Augmented Reality for UE4

[AdamHorvath]

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

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

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

Hi David,

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 Adam,

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 Adam,

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 launch 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.

[MENTION=35218]dsenter[/MENTION]: 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.

Hi Adam,

Oppps, I see. Thank you! :-)

[iLLogic808]

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

[Daniel-1981]

[MENTION=109747]iLLogic808[/MENTION] - yes i got it to work...

[dsenter]

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

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

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

Hello Adam.

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