In depth

The defaults are written for an arm of several metres and they do not scale down. The speed ceilings are stated in metres a second, which is the unit that matters for a crane and the wrong one for an arm shorter than a hand: on a 170 mm boom neither ceiling ever binds, only the damping acts, and the trade the ceilings were chosen for is not the trade being made. Reported from outside on a 46 mm subject — a lip sweeping across a 170 mm arm left the eye 71 mm inside the wall on the first tick and inside it at all for 78 ticks of 120, 1.30 seconds — which on a subject that small renders the inside of the masonry: a black screen with the game running perfectly behind it.

Infinity is the immediate answer and needs no special case. damp is lerp(a, b, 1 - exp(-lambda dt)), so an infinite lambda returns the target exactly, and an infinite speed leaves the clamp unbounded. A rig that must come out of a wall on the tick it touches one passes retractLambda: Infinity, retractSpeed: Infinity and keeps the easing on the way back out, which is the half that stops the picture pumping.
