What MeshCoat is

MeshCoat is a free 3D texture-painting tool for game developers and 3D artists, available for Windows, macOS, and Linux. It runs locally, needs no account or subscription, and loads textures from folders on disk. As you paint on a model, it maps strokes from camera space into UV coordinates in real time using hardware-accelerated shaders. Its 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 and color presets. A screen-space stencil displays reference images for painting or decal projection, while the texture shelf browses local PNG and JPG files. MeshCoat imports OBJ, GLB, and glTF models and exports composite maps as PNG. The maker says results update at 60 FPS and undo and redo extend to 100 steps. The app is in development and licensed under GPL-3.0-or-later.
