To remove a muscle, bone or capsule from a Muscle deformer

1. Select the muscles, bones, or capsules you want to disconnect and select one or more Muscle deformed objects. The number and order of the selection does not matter.
2. Select Muscle > Muscle Objects > Disconnect selected Muscle Objects from the main menu bar.

   Weights are zeroed and the nodes are properly disconnected.

   If you have accidentally deleted or improperly removed/disconnected a Muscle Object, you can use Muscle > Skin Setup > Auto-Fix Deleted/Missing Muscles to correct this.
