I'm trying to draw a crosshair at the end of my trace.
If my crosshair does not hit a pawn or static mesh (ex, just a skybox) then the crosshair stays locked on a certain point at that actor - I want to say its origin.
Ex: Run across a pawn, then it turns yellow and stays on that pawn. If it runs across the skybox, then it stays at one point on the box. Weird?
How can I get my crosshair to stay consistent? I've included two images for reference, to help illustrate.
Note: The wrench is actually my crosshair. The "X" is just a debug crosshair. Ignore that.
