Material Maker is a procedural materials authoring and (experimental) 3D model painting tool, based on the Godot Engine. Materials and brushes are defined as graphs where nodes create or transform textures, and can be exported for the Godot, Unity and Unreal game engines.
Most nodes are defined as GLSL shaders, and when connecting them, Material Maker will generate combined shaders (instead of rendering an image for each node). It is also possible to create new nodes either by combining and grouping existing nodes, or by writing your own GLSL shaders.
Material Maker is available for Windows, Linux and MacOS.
