Is it possible to clone objects by distributing objects on the PolygonCache of an XRef object?
If you drag an XRef to the Object field (in Object Mode) of a Cloner it is not possible to distribute objects (e.g. on edges).
If you select a sub-object of an XRef (seems to have a PolygonCache) the "Distribution" field appears and it is possible to clone objects along the edges.
Is there a workaround/solution?
