What Is an MMD Plugin?
An MMD plugin, or an essential companion tool, is software designed to extend the functionality of MikuMikuDance. The MMD ecosystem is largely driven by individual developers and a passionate community, so many 'plugins' are actually external programs or effect files. These tools handle a wide range of tasks, from adding stunning visual effects and editing 3D models to automating complex animation processes like lip-syncing and camera movement. They are indispensable for beginners and experts alike to fix common issues, improve visual quality, and streamline the creative workflow.
