Augmented Reality for UE4

[Moonmana]

Ok, here it is:
I created brand new project and copied the plugin into it, everything according to the tutorial for full version and it has the same problem.
Here is the apk, you can install it using the bat file and see the app doesn't work on any android device:
https://ufile.io/aelc6
Please keep in mind it doesn't matter if it's single apk or apk + obb, the result is the same.

Ok, so you have uploaded your project it without the .obb file. I told you it won't work ...
Can you upload your project with the .obb file ? I can't test without it.

The .bat file is required only for testing, not for publishing your project on google play.

The only modification you need to make before uploading to the store is to change one line:

In SampleProject\Plugins\ARToolkitPlugin\Source\ARToolkitPlugin\ARToolkitPlugin_APL.xml there is a line:

String obbPath = Environment.getExternalStorageDirectory() + "/obb/";

Try to change it to:

String obbPath = Environment.getExternalStorageDirectory() + "/Android/obb/";

Can you please try the demo on the store ?
https://play.google.com/store/apps/d...unreal4ar.demo

I've uploaded it using the same method, and tested with many samsung / lg phones, and worked without any issues.

Try to change it to:
String obbPath = Environment.getExternalStorageDirectory() + "/Android/obb/";

That would save so much time if the line would be in your documentation as well as the requirement to use obb.

Thank you, it works now.

Here are the brief results of the testing:
There are 3 things which affect on the ability to init camera:
1. If you ever launched the app using launch button in unreal editor
2. If "Package game data inside apk" checkbox is checked
3. If the line described above is changed

So if you launch the app using unreal editor it copies artoolkit folder to sdcard folder and then doesn't matter if you checked "package game data inside apk" or not, the app will work, doesn't matter if you installed it using bat file or through the store.
If you didn't launch and the folder is not in the sdcard folder then if the checkbox is checked the app won't work. However if the checkbox is NOT checked it will work only being installed through the bat file and not through the appstore. And to make it work through the appstore the ARToolkitPlugin_APL.xml should be changed as described above.

Please add these 2 things to your manual, to save other people time. Thank you!

Thanks for your feedback! I am glad it's working now. I've updated the manual accordingly.

Hi, there.

1 quick and maybe dummy question.

in the documentation u said

"d. iOS

You will need a Mac computer to package your code project for IOS devices!"

Still needed a mac computer?

[AdamHorvath]

Hi,

As far as I know macOS / xCode is required to compile any C++ code for iOS.

Hey Adam, just sent you a message about an issue with my billing and account, could you please look into it?

Hello,

I've sent you an answer in email.

Hello Adam,
First, I want to thank you for your work that allows us to develop augmented reality games with unreal engine. I bought your plugin yesterday and I have a problem to deploy it on an Iphone 5c. I can deploy blank cpp projects so my certificates work. I am at your disposal if you have any questions.

Hello,

I am sure it's not plugin related, but something regarding your provision / certificate files.

Check out the following lines from your log:

Seems like UE4 can't find your certificate file. Can you please check it ?

Hey!

I've got a quick question:

Is it possible to modify the display output on a mobile device in a way that the camera feed is shown as SBS monoscopic VR?
This way it would be possible to take a phone + Google Cardboard and cheaply demo mixed reality with some tracked surfaces.

As the output would be monoscopic (only one camera, thus not double the image processing) the performance shouldn't suffer a great deal
I imagine.
Monoscopic of course has obvious drawbacks, I'm just interested in the overall doability of this use case.
Another deal breaker would be if the image quality was just too bad to bear which would again depend on the present camera.

Kind regards

Hello,

You can get the web camera feed as a texture, and use it on two planes to mimic side by side video. It's definitely doable but, the video feed won't be stereo.

Hello I checked th Demo version. GetMarketMatrix input accepts 0-63 (AR_MATRIX_CODE_3×3). Is there any way to use AR_MATRIX_CODE_6×6 even it is not recommended ?
