Material Maker vs Mixos Paint

Material Maker is an open-source tool for authoring procedural PBR materials with node graphs and exporting them for game engines and movie assets. It supports static and dynamic PBR, raymarching, and dynamic unlit materials. The official site lists more than 200 nodes; users can create nodes by combining existing ones or describing them in GLSL. Materials can be exported for Godot, Unity, and Unreal Engine. Unreal requires extra steps: Unreal Engine 4 needs manual material setup, while Unreal Engine 5 uses a generated Python script that must be run in Unreal. The tool provides 2D and 3D previews, image and spritesheet export, and loading of custom OBJ models. An experimental procedural-brush feature can texture 3D models. A website library offers community materials, nodes, brushes, and environments. Material Maker runs on Linux, macOS, and Windows. It is free through Itch.io, with a Steam plan at $14.99 as a one-time purchase. Its code uses the MIT License and assets use Creative Commons Zero 1.0 Universal.

Mixos Paint is a browser-based tool for painting layered PBR materials onto 3D models, with brushes, geometry-driven smart masks, and live viewport updates. Layers support blend modes, opacity, and separate controls for color, height, roughness, and metallic channels. Smart masks can generate effects such as edge wear, curvature, grime, and cavity. The app imports GLB, glTF, FBX, and OBJ models, and lists 2,669 ready-made PBR materials; users can import their own material libraries. Painting is free without a time limit, but exporting finished texture maps requires a paid plan or license. Paid exports include PBR maps up to 4K and presets for Blender, Unreal, Unity, Godot, Cinema 4D, Maya, and Houdini. The free desktop app's Live Link streams changing maps to Blender, Cinema 4D, and Unreal. Pro costs $8.99/mo, Max costs $17.99/mo, and a Pro license costs $99 once. Mixos says editing runs on the user's device, but it has no certifications or uptime guarantee.
