Every USD spelling
.usd, ASCII .usda, binary crate .usdc, and .usdz archives all open. A .usdz is unpacked and its root layer read in place.
USD + MechaPaint
Universal Scene Description, read natively. .usd, .usda, .usdc, and .usdz packages open as paintable models.
WHY MECHAPAINT
USD without a conversion step
I built a native USD reader into MechaPaint, so the format Pixar, Apple, NVIDIA Omniverse, and Houdini standardized on opens as directly as an OBJ. Every variant is covered, including the zipped .usdz packages iPhones and AR tools produce.
Meshes as parts
Each UsdGeomMesh becomes its own paintable part with its UVs, so a scene with many objects gives you many paint regions.
Native, so it is quick
The reader is compiled into the app. A USD file opens in the time it takes to read it from disk.
Out to the whole pipeline
Paint and export FBX, GLB, OBJ, or STL with PBR texture sets named for Unity, Unreal, Godot, Blender, or Roblox.
