I want to make an AR foundation project but I keep getting this problem .Can someone helps me please ?
No active UnityEngine.XR.ARSubsystems.XRCameraSubsystem is available.Please ensure that a valid loader configuration exists in the XR project settings
To make it work you have to go into project settings XR Plug-in Management and select the XR plug-in providers you need for your project. Once I ticked ARCore the camera started working correctly.
