Have actor bounce off of landscape

Hi everyone,

I’m currently working on a first person VR flight simulation.
After setting up satifying controls I now I ran into a problem with collision and collision detection.
I want it to have so that when the player flies into the environment or landscape he will bounce off of it with x y z axes mirrored. I have so far found the according nodes to do that, but for some reason the collision won’t work.

I have the landscape set to generates overlap event, since it doesn’t hat the option generates hit events.
I have set the meshes for the wings set to the same. Nothing. I tried putting collision boxes around the meshes with the same settings. Nothing.

It doesn’t trigger the event overlap. It doesn’t trigger the event hit.

Please help.
