In this comprehensive workshop by Graham Cunningham, you will be taken through the entire process of lighting and compositing a cinematic shot using Maya, Katana, Arnold, and Nuke. This is an advanced course that builds on the Introduction to Katana workshop by Taeyoung Kim.  This 4-hour workshop begins with setting up OCIO for ACEScg, importing and preparing assets in Maya and Arnold, creating a layout and shot camera, managing your .tx files and color spaces, and details how to convert materials to MaterialX, and export everything to Arnold USD.  Next, in Katana, you’ll discover how to update the shot template, create some new macros, prepare Interactive render filters, and set up AOVs for multi-channel EXR output. You’ll see how to import your USD assets, optimize your scene, go through the lighting setup, and create and modify HDRI light textures (in a quick excursion to Nuke).  From there, the workflow proceeds to the creation of render passes, how to manage visibility and sampling, and render image sequences to disk using Katana batch commands. As the last step, Graham jumps into Nuke, where he shows how to assemble the render passes, split out light AOVs, adjust light colors and intensities. You’ll also explore how to add atmosphere using volume/fog renders and WorldP data, how to add fog FX using stock footage on 3D cards, as well as how to use cryptomattes to fine-tune results, add glow, lensflare, film grain, and apply a final color grade.
