All MagicaCloth data is recorded as a ScriptableObject, which is a shared container in Unity.
This will be saved as a sub-asset when prefabbed, as shown in the image.
These subassets are automatically deleted when they are no longer used.
However, due to some errors or problems, unnecessary subassets may remain in the prefab.
In such cases, it is possible to remove the unwanted subassets by performing cleanup.
How to use
Select the appropriate prefab to open the right-click menu.
Then select “Magica Cloth / Clean up sub-assets” to remove unwanted sub-assets.
