I have tried to accomplish this for hours now. I am overlooking something.
Would be awesome if you guys could help me out:)
I have created a simple BP containing an arrow (root, visible ingame) and a spotlight, so you can easily recreate it if you want to.
The arrow should always point at the player.
I made it work once by breaking the rotation and doing some math on pitch yaw and roll, but as soon as i rotate the BP in the vieport everything was off again.
