fyi: Unreal 4 Cardboard
Hi all,
I tried doing the simpleHMD setup on iOS. To report, it worked out fine. I also setup the look around controls using tilt, and they too worked out fine.
Now when m setting up the controls, its all messed up.
I tried doing a simple line trace by channel, and it went all wonky, pointing in directions unknown.
Can anyone suggest what could be done on this front?
Hmm, shouldn’t this just be the direction vector of the camera?
I wouldn’t go off of Input Motion, as this seems to be all over the place. Specifically, it even differs between iOS, UDK Remote and Android.
Best,
Minxes
You can now test several real-time demo applications with the Google Cardboard on your Android device (Android 5).

Nice! Is there any way you can provide .apks so we just install and run the games (so it’s usable without ADB) ?
That’s possible already. Just unzip the (zip) archive and copy the included APK onto your smartphone. Then install it from there.
Cardboard on iOS
Hi folks. I’m over here after viewing the discussion on Google Cardboard on iOS support - XR Development - Epic Developer Community Forums
I lost a few days to other projects and problems with mobile provisioning, but I’m back. Before I try to do anything fancy, I just want to test the pipeline from Unreal to Cardboard on iOS. I’d love any help you can offer.
- I can build a non-Unreal app in Xcode and launch it on my iOS phone
- I can create a First Person Blueprint Template (no code) and launch it on iOS either from Mac Unreal or Windows Unreal
- If I disable all the VR plugins and enable SimpleHMD, I can run that same project on Mac or Win with dual cameras
- If I enable the SimpleHMD plugin and then try to run that same Blueprint-only project on the phone again, I can’t.
Do I need to find the SimpleHMD source and build it? I have minimal experience understanding where things break in Unreal. The relevant part of my log is at the bottom of this post.
Ultimately, my goal would be to use the Cardboard SDK in a new plugin built on SimpleHMD (if I can find the source and figure out how to do that), because there are variants of Cardboard and it’d be nice to use the QR code configuration.
I also tried using the Rift template mitchemmc created and offered to the community here (VR Game Template - XR Development - Epic Developer Community Forums), disabling the Rift plugin and enabling the SimpleHMD plugin, but no luck deploying to the iOS phone either, although again, I could preview with two cameras in Windows just fine.
Log of my most recent attempt deploying from Mac Unreal to the phone with SimpleHMD plugin enabled:

Hi Nick,
Are those fixes already shipped? May be any update about Cardboard SDK integrations status is available?
Quick update from the horses mouth:
Doesn’t look like 4.11 is going to get Cardboard support.
Regards,
Minxies
There are a few fixes we need to make to the mobile rendering pipeline to fix up the support that would allow you to do user VR on Android. We plan on performing that work over the next few weeks. After that, you should be able to make it work with Google Cardboard
http://imgupp.com/img/1447454487.jpg
Wow, I think I speak for all when I say we eagerly await!
So are you working on just the rendering or more than that?
Super excited about this.

Hi all,
So I think I read all the threads about cardboard vr in android … and it seems it’s still not working properly.
Or am I wrong and I missed something ?
Does anyone have a working solution for a correct motion control in phones ?
Hi guys,
We decided to open our own adaptation of Simple HMD plugin to use as Cardboard while official support is not implemented by Epic/Google
Hope it will be helpful for you 
Hi Zulman
I have followed your instruction but get the following error;
“Plugin “UE4Cardboard” failed to load because module “UE4Cardboard” could not be found.”
Do you why this is and how to sort it out ?
Thanks
Hi Nick,
I am new in this field. Do we have any approach to render a VR on our android phone and display it with google cardboard. Please let me know! Thank you!
Great news, official Google Cardboard support seems to be coming to the engine!
See here: https://www.reddit.com/r/oculus/comments/4iq3rq/androidvr_likely_to_be_announced_next_week_at/
It looks like the existence of a new “AndroidVR” (Google Cardboard) plugin was leaked in the breakdown of the latest 4.12 Preview 3 release notes.
This note has since been pulled.
It is slated that the Google Cardboard SDK will be relaunched as AndroidVR this coming Google IO.
From the looks of it, AndroidVR looks to be a collaboration of sort between Epic Games and Google.
Best,
Minxies
Some different unofficial workarounds to try out for now:
-
“Unreal Engine 4 supports all the major devices and you don’t need to perform any hassle to setup your project for VR. Just make sure that the correct plugins are loaded for your HMD under Edit > Plugins.”
From there find “Virtual Reality” category fromenable “basic HMD” plugin (stereo quality is quite bad)
After that “Play game as” Menu in Unreal Engine will have non-grayed out Virtual Reality (stereo) mode (where you normally can choose Play In Editor or Stand Alone mode, etc) -
Community Plugin for Cardboard (not sure if its updated/works)
https://github.com/ -
https://forums.unrealengine.com/

that is all just about “stereo” mode, controlling using sensors is not supported, probably.
