After this video (1) and some testings I see it that way :
a)
Plastic elements works ok connected to non-plastic elements, in the above mentioned video see example of red blanket on 01:43 (rotation, and xyz changes, are transmited)
b)
Non-plastic elements, connected to plastic elements (nodes), works with limitations. (just xyz changes are transmited, not rotation). To avoid, somehow, this limitations you can use expressions as indicated here (2),
