Material Maker vs MeshCoat

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.

MeshCoat is free 3D texture-painting software for game developers and 3D artists. It runs on Windows, macOS and Linux, operates locally, needs no account or subscription and loads textures from folders on disk. Brush strokes are mapped from 3D camera space into UV coordinates in real time with hardware-accelerated shaders. A non-destructive layer stack supports hiding, reordering, opacity changes, duplication, merging and live blending. Tools include brush, stamp, eraser, fill bucket, effects brush, eyedropper and face selection. Edge-wear and crevice-dirt generators provide real-time previews with colour presets. A screen-space stencil displays reference images for painting or decal projection, and a texture shelf browses local PNG and JPG files. MeshCoat imports OBJ, GLB and glTF models and exports composite maps as PNG. The maker says composite results update at 60 FPS, with 100-step undo and redo. The app is in development, contains no telemetry or network calls, and has no runtime AI or machine-learning models. It is licensed under GPL-3.0-or-later and accepts optional contributions.
