Hello, this is the first post I've written since I started making a document.

What is MMD?​

MikuMikuDance (MMD) is a free 3D animation software developed by a Japanese programmer named Yu Higuchi. It was initially released in 2007 and gained popularity quickly within the anime and virtual idol communities. MMD allows users to create and animate 3D models, primarily focusing on humanoid characters, using a straightforward and intuitive interface.

MMD still has a large community, and all the high-quality 3D models and motion assets created from them are stored in MMD's custom formats, PMX(Polygon Model eXtended) and VMD(Vocaloid Motion Data). These assets are often shared on the Internet, and many people use them to create videos and images.
