I looked further into how the original scene was rendered, and found out that is used Disney's Hyperion renderer. You can read more about the Hyperion renderer at this link: https://www.disneyanimation.com/technology/innovations/hyperion
In summary, the Hyperion renderer uses a ray-tracer that is capable of performing multi-bounce ray tracing calculations by utilizing a novel two-stage ray-sorting framework. This framework first sorts large ray batches to ensure coherence and then sorts ray hits. For a more detailed description of how this renderer works, check out Disney's original paper at this link: https://disney-animation.s3.amazonaws.com/uploads/production/publication_asset/70/asset/Sorted_Deferred_Shading_For_Production_Path_Tracing.pdf

This is impressive. What types of optimization considerations are the state of the art or active research areas today in rendering such scenes?
