Augmented Reality for UE4

[AdamHorvath]

Not yet, only landscape and portrait modes with auto focus are supported at the moment, but I put this to my todo list and will add it to later versions.

Hi Adam,

Is there any way to rotate the Camera stream OR the UI (probably the worse option) for 180°? At the moment, the device's Camera Points to the bottom, which is quite unpractical in some use cases.

Also would it be possible to use the "tap to focus" feature like in the iOS photo app or somehow else improve camera focus and resolution without decreasing the marker recognition ability?

Thank you for your help!

Hi,

I could not reproduce the issue....

Just tried with 4.13.1 and iOS 10.0.2 using iPhone 5S, and worked without any issues.
Did you get any error message in your output log ?

(I am using this free app to debug iOS errors, https://lemonjar.com/iosconsole/)

I have attached the crash report. In particular, it says: "This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data."

When you tried to reproduce the issues, did you create a new project with a new name? Because maybe, if you used the name of a previous iOS app, that app was already authorised for the camera ... just trying to guess.

Hi,

Thanks for the logs, it makes sense now ...
I removed the app from my iPhone first, and launched again from UE4 editor. It asked for permission for the first run and worked the same way as before.

I'll try with different project name.

Thanks again!

Hi rranon,

According to this link:
http://useyourloaf.com/blog/privacy-settings-in-ios-10/

seems like if you are compiling your app against the new iOS SDK 10, you need to add an extra key/value pair to your info.plist file to have camera access.
(If you are using the previous iOS 9 SDK, like I do the app will work on both iOS9 and iOS 10 without the extra key/value pair)


Add permission in info.plist file base on your error log.

NSCameraUsageDescription

<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) camera use.</string>

In UE4 ->Project settings -> iOS there is an extra PList data field, where you can add the text above.

Hey Everyone Trying to use the plugin v 1_6r2 with unreal 4.13.1 in OSX 10.11.16.
I get this..

[AdamHorvath]

Hi,

You need to compile the missing module from source.

Please follow the steps below:

1. Install xcode from apple app store
2. Launch unreal engine editor (4.10, 4.11, 4.13 or later)
3. Create a new C++ code project without starter content
4. Copy all files from SampleProject directory to your new project directory
5. In UE4 editor File -> xcode project (optional)
6. Exit from unreal engine editor
7. Launch your new project from epic launcher
8. Click on rebuild missing DLLs when prompted
9. Optional: Click on File -> Package project -> OSX

Hey Guys,

Today is my 3rd day on Unreal. So very new. I am really trying to develop something for a project at work. I need to get a Full Screen Webcam stream in Unreal. I have Unreal4.13. Can anyone please show me how to do this or have got a plugin that I can import? Please help. Any help is appreciated.

Regards,
Sameer

Hello Sameer,

Welcome to the unreal community!

If you download the free DEMO version of the plugin from UNREAL4AR.COM , you can try the basic example with webcam stream.

Instructions to get started:

I hope it helps!

Hi Adam,

thanks for looking into this. I didn't even know I was compiling using iOS 10 SDK, I thought I was using the 9 SDK ...

I can send you the logs if you tell me where I can find them, I assume they will be in the IOS Devices directory?

How is it that most of the projects here are more impressive than any games from major developers? I've seen more innovative ideas here than in the past 10 years playing games.

The log you sent me in email was the build log, but to debug run-time erros I need to see your output log.

Thanks.
