AUSTIN, TEXAS - MechaPaint is available now for Windows and macOS: a 3D model painter you point at a model you already own, paint on directly, and export from without a conversion dance, a plugin, an account, or a subscription.
Texture painting has spent a decade getting heavier. Bigger installs, longer launches, more of the artist's day spent negotiating with a pipeline instead of painting. MechaPaint goes the other direction. Drag a mesh onto the window and it is already loading. Press a key and you are already painting on it.
It opens what other painters refuse to open
OBJ, FBX, glTF, USD, and native LightWave LWO3, read directly, with surfaces arriving as paintable submeshes, layers arriving as parts, and color textures located automatically from the model's own material graph. Six image formats were hand-decoded so an artist would never again be told a file is unsupported: TGA, BMP, HDR, TIFF, EXR and PSD, alongside PNG and JPEG. Decades-old archives that no modern painter will touch open in seconds and paint like new work.
The model tells you what is wrong with it
MechaPaint does not just show faults, it paints them onto the mesh. Bad geometry, missing UVs, overlapping UVs, flipped normals, open edges, unlit surfaces, unpainted surfaces, buried geometry, and a texel-density heat map, all rendered on the model in color, on their own layer, where a number in a panel could never point. When the UVs are past saving, Rebuild UVs generates a modern layout and carries the existing paint across onto it.
Real materials, real output
Full layer stacks with blend modes, opacity, masking, symmetry, patterns, clone stamp, decal stamps, reference windows with background keying, a bump brush that writes true height with a shaped cross-section, and a metallic roughness PBR pipeline. Export presets target Unity, Unreal, Godot, Roblox and Polytoria with the correct suffixes and the correct handedness, and the originals are never overwritten.
Priced like a tool, not a tollbooth
MechaPaint is a one-time purchase. It is currently half off during the launch sale. There is no seat server, no cloud round trip, and no month in which the software you paid for stops working.
We are just getting started
What ships today is the foundation, not the finish line. glTF and GLB export, a full painted-channel PBR workflow, and a deeper diagnostics suite are already built and moving through test. The roadmap runs well past this release, and it is being written in public, nightly, on the Updates page and in the Discord.
The painting app for 3D artists was supposed to get simpler, faster, and cheaper. Nobody did it. So we did.
Availability: MechaPaint is available now for Windows and macOS at mechapaint.com. A free version runs the full app with watermarked exports; buying unlocks watermark-free output.
