boneIndices
The geometry source defining the mapping from bone indices in skeleton data to the skinner’s bones array.
Declaration
var boneIndices: SCNGeometrySource { get }Discussion
This geometry source’s semantic property must be boneIndices. Its data is an array of integer vectors, each of which corresponds to a weight vector in the boneWeights geometry source. Each component in a vector specifies the index of the node in the bones array for the corresponding bone weight component.
