Hello and Good morning.
i’m currently a student at a Local university in Malaysia,Bachelor of Computer Science
I am required to do a Final Year project with what i have learn throughout the university.i challenge myself creating something i don’t learn in class which is multimedia.

my idea is combining “Gamer’s perspective” into architectural world,which is using Unreal Engine for the platform.
i am currently studying Unreal Engine and slowly understanding the basic.
but i have trouble and would like to ask you for help.

1)how do you create VR with Unreal Engine?i have read the documentation,but im still not quite understand it
2)i don’t have a VR headset(Oculus Rift or HTC Vive).so i was wondering,in Unreal Engine,how to make android phone to become the VR headset
.i got Chinese VR Headset and my phone have gyroscope.i have researched a little and some say,“if the phone have gyroscope,that’s mean it is VR capable”.
3)how to connect android phone as a vr headset for UE VR test?

i have try a roundabout solution.
Phone mirroring computer screen<–work
Multiplying screen for a set of eyes and concave the display<–still not found a software that could do it

The easiest cheapest and most compatible VR is Google Cardboard. UE4 has cardboard support (using an SDK that requires at least Android version 4.4 from memory).

Most of the documentation is tailored towards Google Daydream unfortunately however you can still use most of it for cardboard development (it has no motion controller obviously). If you have a Pixel phone then you can get a Daydream device - else your Chinese headset will support Cardboard.

UE4 doc: https://docs.unrealengine.com/latest/INT/Platforms/GoogleVR/

Google unreal integration doc: Quickstart for Google VR SDK for Unreal with Android  |  Google Developers

Also note if you plan on doing Android VR then you have to take into account the performance considerations - even the high end phones will struggle to run the high end engine features. Make sure to read through the mobile development doc section to see what features and material types are supported: Mobile Game Development | Unreal Engine Documentation

Hope this helps you get started with what you have! :slight_smile:

my phone is Asus Zenfone 3(ZE552KL).it is a mid range phone.
if i lowered the spec in the UE design and quality,do you think it can run 30fps average?

i have tried the roundabout solution and the average fps it can give is around 25.i haven’t tried with a lower resolution yet.

another question,does unreal engine capable to display 2 view at the same time to imitate VR like?

i am really appreciate the link you given.i will look over it and try some of them.
thanks again for the link :smiley:

You will be able to get 30FPS through optimizing. But for VR you really need 60 fps btw to prevent getting sick. Use the GoogleVR plugin as per to doc to get split screen as it creates the 3d effect for you and you shouldn’t do it on android another way :wink: it’s actually very easy to do and works well
