Unity 5.1.2P2 - VR Crash - 100% Of The Time

Hi all, I just upgraded to Unity 5.1.2P2 and my VR project crashes on play or on build every time. I made a brand new project, didn't change/add anything and found out that just by checking "VR Supported" in the Player Settings and then hitting play makes Unity crash every time with a "Read from location 00000008 caused an access violation" in the error.log generated.

I tried using Unity 5.1.2 (official, not patch) and did the same, new project, clicked "VR Supported", hit play and all was good. I did notice something a little odd though, when clicking "VR Supported" in 5.1.2, this dialog popped up:

"Changing editor vr device

Changing active VR API requires reloading all graphics objects, it might take a while"

But this never came up in 5.1.2P2 and both versions of Unity were set to the default PC platform.

Anyone else encountering something like this?

I should also note that I do not have an Oculus Rift connected, only developing for Gear VR. Also I tried re-installing Unity 5.1.2P2 again. Also 5.1.2P1 worked fine.

 

Similar errors happening on Mac version (building for Gear VR)

 

Hopefully we hear something on this as I'd like to take advantage of the new VR updates.

 

*BUMP* I've had the same problem when I press play. Without warning Unity will crash and throw the following:

Unity.exe caused an Access Violation (0xc0000005)
in module Unity.exe at 0033:41230586.

I am also using Unity 5.1.2P2

 

Same here, hard crash when hitting play in editor with VR enabled...5.1.2p2
- gtx980 -win8

 

Cool, thanks for the update

 

Thank you Ed, super appreciate the update... I thought I was doing something wrong!

 

Don't suppose we can get a rough ETA on this?

Need to tell a client whether it's going to be days, weeks or months ideally .

 

@timsk: I'd imagine it would be sometime this week, they tend to do weekly patches from my past experience.

 

Awesome, thanks for the update!

 

Cool, glad this is getting fixed! Just ran into that problem today.

Also, if you want patch release updates, just subscribe to the RSS feeds. It's super handy.

Confirming fixed for me in 5.1.2p3 (64 bit windows).

 

Yep, 5.1.2P3 is working great, thanks!

 

I just upgraded to 5.1.2P3 but it's still crashing for me. Are you by any chance using version 0.6.0 or older of the runtime?

I've just discovered that 0.6.1, which I'm using is supposedly unstable with one of the newer Nvidia drivers. But from what I can gather, it's been a while since that became apparent so they might have fixed whatever was causing it in a later driver.

 

Hey, I'm using 0.6.0.1 on the runtime, is that what you meant? I'm only developing on Gear VR, not rift.

 

Sorry, yes. The current version of the runtime. 0.6.0.1.
As soon as I updated, Unity crashes whenever I start up a scene with VR enabled.
As far as GearVR goes, I figured the root of the problem might lie in a similar area.

 

Hmm, odd. Are you trying a brand new project to test it out? If not, try making a new project, make sure you're using 5.1.2P3 and click VR Supported then click play. That "should" work.

 

It's an old project that started out pre-5.0. We used to depend on the old OVR package until the update, at which point we cleared everything for the native support.
Before I updated to the new runtime and updated the graphics driver, the Oculus ran just fine. Albeit, the framerate was hampered between 68 - 80 frames per second, even in an empty scene. Which is the main reason I updated the project as well as the runtime.

I'll try creating a fresh project like you say though to see if the problem re-emerges, thanks.

 

Make sure the whole OVR directory is gone and everything in the Plugins directory EXCEPT for your sig file at Plugins/Android/assets.

 

I have dual native VR camera setup for having content in left or right eye. But whenever I try it, it crashes instandly. I don't know if this is related to the problem you described or that it's related to native VR dual setup. Can you check that?
I accidently made a topic on wrong forum about it. Asked for a move, but I posted a bug case number.

Hello,

Same thing happening to me with Unity 5.1.2f1 with platform set to iOS.

I've noticed in the ProjectSettings/ProjectSettings.asset file, the flag virtualRealitySupported is set to one even when switching to iOS platform (doesn't make sense) and even if I first switch to, let's say, PC, turn the VR support off and then switch back to iOS.

My fix was to manually edit the ProjectSettings.asset file by setting virtualRealitySupported: 0 and this solved the issue

 

Just started having this problem.

everything was working fine only 10-20 mins ago.

as soon as i hit play/build it crashes.

Virtual reality is supported and im doing this project for the DK2..

Below is attached dump file.

OVRPlugin.dll caused an Access Violation (0xc0000005)

in module OVRPlugin.dll at 0033:f7ed3a3c.

 

I have a similar problem and could really use your help.

Mac OSX
Unity Personal 5.1.2f1
Building for GearVR
Trying to play one of the OVR examples in the editor and it crashes every time.

 

Unity.exe caused an Access Violation (0xc0000005)
in module Unity.exe at 0033:41230586.

in 5.2.1

 

Similar problem here but with even more weird behaviour. If I restart the computer first 2-3 times the app will crash after 3-5 seconds but after that it runs well as long the computer is not turned off ....
