Overview
Modify Bone Chain has the same function as Modify Bone, but it applies translation and rotation to a chain of bones.
-
Chain To Modify — bones that will be affected.
-
Position — translation offset; it’s possible to bind an external value here.
-
Rotation — rotation offset; it’s possible to bind an external value here.
-
Space — what space the offset will be applied in.
-
Mode — whether to add or replace bone transforms.
Use-cases
This modifier is useful when there’s a need to rotate multiple bones at once. For example, the FPS Add-on uses this feature to implement trigger discipline:
Tip: When a character is sprinting, this layer will apply 45 degree rotation around the Z axis for the right index finger bones.
