do so, with screenshots. Before I did this, I reverted to the default OpenXR runtime which happened to be installed on the user's machine, but this actually led to issues, such as the one you are experiencing, or for Oculus users where they would see distorted graphics using the Oculus OpenXR runtime. Or imagine if someone has both the Cosmos and a Quest 2. The only users for who the native OpenXR runtime can be a boon is WMR.

Is it a S***ty user experience? Yes. Is it our fault? No. What a mess.

Edit: I've asked on the SteamVR community if they want to list their runtime in the registry, so it'll work behind the scene for more users. https://steamcommunity.com/app/250820/discussions/8/3200371016634050916/

 

Vermillion looks like a really great game. I'll have to pick it up. The color mixing system is fascinating.

How are you intercepting the OpenXR runtime mismatch before the player crashes? And how do you initialize XR manually?
I agree it's a bit of a mess. OpenXR is supposed to unify, not bifurcate. I'm fairly confident that things will trend toward unification eventually, though.

 

Thanks!

In the XR plug-in settings, disable Initialize on startup. Then use this repo to enumerate the available runtimes with OpenXRRuntimeJson.GetRuntimeJsonPaths(). If there's a runtime found containing "steamxr" in the name, then you set it as the system-wide default with OpenXRRuntimeJson.SetRuntimeJsonPath(). You can then use XRGeneralSettings.Instance.Manager.InitializeLoader() and XRGeneralSettings.Instance.Manager.StartSubsystems() to start VR. If it did not find the SteamVR OpenXR runtime, you can do as I do and display a message box with how to set it up, and use Process.Start() to display a support page.

Better yet, +1 my request on the Steam community so that the amount of users who see that error is reduced to those where SteamVR OpenXR is actually not installed, not simply not set as the default.

 

You are an absolute legend for sharing this. Thank you so much! I'm buying Vermillion right now as thanks (also just because it looks awesome lol).

 

Hah, thanks! Adding to that post, there used to be an error in that repo where a case mismatch on a string comparison caused it to not find SteamVR OpenXR. It's been fixed since then, so it just works now.

 

Hello, I am also having trouble with Unity VR by using a Vive Cosmos Elite. Each time when I hit the play button in unity to test my VR environment something is crashing. The first time it was unity itself crashing, causing me to loose all my unsaved changes in the "game". All the other times I tryed it the Vive Console and Steam VR are crashing. The crash starts by entering the VR environment for like a second and then the display of my glasses turns black. during that second it is possible to turn the view by turning the Heasdset and also the controllers seems to be recognized by unity.

So do you think that this is also the here described Open XR runtime problem, or might it be caused by some wrong settings I made using the unity XR toolkit?

For the Unity VR settings I followed the instructions of this tutorial on youtube, even though unity XR changed since the release of the video:

I interpreted "XR origin (VR)" as his mentioned "XR Origin (Action based)".

 

We also had a problem with the vive cosmos crashing our game VR Giants we couldn't fully fix it yet we will try that hack with the repo next.
But the quick fix was to set SteamVR as default OpenXR. The crash only happened when Viveport was set as default open xr.
