Description
BuildSplineSkinWeights (v1) Experimental
Build spline skinning data from skeletal mesh
Input(s) : Collection - Managed array collection to be used to store datas VertexSelection - Vertex selection to focus the geometry transfer spatially SkeletalMesh - SkeletalMesh used to compute spline skinning weights. Will be stored onto the groom asset LODIndex - LOD used to build skinning weights RootBones - Root bones to be used for spline skinning. Uses all bones if empty. Note that branches in the skeleton is currently not supported. SamplesPerSegment - Number of spline samples per bone segment.
Output(s): Collection [Passthrough] - Managed array collection to be used to store datas SplineParamKey - Spline Skinning Parameter key SplineBonesKey - Spline Bones key containing root and end spline bone. To be used in other nodes if necessary
