Build custom node-based editors for Unity.
Builds custom Unity graph and state machine editors, with scripted importers that turn authored graphs into runtime assets.
When to use it
Use for custom graph, node, or state machine editors, or migrating a GraphView tool; not for Shader Graph, VFX Graph, or Animator Controllers.
Give it a Unity project and the editor tool you want built; it creates the implementation and reports changed files, asset creation steps, and remaining work.
What you provide
Targets Unity Editor 6.6 or newer for graph tools; state machine tools require 6.7 or newer. Graph Toolkit is built into the Editor rather than installed as a package.
