Transfer source animation onto a reviewed character rig

Why use this

1. A source motion can use bone names and proportions that only partly resemble the target character. A mapping that looks complete in a table may still twist limbs, move the root incorrectly or overwrite animation the artist intended to keep.

2. A retargeting review packet could make ambiguous correspondences and preservation requirements explicit before applying constraints or baking keys. The artist could approve the mapping as a separate decision and define the motion checks needed before accepting a reusable track.

Why an agent / simpler alternative

Useful judgment

Compare rig hierarchies and identify ambiguous correspondences rather than treating similar names as sufficient evidence.

Simpler alternative

Use a known, artist-approved retarget preset when source and target rigs follow established compatible conventions.

Unsuitable when

Asset rights are unclear, the target rig is ambiguous or the only scene copy contains irreplaceable animation.

Proposed inputs

1. Name

   Rig descriptors

   Owner

   Animator

   Minimum scope

   Source and target bone names, hierarchy and rest-pose descriptions

   Quality check

   Identify root, deforming bones and unresolved anatomy.

2. Name

   Transfer brief

   Owner

   Animator

   Minimum scope

   Licensed asset references, target action and preservation requirements

   Quality check

   Specify existing tracks and scene elements that must remain unchanged.

Access and setup — proposed or unknown

Proposed minimum

1. Text-only fictional rig descriptions and a mapping proposal; no animation application access.

Compatibility unknowns

1. Unknown: current runtime, Blender version, add-on behavior, FBX interpretation and constraint compatibility.

External actions requiring approval

1. Asset access or installation, exact mapping, motion preview, baking and replacing animation; do not enable skip-confirmation by default.

Expected deliverable and review checks

Proposed artifact

Bone-correspondence proposal with confidence notes, unresolved mappings and motion-review criteria.

Critical checks

1. Anatomically ambiguous mappings remain unresolved for artist review.

2. A scene-copy and existing-track preservation plan precedes any proposed bake.

Missing output evidence

No new workflow run or output inspection is performed for this editorial layer. The linked implementation evidence retains the original source-specific outcome and artifact limits.

Failure signals and proposed responses

1. Signal

   A similarly named bone occupies a different hierarchy role.

   Why it matters

   A plausible name match can produce incorrect deformation.

   Proposed response

   Reject the automatic correspondence and request artist-confirmed anatomy.

2. Signal

   The proposed bake targets an existing action.

   Why it matters

   The transfer could overwrite work the artist needs.

   Proposed response

   Stop and specify a separate action or track with a preserved scene copy.

Effort and cost — unknown

Setup work

1. Inventory rigs, asset permissions and preserved animation.

Ongoing review

1. Inspect mapping ambiguity and later motion previews.

Unknowns

1. Unknown: manual correction effort, add-on compatibility and eventual render or processing costs.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

Two fictional rig hierarchies share misleading bone names, and the target contains an existing action with the proposed output name.

Acceptance checks

1. Flag the anatomical ambiguity.

2. Require a distinct output action and preserved source scene.

Stop conditions

1. Real assets, Blender execution, downloads or animation writes are required.

Limits

1. The proposed checks and safeguards are editorial recommendations, not evidence of successful execution or permission to act. The linked implementation retains its own observed outcome and approval limits.
