PCG Spline Collision

Could someone please help point to or help explain how to add collision to the PCG spline actors from the ElectricDream map?

I’m a bit confused around the SplineExample map for example. The PCG spline has no collision and I’m not sure where the check box is, if I need to convert it or need do something additional.

@sabottynoob Did you find a solution? I got the same problem… the mesh has complex as collision and block all, the mesh spawner has also block all enabled but not collision…
