transform::ClampedLookAtPorthole

Limits the rotational range of a LookAt to a porthole on a sphere’s surface.

On this page	Inputs Outputs
Since	21.0

This subgraph adds additional functionality to transform::LookAt to limit the range of the resultant LookAt to a circular porthole on the surface of a sphere. It also computes local UV coordinates that describe the offset of the resultant LookAt within the porthole’s available range.
