Apply existing animation clips from one rigged character to a different rigged character — same library, multiple models, no regeneration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Retarget Motion — One Library, Many Characters ## There is no retarget MCP tool. Read this before promising one. Summer ships **no** `summer_retarget_motion` tool, and no other MCP tool that re-projects an existing animation asset onto a second rig. Verify it yourself: `summer tool --list` prints every registered tool and there is no retarget entry. Never call one: the MCP server rejects unknown tool names outright. Two real paths exist. Pick by whether the target rig is Meshy-rigged. | Situation | Path | |---|---| | Target is Meshy-rigged and the clip name is on the curated list | Re-run `summer_generate_motion` against the target's `rigAssetId`. Same clip, ~30s, uses credits. | | Target is not Meshy-rigged, or the clip is hand-authored / Mixamo / bought | In-engine retargeting: `BoneMap` + `SkeletonProfileHumanoid` + `RetargetModifier3D`. No credits, no network, but you configure the bone mapping. | The rest of this skill covers both. ## When to use this skill - "I bought (or generated) one animation library — apply all clips to my five enemies." - "Goblin and orc have the same combat moves — share the library." - "I have 30 NPCs with the same idle / walk / talk loop." …

How to install
mdr add summerengine/summer/retarget@sha256:51daf3c9f6df6f3cThe line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
