I`ve found that when an Actor is HiddenInGame, it still blocks the camera itself. Is there a way to completely erase its physical influence on the camera without destroying it while maintaining its ability to be clicked by mouse? Like the way I click objects with my mouse but never hit them with my viewport in the UE4 editor?
And also, I`ve just tried enabling only query and enabling only physics collision, but cannot achieve the desired effect with either one of them.
