What MechaPaint is
MechaPaint is a standalone 3D application for painting and texturing models on Windows and macOS. You can paint directly over model surfaces, including seams and submesh boundaries, while each submesh has its own layer stack. Layers support opacity changes, merging, hiding, recoloring, and image imports. Animated models can be scrubbed to a chosen frame for pose-specific painting. PhotoMesh turns a photo into a textured, paintable model as either a relief sheet or closed solid. Imports include FBX, OBJ, LWO, USD, glTF, GLB, DAE, STL, PLY, and 3MF; USD import is currently Windows-only. Exports include PNG textures and FBX or OBJ geometry, with presets for Roblox, Unity, Unreal, and Polytoria. The app paints base color, while roughness, metallic, and normal channels are in development. A free download has no time limit but watermarks exported textures. The perpetual license costs $39.50, paid once and includes one year of free upgrades.

Who it suits
MechaPaint suits 3D artists and developers who need layered texture painting, animation-pose painting, or photo-based models. It fits Windows and macOS users working with the listed modeling and game-engine workflows.
Verdict
MechaPaint combines direct 3D painting, per-submesh layers, animation posing, and PhotoMesh in a desktop app. The free version allows full-time use with watermarked exports, while the $39.50, paid once license removes that limitation and includes one year of upgrades.
