Balancing sampling and Ray Depth

- [Instructor] Understanding the Arnold renderer settings…is essential to an efficient workflow.…The Arnold render settings give us a great deal of control…over how the render is processed.…Proper application of these settings…can optimize render times…by directing computing resources toward render components…that contribute most significantly to the final image.…In other words, we devote computing resources…to render components that have the most visual impact…or importance in the final render.…
