In /obj context, we can use Rivet Object to extract a point transform from an SOP.

How to do this in /stage? Is there something like "Rivet LOP"?

My use case is, for example, I have a curve in SOP context, and I wish the camera to move/orient along it.

It would be similar to obj level, with a follow path constraint. Although with obj, the constraint is created with chops, rather than with a lop node in /stage.

Btw, the rivet object should be considered a legacy tool. The current way to constrain objects is with constraints.

It's called Points Constraint LOP [www.sidefx.com]
