Hi Przemek!
If I understand it correctly, clustering uses one entity for each cluster. It would by super useful if it was possible to specify 'cluster index' so that there could be instances of several entities picked for a cluster.
Realworld example, there are 9 entities, 3 of grassA, 3 of grassB and 3 of grassC. I would like to have patches of species, so that a cluster is made of all three models of grassA, another of grassB and so on, obviously with instances randomized within given selection.
Would something along these lines be possible? If it is a problem to add another data (clusted index) to entity, it could use the display colour for example, or parse the name in some way.
