This course covers the fundamentals of lighting for visual effects and computer graphics using HDRI images, Katana, and Renderman. It introduces key concepts like HDRI shooting and stitching, the Katana interface and node graph, basic lighting techniques in Katana including lighting with HDRI textures and light linking, and Renderman materials and shaders. The course also covers more advanced topics such as look development using lookfiles, collections and macros, adaptive rendering techniques, and scripting in Katana.
