Positional Tracking stop when switch to VR Mode

Hi,

I am working with the ground plane feature, the lasts vuforia updates seems that make it more stable, in my case with a Galaxy S7, the detection and tracking works better than before.

But I notice that when I start (on Unity) on non VR mode and switch to VR mode (with Cardboard SDK selected) the Vuforia log show me that stop positional tracking and smart terrain and start the tracker again, so I lose the original tracking on non VR mode.

That does not happen when I select Vuforia SDK on XR, and do all the VR stuff only with Vuforia.

I preffer Cardboard SDK just cause the is easy to configure the Stereo Device/Box just with a QR Code, in my case VR BOX that I cant select from Vuforia SDK

Anyone else with this?

Best regards

Mariano
