thanks , that helped allready a lot! it worked (and had to delete the whole folder of kitedemo too). It does package, but this is still red in the log:

LogTemp: IPP ERROR: Could not find provision directory ‘C:\Users\rober\AppData\Local/Apple Computer/MobileDevice/Provisioning Profiles/’.
Weird i dont use any apple devices, so something is allready set in the BP.

if the distribution tab is checked for google playstore, then the package failes btw. But that might be a whole different problem nothing to do with your AR template

Thank you, you beautiful soul :slight_smile:

Hi ! Is it possible to compile it to an iOS device directly from Windows UE4? Thanks!

996

I don’t think so. You will need a mac to do that.

997

Hello, I hoped you could help me with these problems when packaging, I get about 500 in the Output log, they are all relating to the ARToolKitBaseAdvanced and custom pawns I have made based on the sample classes

I am using engine version 4.18.3 and plugin version 1.7, however I did compile for engine 4.18. At least I think I did…

998

Hi, and. I am getting ‘webcam init error’ with unreal4.18.3 with iPhone 7, I have added the string on additional PList. Please let me know if there is any fix for that. Thanks in advance.

999

Hello,

Plugin version 1.7 is not working with with 4.18.3. You will need the latest 1.10 version. Please send me your order id to info@unreal4ar.com and I’ll send you a new download link for the updated version.

1000

Can you please send me your device log ?

1001

I am not sure how to generate device log if there isn’t a crash, but if I just look at the device output from Xcode, here is what I find odd on each tick event

Hi, and! Is it possible to get marker position on the screen (not in 3D space) from blueprint? Thanks!

1003

Hi,

You can do that with ProjectWorldToScreen node

Hi I am still having this trouble running the sample with an iOS device and would love to have any useful input

iPhone 7 (iOS 11.2), UNREAL 4.18.3

Hi,

Possible solution here:

1007

Ahhh, been looking for the solution for a few days. It will be helpful if you specify it somewhere on the website.

1009

Actually it is there: "Editor binary version for Windows / OSX"

I am glad it’s working now!

Not able to package or on IOS device. Opened the blueprints and have several errors. ARToolkit variable not found, Get Camera Frame Variable not found, and several others pertaining to ARToolkit. Can someone give me some step by step instructions on how to install this properly or how I can adjust the blueprint to get rid of the errors?

1011

Hello,

Check out the iOS section:
http://ar.uplugins.com/getting-started-full-version/

First you need to compile the plugin using xCode. It’s an automatic process.
After that you can use the blueprint nodes, and package for iOS.

Hello ,
We are trying to make an augmented reality app on mobile (Android 5.1 and newer).
With unreal 4.18.3, we are using the plugin unreal4AR commercial version.

When we add the plugin to our project and it on mobile phone, it crashes instantly on the phone without any error in the logs.
Everything works until we actually add the plugin to the project, the build succeeds, but when the app opens it just crashes.

What can we do to find where the problem comes from?

Hello,

Try to disable the following plugins:

  • OnlineSubsystemNull
  • OnlineSubsystemUtils
  • OnlineSubsystemGooglePlay
  • Android Media Player
