This is a native transient structure.

API > API/Runtime > API/Runtime/Engine

This is a native transient structure. Contains:

  • BoneIndicesArray: Array of RequiredBoneIndices for Current Asset. In increasing order. Mapping to current Array of Transforms (Pose).
  • BoneSwitchArray: Size of current Skeleton. true if Bone is contained in RequiredBones array, false otherwise.
