✨The definitive guide to creating powerful tools, custom UIs, and production-ready addons in Blender with Python.✨
This hands-on guide teaches you how to extend Blender using Python, from writing simple scripts to building full-featured production tools. You'll explore the structure of the bpy module, learn how to create custom UI components, and integrate your tools into Blender's workflow—perfect for technical artists, tool developers, and studios.
Whether you're designing panels, gizmos, or standalone add-ons, this book walks you through real-world examples, best practices, and debugging strategies. You'll even explore PySide integration for advanced UI, asynchronous behavior, and a professional case study from Blender Studio to inspire your own development process.
