Guys i made new input keys Mouse wheel up and down… if u move mouse wheel up grabbed object will move further away from u so trace line end will increase because MaxReach Will increase… and if u move ur mouse wheel down MaxReach will decrease so trace line end will decrease and it will come closer to you… and if u release grab MaxReach will go to default… 
i made this but i want to make something like this: when u will grab object, it must not jump to center of object (for example see my video at 3 seconds)… so when u grab something, it must stay at the same position if u dont move mouse… so ur AActor grabs objects at any point not only center…
