Ok, thx again. I will try and write you back.

I tried this and still no results. But i might not be doing the right thing.

Here is what i tried:

Found the c++ file @ PROJECT_PATH/Plugins/ARToolkitPlugin/Source/ARToolkitPlugin/Private/ARToolkitDevice.cpp
Searched for “-flipv” and replaced with “-noflipv” in the above cpp file.
Saved it.
Returned to unreal and refresh the xcode project.
Build and Launched on iPad.

Still didn’t work.

Do I need to make a brand new unreal project and copy the contents of the commercial zip again. Then change the cpp file then rebuild it? It seems their must be an easier way.

Best,

Hi,
is the re method to place AR behind a real object ?

AdamHorvath · April 26, 2016, 9:54am

I’ve sent you email with details. I hope it’s been already resolved by now.

AdamHorvath · April 26, 2016, 9:55am

Not with a normal webcamera. You need a depth sensor like the Kinect for this.

hii, i just wanna to try this amazing plugin. but unfortunately, i seems can’t open the demo project (i use unreal engine 4.9.2 and unreal engine 4.11.2)?? there is a warning that they can’t find the ARToolkit Module

Thx, i was thinking about this.

Hi . Do you have an update on the ETA for 2D barcode support? Thanks!

AdamHorvath · April 27, 2016, 7:54am

Hi ,

I am still working on some updates for v1.5. The good news is that the 2D barcode part is ready.
if you want to beta test it please send me an email to info@unreal4ar.com.

Hi ,

just getting started with your plugin (looks great!) but… just to avoid confusion, you may want to change the dates in your changelog.txt to 2016

Cheers

Hi ,

I’ve been trying to get your plugin to work on Android but have been running into issues. I followed all of the steps in your documentation but keep getting errors when trying to to Android. Below is a snippet of the errors in the output log.

I should note that it does work when running for windows but launching to android does not.

@dsenter: looks like you didn’t copy over the AndroidJNI.cpp but instead renamed the old one and left it in the project. So now you have two cpp files trying to define the same methods and classes, causing all kinds of conflicts… and your errors. Move the old files out of the project and then it should work.

AdamHorvath · April 28, 2016, 1:10pm

Oppps, I see. Thank you!

anonymous_user_b28d45881 · May 3, 2016, 6:53am

Has anyone got the commercial version of the plugin to work on 4.11.2?

Daniel-1981 · May 3, 2016, 9:01am

@iLLogic808 - yes i got it to work…

dsenter · May 3, 2016, 1:13pm

I was able to get it working on 4.11.2. I compiled from source though so that I could deploy to android.

guo13080319157 · May 4, 2016, 11:19am

Hi,
I’ve bought your plugin with PERSONAL license. But when I lanch on my iPhone. It gives some error and won’t let me lanch. I’m using UE4.11.1 and Xcode7.3 on Mac OS X10.11.1, my iOS version is 9.3

AdamHorvath · May 4, 2016, 1:47pm

Can you please send your full build log ?

anonymous_user_4757195d · May 5, 2016, 5:55am

Hello .

Before buying a commercial version of the feeling is not bad, Then you will join the object recognition?
