retarget

The retarget namespace — 5 functions.

globals/retarget/animation

globals/retarget/animation(clipRef: any, targetMeshRef: any, sourceMeshRef: any?) -> (boolean, string)

Retarget an animation clip onto a target rig, returning the VFS path of a new .anim whose channels name the target skeleton's bones with bind-pose corrected rotations. The source rig is the clip's embedded rig.zmsh (else sourceMeshRef's skin, else the skinned mesh beside the clip in its bundle); the target rig is targetMeshRef's skin. Play the result with animGraph.addClip(entity, path). Pure asset transform — no entity/ECS state.

globals/retarget/extractRig

globals/retarget/extractRig(meshBytes: string) -> string?

Strip a .mesh (ZMSH) payload to a lean skin-only rig: the skeleton with geometry removed, re-encoded as a ZMSH whose only content is the skin. Returns the rig bytes, or nil when the mesh carries no skin. A .animation composite embeds this as rig.zmsh so a clip travels with its own source rig.

globals/retarget/humanoidProfile

globals/retarget/humanoidProfile(meshBytes: string) -> HumanoidHolder?

Derive the humanoid retarget holder for a rig from a .mesh (ZMSH) payload, when that skeleton has the essential humanoid structure (a hips root, a head or neck, at least one full arm chain and one full leg chain). Returns nil for a rig that is not a humanoid — a prop, a plant whose leaves animate, a quadruped — so a clip from it stays a plain clip rather than joining the shared humanoid-animation pool.

globals/retarget/isHumanoid

globals/retarget/isHumanoid(meshBytes: string) -> boolean

Whether a rig is a humanoid avatar — true when humanoidProfile resolves a holder for it. Use this to tell a humanoid character apart from a generic animated mesh (a prop, a plant, a quadruped) before treating its clips as shareable humanoid animations.

globals/retarget/serializeProfile

globals/retarget/serializeProfile(holder: HumanoidHolder) -> string

Serialize a humanoid holder to the humanoid.profile file body: an editable YAML role -> bone-name map. Roles list hips-first head-to-toe through the limbs, then any extras name-sorted, so the file reads top-down and diffs stably. Edit a value to correct an auto-derived mapping.
