I was following the aim offset tutorial below in UE4.15, the aim offset previews look perfect however when I finished setting up the blueprint logic in the tutorial I get violent snapping when I move my camera to the sides of my character. If I keep the interpolation 15 it gets worse…
Now I’ve gone through the tutorial multiple times looking for what I did wrong but I don’t see anything wrong. It feels like some functionality changes have caused this from the newest version of UE4.15 between when the tutorial was created.
I downloaded the project and found your error. In the Animation event graph where you construct the rotator from Aim Yaw and Aim Pitch, you accidentally set your Yaw as Roll.
The easiest to achieve that is to lower your interpolation speed. This would however cause your gun and character to trail after your crosshair. Which could give a more unique look to your game. It all boils down to your intended design. If not… I would go about having one interpolation speed for the common case, meaning just aiming, and one for when your Yaw transitions between the extremes (-90 to 90 etc). Best of luck (•ᴗ•)
