What Are MMD Original Characters?
MMD original characters are custom 3D models created by independent artists specifically for use in MikuMikuDance (MMD) software. Unlike models based on existing franchises, these characters are born from the creator's own imagination, complete with unique designs, backstories, and personalities. The best MMD original characters feature high-quality modeling, robust rigging for animation, and expressive facial morphs. They are the lifeblood of the MMD creative community, enabling animators, storytellers, and VTubers to produce unique content without relying on pre-existing intellectual property.
