Its finally happened!
Unity has a wonderful box-shaped gift for us all, a total overhaul of how Prefabs work!! I don't know about you, but literally the first thing I learned about in Unity was how to make a prefab... then I immediately tried to nest them and was terribly confused as to why it didn't work! Nesting prefabs is the most natural developer interaction in the world, and starting in Unity 2018.3 its actually going to work right (and also do a whole bunch of other new neat tricks). Even better? there's a preview build based on 2018.2 out RIGHT NOW!! Go grab it and get started!!
This wonderful, amazing new Unity feature inspired me to make the first ever official LotteMakes(Physical)Stuff mech <3
