Detailed Description

A VRV channel that represents the eyes of the HMD A Virtual Reality channel can render in a few different modes.

main ones being single channel per eye, or multiview mode where multiple views are rendered in a single pass. In the multiview instance the channels render texture becomes a Texture2DArray and each view is rendered to a different layer of the array.
