uCatcher adds a technical receiver to a USD scene. Separate color and alpha accumulation modes, thresholding, projector restriction and scene transforms make it useful for isolating contributions that need to be rendered or composited separately.

When to use it

Shadow or reflection catcher layers
Projection receivers
Technical masks and holdout-style passes
Restricting a receiver to one Projector ID
Separating catcher content into its own USD stage
