True First Person Shooter Camera with 2D Aim Offset: Body Rotation & Weapon Position Issues

It looks like you’re calculating sight in hand_r space, instead of hand_r in sight space. And you’re not using the resulting rotation from the calculation, in the next picture, where you interpolate… Also, regarding the interpolation, I assume the alpha value that’s being feed will reach 1 by the time you want to have the sight aligned, because even if your location/rotation were right, nothing would align until alpha is 1.

I can’t tell if you’re retrieving the current position of the hand bone every frame to use it to feed the event graph (or C++ code) calculations. If you are, and you use those calculations to feed the anim graph that will move the hand bone, it would cause the bone to lag behind the spot where you want it, because the event graph gets the bone position in one frame and the anim graph sets its position for the next, so I would avoid it…

Those are the first things that come to my head when I look at the link you showed us.

I see the distinction between the sight vs hand_r space now, I’ll correct that. What nodes would be best to do such a calculation? The alpha value for the interpolation is fed through a simple timeline in the character blueprint when the button is pressed. I haven’t had much of an issue with the bone lagging behind but if it becomes a problem I can easily move it to the anim graph.
