Description
TransferVertexAttribute (v1)
Transfer float properties from a source collection to a target collection. Component Transfer is used when all geometries from the source collection have matched names with the target collection. Otherwise, Global Transfer is used. Geometries are matched when the geometry's BoneName can be found as the start of the BoneName of a geometry in the target collection. Use TransformNameSuffix to add extra string to the source geometry's BoneName to avoid multiple matched names. For example, source geometry has name SK_10 and target geometry has name SK_10_tet1 For all names, Check BoneName attribute in Transform group in the collection.
Input(s) : Collection - Target collection to transfer vertex attribute to. FromCollection - Source collection to transfer vertex attribute from. AttributeKey - The name of the vertex attribute to generate indices from.
Output(s): Collection [Passthrough] - Target collection to transfer vertex attribute to. AttributeKey [Passthrough] - The name of the vertex attribute to generate indices from.
