**Unity Editor version** : 2022.3.22f1  
**ML2 OS version** : 1.6.0  
**Unity SDK version** : 2.1.0  
**Host OS** : Windows  
**OpenXR** : 1.10.0  
**XR Interaction Toolkit** : 3.0.1

I've created a new Unity project.  
Imported the packages: ML, OpenXR, XR Interaction Toolkit, and Samples.

Every interaction works just fine in the sample scenes, except pinching.  
I can't grab objects or do other pinch-related actions.  
There were no error messages either.

Upon pinching, the hovered object and the fingers get a blue highlight, and the pinch indicator appears, but nothing happens when I move my hands.

Am I missing something? Should it work?

Thanks for the help.

**SOLVED**

The problem lies within the provided _XRI Default Input Actions_ asset of the XRI's Start Assets sample.

You have to add the OpenXR _pinchValue_ binding to the _XRI Left Interaction_'s (and _XRI Right Interaction_'s) _Select Value_ action:

_{LeftHand}/pinchValue_  
(_{RightHand}/pinchValue_)

Save the asset and pinching will work again.

And unfortunately, you can't just use the _MagicLeapOpenXRInput_ asset with the XRI because all the XRI actions will break.

(Note: XRI = XR Interaction Toolkit)
