It's the next stage in the NBA 2K League's rapid growth. Brendan Donohue (Managing Director of the NBA 2K League) described the league's growth to me recently in the phone as "transformational".

Interestingly enough, it was initially triggered by some petty payback from another member of the staff here, but, as it turned out it was a great choice. Last week, my fellow coworker, Mod WhatsBotting was on his way to work on a crisp and clear morning. To help the Earth avoid getting too hot, Mod WhatsBotting likes to ride public transport. On his way back to the bus stop, he drives past the local elementary schools.

Only black screen appeared

SDK 9.8
September 12, 2021 - 10:21pm #1


I built an AR application with Unity and Vuforia a month ago. And the app run well for some days. 

But after about a month,

when I open the app, only black screen appeared.(I didn't edit anything. I just have used the app.)



So, I tried the reason and I found it. After ARCore update of my devices, it is not working. 

Vuforia Ground plane and new version of Android ARCore cause the problem.

How can I solve this problem? Please help me.

Ground Plane not Functioning in Samsung Galaxy S21

September 9, 2021 - 2:09pm #1


Just curious if anyone has had issues with getting ground plane tracking to function on their Galaxy S21 device. The ground plane is detected when using the webcam. Just when I build it out to the device nothing, not even the ground plane image is detected. I had an older device a Galaxy S8 and functioned perfectly fine on that device. 


Device OS: Android 11

Unity Version: 2019.4.12f1

Vuforia Version: 8.1.12

Topic solved

Hello, I made an AR APP  and its working ground plane . used for  Unity 2020.3.13f1 and Vuforia 9.8.5 . Unity build  to APK is working well(Redmi note 8 pro, Redmi note 10 pro both android version 11, and Samsung note 8 android version 9 all working )  . But Unity integrated a native  android app (Android studio) and built an APK to not work. Camera opened and sent me an error message " Unsupported device "((Redmi note 8 pro, Redmi note 10 pro had this message,  but  Samsung note 8 working) . I tried the Vuforia version up to 10.1 with no difference. How to fix it.

Ground plane and image target

July 28, 2021 - 9:22am #1

Hi all, what I'd need to do is use an image target (the image target itself will be on the ground) to set where the AR models will spawn and then lock the models to the ground using the ground plane, as extended tracking isn't accurate enough (at least for my hardware limitations). Years ago I found something that helped quite a bit on the forums but I can't fix it to work with new vuforia versions.

Thank you and sorry for my broken english.

Edit: using latest Unity and Vuforia versions.

Ground Plane pricing

April 20, 2021 - 5:21am #1


We are developing an app that uses both Image Targets and Ground Plane. We have purchased a license for the Image Target. We have also read in this forum that the Ground Plane functionality can be deployed for free, even in a commercial app. Could you kindly confirm that Ground Plane is free for use since we do not see any details for that in the pricing section. 

Thanks and Regards,
