Introduction to Python Scripting in NUKE

Python, a popular scripting language, is integrated into NUKE. It allows us to control the user interface, modify many nodes quickly, and integrate with other applications. We can extend NUKE by learning Python commands and workflows, and create scripts that allow us to focus on creating art. This tutorial will begin by reciting the Python commands NUKE uses internally. Then we'll start writing our own code. We will then learn how to create nodes correctly, set properties at node construction and have our scripts run automatically whenever NUKE starts. We can then start working on projects such as a script that automatically selects nodes from a particular class based upon user input, or a script to automatically split a multichannel EXR into separate auto-cropped-shuffle nodes, so we can get started with compositing quicker. Software required: Nuke 6.3v6.
