Now that Spine supports skewed scale, bone coordinate systems can be skewed. worldRotation
has changed to worldRotationX
. There is also a worldRotationY
, which is not necessarily perpendicular to the bone's world X axis.
appliedRotation
is the local rotation used to actually pose the bones. This can differ from rotation
(which is the local rotation) if a constraint (like IK) is applied.
worldSignX/Y
are 1 or -1, where -1 indicates the bone has been scaled negatively.
