PmxEditor - The reference editor for Pmx/Pmd models

PMX Editor is a 3D model engineering and editing software designed specifically for the MikuMikuDance (MMD) ecosystem. Unlike traditional modeling software, it is not used to sculpt a shape from scratch, but to configure, optimize, and modify the internal structure of existing 3D files in .pmd or .pmx format.

Easy installation with MmdStart

PmxEditor was created by Kyokuhoku-P (極北P) from Japan. Its creator maintains the software and publishes a new version from time to time.

PmxEditor was originally in Japanese only; it was translated through reverse engineering not approved by its creator.

Features

So many that a single site would not be enough.

In addition to editing models, it allows converting a pmx to ‘.x’ format, which allows creating accessories for MMD.
To complement PmxEditor, many plugins have been created; a large portion is shipped by default, also in a translated version.
Some aspects of Pmx files can be edited in Blender with the MMD plugin, but that’s a tiny fraction of what PmxEditor can do. However, for modifying the mesh and doing weight painting, Blender is more intuitive.
