Material Maker is a free and open-source alternative to Substance Designer. Of course, a lot of features are missing (and there’s no Undo), but Material Maker is still a wonderful software made by just ONE person! And still, it’s quite powerful. I followed the official intro and made a procedural brick material.
What I liked the most about Material Maker:
- Export materials to Blender and Godot
- Light and fast. Even with a beefy computer, Substance Designer runs very slow for me.
- Open-source! And made with Godot!
