Convert PMX to VMD

Understanding PMX and VMD file formats

PMX files are 3D model files used by MikuMikuDance (MMD), a popular animation software for creating dance animations with 3D characters. PMX files store detailed information about the model's mesh, bones, morphs, and materials.

VMD files, or Vocaloid Motion Data files, are used to store motion data for MMD models. These files contain animation sequences, such as character movements and facial expressions, which can be applied to compatible 3D models in MMD.

Can you convert PMX to VMD?

Direct conversion from PMX (model) to VMD (motion data) is not possible because they serve fundamentally different purposes: PMX files define the structure of a 3D model, while VMD files define motion or animation data. However, you can create VMD motion data for a PMX model using animation tools.

How to create VMD motion data for a PMX model

To generate a VMD file for a PMX model, you need to animate the model in MikuMikuDance or compatible software, then export the motion as a VMD file. Here’s how you can do it:

1. Open MikuMikuDance (MMD) and load your PMX model using File → Load.
2. Create or import the desired animation by manipulating the model’s bones and facial morphs.
3. Once your animation is complete, go to File → Export Motion Data or ファイル → モーションデータ保存 to save the motion as a VMD file.

Best software for PMX to VMD workflow

• MikuMikuDance (MMD): The primary tool for working with PMX models and exporting VMD motion data.
• PMX Editor: Useful for editing PMX models before animating them in MMD.
• Blender (with MMD tools add-on): Allows advanced animation and model editing, with options to export VMD files via plugins.

Summary

While you cannot directly convert a PMX file to a VMD file, you can animate a PMX model in MMD or Blender and export the resulting motion as a VMD file. MikuMikuDance remains the best software for this workflow.
