Bone References
These properties define what bones will be affected by this modifier.
Pelvis is the pelvis or hip bone.
Spine Bones is the bone chain that will be affected by the leaning rotation.
Spine bones example.
Animation
These properties define the leaning motion.
Rotation Curve is the animation for spine bones.
Translation Curve is the animation for pelvis.
Rotation and Position Smoothing control the interpolation speed for rotation/translation.
Playback Speed is the animation speed multiplier.
Leaning
These properties control the leaning rotation.
Max Lean Angle is the max rotation angle in degrees.
Lean Intensity controls how strong the leaning rotation will be.
Use-cases
This modifier can be used to add dynamic leaning rotation effects when moving around. The default settings are already adjusted to work with any character, except for spine bones:
