How to Add to a Custom Level With V3

This page covers how to use the features of Procedural NPC Crowds in Blueprints.

How to add to your custom level:

To add crowds to your level, follow these steps:

1. Find the PedestrianSystem folder in the demo content for the plugin.

2. Once in the PedestrianSystem folder, go to the Path folder and drag the BP_PedestrianPath_V3 into your level.

3. Set the variables you need on the spline in the level. The important ones are the spawner actor, pathpoint actor, and distance between spawners and pathpoints. There should be default values for each if using the demo content but you may need to adjust for your level.

1. Use ALT+drag to add spline points. if they are purple and cannot move, see Common Troubleshooting.

2. Drag as many spline points as you need around your level, You can use multiple splines.

3. Add a navmesh to your level and expand its size to fit. you can click "P" on your keyboard to visualize it.

4. That's it, you should now have mannequin crowds walking around your level.

Note: This does not work in simulate when the player character is not valid.

How to snap the V3 Spline to other splines:

1. Add a copy Z offset to your spline, usually it would be a small value like 10.0

2. Pick an actor in your level with a spline using the Selected Actor with Spline variable in the details panel.

3. Click "Copy Selected Spline", you may need to scroll down to see it.

1. That's it, your pedestrian path should now follow that other spline in your level.
