Customer-facing source, target, mapping, transform-copy, weight, and optional driven-limb grip fields for one IK mapping.
This structure is stored as editor authoring data. Synchronization validates it and compiles the supported result into the runtime snapshot; packaged runtime does not interpret the authoring structure directly.
struct FPoseOverlayIKMappingAuthoringProperties
Source Deform Bone
Source bone whose authored result supplies the mapping. Relative Follow may use a target finalized by an earlier mapping.
Target IK Bone
IK target bone modified by the mapping; duplicate target ownership and mapping cycles are invalid.
Mapping Mode
Chooses baked authored delta, exact final source following, or final source following with the incoming relative target transform preserved.
Weight
Strength of the mapping; zero produces no visible mapping contribution.
Solve Driven Limb
Makes the final IK Targets node solve one two-bone deform chain to this finalized target. Apply Authored Delta keeps the synchronized overlay target authoritative; Follow modes derive it from the incoming pose.
Driven Deform Bone
End bone of the driven two-bone chain, such as hand_l; its parent and grandparent complete the chain.
Take Target Rotation
Matches the driven end-bone rotation to the finalized mapped target rotation.
Allow Stretching
Allows the two-bone grip chain to extend beyond its original reach within the configured limit.
Start Stretch Ratio
Fraction of original limb length at which enabled stretching begins.
Notes
- Use the named editor controls. Stable IDs and derived payload fields that are not customer-facing remain omitted from the property list.
