The camera controls for mouse is fine, but when a gamepad is used, camera moves far too fast and i tried setting up various triggers and modifiers. I couldn’t figure out how to use these to weaken the gamepad stick input strength.
Deadzone is to fix wandering analog inputs. Not what you want to fix this.
To scale the input (per axis, but you can just set them the same), try the Scalar modifier.
I tried that last night, scaler was not making any differences to the strength of the stick. A member of my team booted it up on their PC and the scalar was working on their side. I even gave them the same controller, too. So it looks like an issue on my PC side or my Unreal client.
