Once you have transformed some bones, if you want to return to their rest position, just clear their transformations.
Resets location, rotation, and scaling of selected bones to their default values.
- Location, Rotation, Scale Alt-G, Alt-R, Alt-S
Clears individual transforms.
Note that in Envelope visualization, Alt-S does not clear the scale, but rather scales the Distance influence area of the selected bones. (This is also available through themenu entry, which is only effective in Envelope visualization, even though it is always available...)
- Reset Unkeyed
Clears the transforms to their keyframe state.
- Only Selected
Operate on just the selected or all bones.
