Retarget poses, chains, and operation stack

Pose alignment

1. Create a named target retarget pose; do not overwrite the baseline without a reason.
2. Compare source and target in reference-pose view.
3. Align large axes first: pelvis facing, spine, clavicles, upper/lower arms, hands, thighs, calves, feet, and toes.
4. Use Auto Align as a starting point. Direction, local/global rotation axes, and mesh methods solve different mismatches; inspect every limb afterward.
5. Snap the character to ground when vertical reference offsets differ.
6. Scrub Retarget Pose Blend between 0 and 1 to distinguish reference-pose error from the stored correction.

Operation stack discipline

Operations evaluate top to bottom. Disable all nonessential corrections, establish a clean FK transfer, then enable one operation at a time.

• Retarget Pose: first in the stack; selects stored source/target pose overrides.
• Pelvis Motion: transfers and constrains pelvis movement; tune floor/crotch offsets only after the retarget roots and poses are correct.
• FK Chains: maps rotations/translations by chain.
• Root Motion: copies source root or generates it from target pelvis.
• Run IK Rig: applies goal-based target solving.
• Pin Bones / goal offsets / floor constraints: late corrections for explicit contacts.
• Remap Curves: needed when semantic curves have different names.

FK modes

• Interpolated rotation: default choice when chain lengths, proportions, or bone counts differ.
• One to One: corresponding bones transfer directly; use when counts and intent match.
• One to One Reversed: maps from chain ends; useful only when the end is the stable anchor.
• None: exclude the chain from FK rotation transfer.
• Translation None: preferred for most chains.
• Globally Scaled / Absolute / Stretch modes: use only for a specific diagnosed translation requirement; verify deformation and root behavior across clips.
