Common Troubleshooting

Here are some common questions and problems that people have.

Ensure you have a NavMesh in your level; it is required for AI movement in Unreal. Also, make sure it is scaled to fit your terrain.
Ensure your custom character has the correct AI controller set in the class defaults. It will not move without this setting.
If your crowds are not spawning, check for collisions. If the spawner is colliding with something else, they will not spawn to prevent glitches
If using a custom character, please make sure they operate with both spawned and placed in world, unreal defaults to placed in world only.
The Spline blueprint is no longer editable out of the box in 5.4+, it will show up as purple. To fix this go into the BP_PedestrianPath and search for “Override construction scripts” on the spline component.
There is also a video tutorial going over how to set this up: https://youtu.be/ioLhK0VTVjo
