About ModBoo

ModBoo is a local-only 3D character studio that runs entirely in your browser. Open the PMX, PMD or glTF models you choose, play VMD motion and physics, and adjust expressions (morphs) and shading.

A mod (mod.json) can change textures, materials, mesh visibility, accessories and expressions in one go. You can also put game XXMI (3DMigoto) outfit mods on the same character's PMX.

Files are processed only inside the browser and are never sent to a server. There is no feature for extracting, decrypting or bypassing game files.
