Update Spline Collision at Runtime W/ Blueprints

I’m working on a blueprint to create a procedural race track, that adds spline points at random points (within certain ranges for control) during play. But when I’m adding these points, the collisions on the spline mesh aren’t updated, so when I try and drive on the new stretch of track, my car just falls through. Anyone have any ideas?

I found this as a new feature in 4.11, but I still can’t quite get it to work for some reason :confused:

Bump - anyone know if this is possible?

Did you try turning collisions on in the blueprint on the spline mesh.

Yes, still didn’t update the spline collisions when the spline was updated at run-time.

Any Epic staff members know anything about this? It’d be super awesome if it does work, there’s so much potential!
