I have not been able to find the Fracture Editor tab, even though it’s enabled as a plugin. Right now, any time I select a Geometry Collection with the Mesh Editor tab open, I get a crash:

Yeah you have to put those field assignments in the UE4Editor.Target.cs and then compile from the 4.23 github source for it to show up. After you do that, I wouldn’t recommend doing any fracturing with the “Mesh Editor” tab and instead stick to the “Fracture Editor” tab.
