Here are the graphs, mostly the same as shown in a few tutorials. The MassEntityAsset had to be set up differently on 5.3 to make it work. I don’t show the ABP or how it’s referenced but thats the normal setting in the character BP. The contents of the ABP were just a Walk anim to Output Pose. Pawn’s AI controller was default.
Setup:

I used three ZoneGraphs all configured like a couple of the tutorials I watched. Laid them out like below (please ignore the prototype appearance, I’m a lousy modeler and just create prototypes which will be replaced)
