In Edit Mode, you can control the bone roll (i.e. the rotation around the Y axis of the bone).
However, after editing the armature, or when using Euler Rotation, you may want to set the bone roll.
- Axis Orientation
- Local Tangent
Align roll relative to the axis defined by the bone and its parent.
- Global Axis
Align roll to global X, Y, Z axis.
X, Y, Z
- Active Bone
Follow the rotation of the active bone.
- View Axis
Set the roll to align with the viewport.
Set the roll towards the 3D cursor.
- Flip Axis
Reverse the axis direction.
- Shortest Rotation
Avoids rolling the bone over 90 degrees from its current value.
This is a transform mode where you can edit the roll of all selected bones.
