Material Maker is an open-source tool built on the Godot engine for procedurally authoring textures and painting 3D models, with textures and brushes described as interconnected nodes via GraphEdit. It offers Windows and macOS installs through Scoop, Chocolatey and Homebrew, community translations, and is MIT licensed.
What this means for indie developers：Indie game developers can use it as a free way to generate procedural materials and textures, and as a practical reference for node-based tooling built on Godot.
