The tests I have done so far have not reached that point, but one of my assets has 340 plastic chair in an array, with 1 “real” one and the rest instances.
Previously, navagating the scene took forever, (Old quad core running XP), tested this with Xref, there was a noticable speed increase, plus, the ability to ensable visibility with one click was an added bonus.
My imagination is reaching overload with ideas of Xref usage.
Thanks for all your help.
