Convert PMX to GLTF for free

PMX is a model file format used in Japanese MMD (MikuMikuDance) software, the full name is Polygon Model eXtended. The PMX format has better extensibility and functionality than the original PMF (Polygon Movie Format) and PMD (Polygon Model Data) formats of MMD. The PMX format file contains all the information of the 3D model, including the model's mesh, materials, bones, weights, animation data, etc. In MMD, users can create their own 3D characters and make various animations by importing model files in PMX format. The PMX format supports more types of materials, including specular reflection, transparency, glow and other effects, as well as a variety of bone types and animation interpolation methods, which can more flexibly express various movements and postures.

glTF (GL Transmission Format) is a 3D file format that stores 3D model information in JSON format. The use of JSON minimizes the size of 3D assets and the runtime processing required to decompress and use these assets. It is used by applications for efficient transmission and loading of 3D scenes and models. glTF was developed by the Khronos Group 3D Format Working Group and is also described by its creators as the JPEG of 3D.

The glTF file format defines a scalable, universal publishing format for 3D content tools and services, simplifying the creative workflow and enabling interoperable use of content across industries. The purpose of creating the glTF file format is to define a scalable, universal publishing format for 3D content tools and services, simplifying the creative workflow and enabling interoperable use of content across industries. It minimizes the runtime processing required by applications using WebGL and other APIs.
