The UE 5.1 retargeting page documents two IK Rigs with retarget chains, a retarget root (typically pelvis), a retarget pose for A/T-pose differences, fuzzy chain-name matching, batch retargeting via Duplicate and Retarget, and global/per-chain settings including stride warping and speed planting. It overlaps the live-docs reading in CA-B197 (C2-B21-D3-01), here pinned to the 5.1 edition.
