Setting up the PCG crowd graph

We just reached the final part of this chapter, and we will create a PCG graph that is capable of spawning actor characters across the level. I will show you how to set up a logic system for spawning the actors from the PCG graph:

1. Inside your PCG folder, right-click and create a new PCG graph, and let’s call it PCG_Crowd.
