Question

Where is PassthroughCameraAccess?

Hi,

I updated the Meta XR Core SDK and related SDKs from 74 to 83. Then the Meta XR Core SDK package shows a compilation error. It seems to be missing a class or something needed by the MR Utility Kit. Did other required packages increase?

Unity 6000.0.55f1

Occulus XR Package 4.5.2
