ARCore Extensions for Unity's AR Foundation supports both
version 4
and
version 5
of AR Foundation. To upgrade your existing AR project to AR Foundation 5.x from
AR Foundation 4.x, follow these steps:
Ensure that the Packages/manifest.json contains these versions for the
following packages:
"dependencies": {
-- other dependencies --
"com.google.ar.core.arfoundation.extensions": "https://github.com/google-ar/arcore-unity-extensions.git#arf5",
"com.unity.xr.arcore": "5.0.5",
"com.unity.xr.arfoundation": "5.0.5",
"com.unity.xr.arkit": "5.0.5",
-- other dependencies --
}
AR Foundation 5.x requires the Input System package
due to a dependency on TrackedPoseDriver.
The ARCore Extensions Sample Scenes require the legacy input module.
To support both the Input System package and the older Input Manager,
in Project Settings > Player > Other Settings set Active Input
Handling to Both.
