What MechaPaint is
MechaPaint is a standalone 3D art application for painting and texturing models on Windows and macOS. It lets users paint directly on model surfaces, including across seams and submesh boundaries, and organizes work in a separate layer stack for each submesh. Layers can be adjusted for opacity, merged, hidden, recolored, or used to bring in images. For animated models, users can scrub to a frame and paint in that pose. PhotoMesh turns a photo into a textured, paintable 3D model as either a relief sheet or closed solid. The app imports FBX, OBJ, LWO, USD, glTF, GLB, DAE, STL, PLY, and 3MF files; USD import is currently Windows-only, with macOS support marked as next. It exports PNG textures and FBX or OBJ geometry, with orientation presets for Roblox, Unity, Unreal, and Polytoria. Painting is layered, and source files are not modified. MechaPaint currently paints base color; roughness, metallic, and normal channels are in development. The complete app and all tools are free without a time limit, but free exports carry a watermark. The perpetual paid license is $39.50, paid once and includes one year of free upgrades.
