The ground is the landscape. The city is the special actor which inherits from “actor” class and then for abstract “CityCollider” class (this class has only root component, whereas the specific class has several box, capsule and other colliders). I tried the line trace for Camera channel, from far above the main scene to far below it, and this detects the landscape but does not detect the city. The city boxes have collision profile “OverlapAll” with object type “WorldStatic” and option “Generate Overlap Events”. I also tried “Generate Overlap Events During Level Streaming”, but this did not fixed the situation. What I need to do? Maybe there is quite another solution?
I think you have to set it to block, at least the camera channel.
Unbelieveable, but this works! Great thanks for this very nice answer!
