Improving and modifying the PCG graph

In this section, we’ll dive into the PCG graph and focus on adding and tweaking several nodes to improve the overall efficiency of the PCG tool.

For this exercise, we will add the Pack03-LandscapePro asset, and this time, it will be a grass asset that is procedurally spawned on top of the rocks:

1. To find this asset, go down to UE5_PCG_Chapter_04 | STF | Pack03-LandscapePro | Environment | Foliage | Grass and search for SM_PlantGroup01.
