"Overshoot" Viewmodel mechanism in HELLMET

[DevOrderless]

I want to recreate the “overshoot” effect in the game HELLMET. It’s clear that it uses a bounding box (as shown in the video), but it makes it look a lot more smoother than simply ONLY having a bounding box. How can I re-create this effect? I’ve tried using springs, but I don’t think that’s the solution. (Correct me if I’m wrong).

Also, I’m not sure how to add this effect on top of an already moving viewmodel. The magnitude of the overshoot seems proportional to the speed of how fast the mouse is moving. Here is what I use to move the viewmodel:

gunYawOffset = math.clamp(gunYawOffset, MIN_YAW, MAX_YAW)
gunPitchOffset = math.clamp(gunPitchOffset, MIN_PITCH, MAX_PITCH)

local freeAimRotation = CFrame.Angles(gunPitchOffset, gunYawOffset, 0)

viewmodel:PivotTo(head.CFrame * freeAimRotation * VIEWMODEL_OFFSET)

Limiting the viewmodel's rotational sway to a circular limit?

I would like to know how to limit a viewmodel’s weapon sway to a circle similar to Deadline and Insurgency, where if the viewmodel attempts to exit this limit, it will essentially just lock itself at that point in the circle’s circumference even when moving the camera. I have attempted to try to figure out how to do this, from searching about this topic about limiting the end position of 3D objects to the circumference of a circle while rotating around an origin point. There is nothing about th…
