The damping ratio (ζ) applied to the rotational part of the constraint. Only used if IsKinematic is false.

A value of 1 corresponds to critical damping, where the constraint reaches its target orientation as fast as possible without overshoot in the absence of other forces or constraints. Values less than 1 are under-damped and oscillate around the target before settling. Values greater than 1 are over-damped and approach the target more slowly without oscillation. A value of 0 applies no angular damping, causing the constraint to oscillate.

Even with this property set to 1, an AnimationConstraint at the root of a multi-body mechanism may still exhibit low-frequency oscillation because it does not "see" the full effective mass of the downstream chain. You can compensate by increasing both AngularStrength and AngularDamping beyond their defaults.

Controls how rigidly the constraint enforces the rotational part of its target Transform. Only used if IsKinematic is false. The resulting torque is capped by MaxTorque.

AngularStrength is defined as a normalized natural frequency, AngularStrength = f / 60, where f is the target natural frequency in Hz. The default value of 1 corresponds to a target frequency of 60 Hz and produces strong tracking of the target orientation. A value of 0 applies no torque. Values less than 1 produce a softer, more compliant rotational response, and values greater than 1 produce a stiffer response.

Use values significantly greater than 1 with caution, as they may cause the simulation to become unstable.

When true, the connected parts follow the Transform perfectly without participating in physics simulation. When false, the connected parts follow the trajectory using forces and torques limited by MaxForce and MaxTorque.

The damping ratio (ζ) applied to the translational part of the constraint. Only used if IsKinematic is false.

A value of 1 corresponds to critical damping, where the constraint reaches its target position as fast as possible without overshoot in the absence of other forces or constraints. Values less than 1 are under-damped and oscillate around the target before settling. Values greater than 1 are over-damped and approach the target more slowly without oscillation. A value of 0 applies no linear damping, causing the constraint to oscillate.

LinearDamping has no effect when LinearStrength is 0.

Controls how rigidly the constraint enforces the translational part of its target Transform. Only used if IsKinematic is false. The resulting force is capped by MaxForce.

LinearStrength uses the same normalized natural frequency definition as AngularStrength, LinearStrength = f / 60, where f is the target natural frequency in Hz. The default value of 1 corresponds to a target frequency of 60 Hz and produces strong tracking of the target position. A value of 0 applies no force. Values less than 1 produce a softer, more compliant positional response, and values greater than 1 produce a stiffer response.

Splitting angular and linear parameters lets you make orientation tracking stiff while keeping positional tracking soft, or vice-versa. As with AngularStrength, use values significantly greater than 1 with caution, as they may cause the simulation to become unstable.

Maximum force magnitude the constraint can apply to achieve its goal. Only used if IsKinematic is false.

Maximum torque the constraint can use to reach its goal. Only used if IsKinematic is false.

The internal CFrame that is manipulated when the constraint is being animated.

Note that AnimationConstraint transforms are not applied immediately, but rather as a batch in a parallel job after RunService.PreSimulation, immediately before physics steps. The deferred batch update is much more efficient than many immediate updates. If the AnimationConstraint is part of an animated model with an Animator, then Transform is usually overwritten every frame by the Animator after RunService.PreAnimation and before RunService.PreSimulation.
