Expanding on the foundations of tool development, Unity 6 Editor Tools Essentials Vol. 2 takes your skills to a professional level by mastering advanced Editor APIs and modern workflows. You’ll begin by building complex C# controls and bindable elements within the UI Toolkit, moving beyond static layouts into dynamic, data-driven interfaces like TreeViews. As you advance, you’ll learn to bridge the gap between code and the viewport by creating custom Gizmos and interactive Handles for the Scene View. This volume also dives deep into the Asset Pipeline, teaching you to automate workflows with AssetPostprocessors and custom file importers. Then you'll finish up by architecting your own node-based tools using the new Graph Toolkit, and then taking the final steps of packaging and publishing your work to the Unity Asset Store. Combined with Vol. 1, this book provides the advanced technical knowledge needed to create robust editor extensions — whether for internal production tooling, or commercial distribution.
