Katana is a powerful lighting and look-development application used across the globe by many studios, both large and small. Learning Katana independently or setting up a project from scratch can bring about many challenges. This 4-hour workshop by Senior Lighting & Look Dev TD Taeyoung Kim walks through all the basics of Katana and explains how to create a lighting template that can be used for your own shots.
This detailed workshop covers how to create simple yet useful tools inside Katana that will improve your workflow. Using the lighting template that is created through the workshop, Taeyoung then lights a simple shot and renders it out with AOVs using Arnold. He also shares his industry tips for setting up accurate lighting using an HDRi and a backplate. Using renders from one of the shots, Taeyoung then shares how to work with the AOVs and pull everything together in Nuke.
By completing this workshop, you will develop a sound understanding of how to work in Katana as well as how to render images that you can take into any compositing software.
The project files supplied with this workshop include all the .macro files and assets demonstrated throughout the training videos.

Mastering basic node operations is crucial for working efficiently in Katana. Tony encourages practice with these tasks, as they form the foundation for complex workflows. By building a simple rendered scene from scratch, beginners gain hands-on experience and understand how elements connect to produce a final render.
Duration: 13m 58s
This lesson introduces building a professional lighting template in Katana to streamline the rendering workflow. Tony provides a framework covering asset import to final render output, emphasizing efficiency. By creating this template, artists focus on creative lighting rather than technical infrastructure.
Duration: 4m 40s
Understanding the three grouping methods in Katana is essential for organizing complex networks. Tony shows that each serves a different purpose: Group for organization, Group Merge for same-type nodes, and Group Stack for sequential chains. This knowledge prepares users for building complex lighting templates.
Duration: 5m 2s
By creating a logical node structure, the template provides an efficient workflow for importing assets and managing render settings. Tony demonstrates how a modular approach allows for easy navigation and modification, setting the stage for building custom macros.
Duration: 10m 42s
Creating macros streamlines repetitive tasks and promotes consistency. By building reusable node groups, artists eliminate tedious setup work. Tony uses a macro for subdivision surface conversion as a practical example of leveraging the expression system to build production-ready tools.
Duration: 9m 53s
Combining switch nodes and user parameters lets users build intelligent tools that adapt based on selections. Tony focuses on how macros serve as starting points that can be expanded with additional parameters for complex rendering scenarios.
Duration: 13m 37s
The macro in this lesson provides an efficient way to manage screen windows across multiple cameras. Automating aspect ratio calculations eliminates the need for manual adjustments. Tony demonstrates best practices for creating user-friendly tools with dynamic parameter visibility.
Duration: 9m 36s
This lesson showcases a streamlined workflow for managing motion blur in Arnold by consolidating settings into one control. Tony demonstrates a three-option setup that gives artists flexibility to render blur or generate vector passes without manual adjustments. This custom tool improves efficiency and reduces errors.
Duration: 5m 32s
This lesson covers a basic lighting setup in Katana, emphasizing scene organization and flexible asset management. Tony demonstrates techniques for matching CG elements to photographic plates through HDRI manipulation. By following these best practices, artists build efficient lighting setups that adapt to pipeline requirements.
Duration: 24m 2s
Creating light AOVs gives compositors flexibility to adjust lighting without re-rendering. Tony shows how building a reusable macro with user parameters allows artists to quickly generate AOVs for any light source. This workflow is critical for meeting production deadlines and creative requirements.
Duration: 11m 28s
An efficient material workflow for character lighting is established by leveraging parent-child relationships. Tony demonstrates how this approach allows for global changes while maintaining flexibility for variations like car paint or chrome finishes.
Duration: 12m 27s
This lesson demonstrates essential techniques for realistic CG integration, with a focus on handling shadows and reflections. Tony shows how camera projection for environment materials and rendering separate passes allows for photorealistic results. Reflections must account for scene shadows to ensure contact points look believable.
Duration: 9m 26s
Creating multiple AOVs is essential for flexible compositing workflows. Tony explains the difference between built-in AOVs and custom light path expressions, allowing artists to tailor render outputs. The ability to tweak expressions provides greater control over the final process.
Duration: 9m 51s
In this lesson, the instructor presents an efficient workflow solution for managing render passes by creating a customizable AOV macro with selective activation. Tony implements a checkbox-controlled switch system, allowing artists to activate only the needed AOVs. This approach provides flexibility and efficiency for various production shots.
Duration: 7m 32s
Setting up proper render output paths is essential for keeping files organized. Tony shows how a systematic approach using expressions creates a flexible structure that organizes renders by project and AOV type. Understanding this process allows artists to establish professional workflows for personal projects.
Duration: 13m 42s
The OptScript macro provides an automated solution for AOV naming conventions. Tony shows how a reusable macro updates render pass names based on the connected node. This approach streamlines the workflow and reduces potential naming errors.
Duration: 12m 35s
Katana provides essential knowledge for production rendering, emphasizing the distinction between preview and final disk renders. Tony explains that a command-line batch rendering workflow is crucial for rendering frame sequences efficiently.
Duration: 7m 14s
