When I run a simple configuration app on XR Rig and Sphere as shown below, Ray does not follow at all when I move the controllers. Once I go back to the Home screen and select the app again, Ray follows. ![image](https://us1.discourse-cdn.com/flex019/uploads/magicleap1/original/1X/e869c1eb09edc892abad3bfd77eaec84e46af7eb.png) YouTube [![](https://us1.discourse-cdn.com/flex019/uploads/magicleap1/original/1X/df69dee0743117aeb360e2a54066dc0890fa141c.jpeg "Ray on XR Rig does not work only on first startup.") ](https://www.youtube.com/watch?v=dcvzqhhH3r4) **Unity Editor version** : 2022.2.0f1 **ML2 OS version** :1.2.0 B3E.230330.11-R.044 **MLSDK version** :1.2.0 **MLSDK Unity Package version** :1.6.0 **Host OS** : (Windows/MacOS) Windows 11 Home Edition ---

Are you investigating? DevRel for Magic Leap, although the response time is quite slow. ---

running over USB? WIFI or installed your app to the device? works fine for me: sdk 1.2.0, unity 2022.2.17. I used Magic Leap Setup Tool to configure the project. ---

@tokufxug Can you try to import this in your project to perhaps fix anything that may have been missed? [Magic Leap Setup Tool | Integration | Unity Asset Store](https://assetstore.unity.com/packages/tools/integration/magic-leap-setup-tool-194780) ---

@tokufxug Can you confirm this issue? We have been unable to reproduce. ---

Currently, we are working on Remote Rendering, so we have not been able to check this project. We will create a new project and reconfirm it. We hope to have this done by the end of next week at the earliest. ---

@tokufxug I had the same issue and so did my colleagues. It was a bug in the ML Unity SDK 1.5. It doesn't happen in 1.4 and is fixed in 1.6. ---

Thanks for your reply. I thought I had originally used Magic Leap's Unity Package 1.5 and upgraded to 1.6, but it seems likely that I was not able to. I will create a new one and try it for now. ---

Thank you, @tokufxug . We expect `1.6.0` to work for you, as expected. ---

I see this problem even if I recreate the project and create it from scratch with the Magic Leap Setup Tool.
