◻️Copy Bone

Overview

Copy Bone copies data from one bone to another:

• Copy From is the bone to copy data from.

• Copy To is the bone to copy data to.

• Copy Mode defines how the pose will be copied:

  • (Default) Replace will replace the target transform.

  • Add will accumulate the target transform.

• Copy Position controls whether to copy position.

• Copy Rotation controls whether to copy rotation

• Copy Position controls whether to copy scale.

Use-cases

This modifier is mostly useful for IK bones. For example, here is a setup that's used in the CAS Demo:

1. Copy data from real bones to IK (e.g., from right hand to IK hand_r).

2. Animate the IK target (e.g., add translation to IK hand_r).

3. Apply IK (e.g., Two Bone IK for the right arm).
