Cant move up.

Hello, dear community. I cant make to move up my character using a simple code:

      FVector zvector = GetActorUpVector();
      AddMovementInput(zvector, 1.0);

Who can tell me why its not working, while GetActorForwardVector and GetActorRightVector are working perfectly?
Great thx!

The character’s gravity force may be higher than the movement force?

Dont think it’s a cause. I established MovementMode to Flying value. But need to check all variants. Thx)
