VR Look-At Trigger

Method

This node allows you to create effects based on what the VR user is looking at. The target is a cuboid region specified by the scale and position.

When the user looks at the defined space, the Current Value parameter will increase (at a rate defined by Required Hit Duration).

Use an Extractor modifier to use the Current Value to effect other parts of your scene.
