Edit Armature

Edit mode with an armature active

Transformations

The list of available transformations depend on the active armature. The addon reads the active armature structure and tries to detect a known model (e.g. Mannequin or Mixamo).

Unknown armature

By default (for a single bone in this example), no transformations will be available (thus, empty menu).
