Hi,
After separating part of the model I noticed that in attribute editor there are tens of unused nodes.
Even after this object is not grouped not in any layer etc.

I tried deleting by history and as many other types, but these nodes will not disappear.
I also tried duplicating and duplicating special.
I know that if I would export to fbx and import again, this probably would disappear, but that is long work around for 10s of millions of polygons.
It will make the scene extremely lagy.



How could I solve this? Does Maya has option to remove unused assets like that?
