I would like to know the three differences.
Is there a reference where I can find related information?

Payloads and Reference

Please have a look at the USD Terms and Concepts Read the References section first, then the Payload section and follow the performance note at the end. References are used to include other USD assets into a stage. This allows instancing of the asset. Payloads are a special kind of References where you can decide dynamically if the data itself should actually be loaded into the stage or not. This is useful for huge stages where only parts of the assets are required for a specific operation.
