Moving on from there, he shows some of the basic controls for lights, materials and mesh shapes. After that Robert demonstrates how Arnold can render a few more things than just polygons by jumping into working with volumes and rendering curves. The final lesson before starting on the cover image is the creation of extra render passes (AOVs) and using them inside of Nuke. He finishes the series by lighting a stylized scene in which he starts with a basic lighting setup and then moves onto shading and final renders before bringing them into Nuke for a final composite. Within the last lesson Robert goes over a few quick tips for saving time and creating a unique look with utility nodes and more.
