Copies English shape keys to their Japanese counterparts for MMD animations.

Copy to MMD Visemes

This blender add-on was created to easily create copies of viseme shapekeys with the japanese names that MMD animations would expect. It is primarily aimed at use for VRChat MMD Worlds to enable your avatar to lipsync and do facial expressions to the songs.

After installing the add-on the "MMD Shapekeys" interface will show up in the Object Data properties tab (where the shapekeys are listed as well)

• [x] Fill Existing Target Shape Keys As Placeholder: if the correct japanese shape key name already exists on the model, set that as the value. This key will not be duplicated, the primary purpose is to show that this Viseme / shapekey is already set up.
• [Import from / Export to Clipboard]: Saves / loads the values as JSON for easier sharing. If a configuration references a shape key that does not exist on the model it will be ignored.
• [Prefill Values] Fill in the existing shapekeys based on their names. Visemes can have a prefix, for the other shapekeys like blink the names must match. Values that have already been set will not be overwritten.
• [Duplicate Shape Keys With MMD Names] will clone the shapekeys set in the list and give them their Japanese MMD names. An empty shapekey will be added below the Visemes, and above the other shapekeys to have them grouped.
