Animation Rig Biped Arm object

Provides parameters to animate the arm for a biped character.

Parameters

Display Bodypart

Toggles the display of proxy geometry for the spine.

Animation

Control LOD	Changes the level of display for the arm controls.
Set Animation Defaults	Sets the animation parameter values to their default values.
FK/IK Blend	Blends between forward and inverse kinematic solutions.
Match FK to IK	Matches the FK rotations to the IK solver end positions.
Match IK to FK	Matches the IK solver end positions to the FK rotations.
Stretch Ratio	Controls the stretch ratio for IK body parts. A value of 0 is no stretch, and a value of 1 is full stretch. Stretch is a percentage of the distance between the end of the bone and IK control.
Custom Control Space	Provides a custom control space to IK solutions. This allows you to lock the controls to an object in world space, independent of the rig space.
Custom Space Blend	Blend between the standard and any custom IK space.
Wrist World Space Blend	Blend between local and world space for rotations.

The rest of these parameters provide controls to translate and rotate parts of the arm.

FK Stretch Controls

Provides controls to FK stretch controls for translating the forearm, wrist, and arm curve.

Rigging

Hook Object	The path of the hook object. Note The hook object provides parent transforms to the body part.
Hook Controls	References to global character placer so the arm moves relative to it.
Side	Determines if the arm is the left or right arm of the character.

Pretransforms

Provides controls to change the pretransform positions of the parts of the arm.

Bone Rotations

Provides controls to rotate the collarbone, shoulderblade, upperarm, and forearm.

Bone Rest Angles

Provides controls to set the bone rest angles for the collarbone, shoulderblade, upperarm, and forearm.

Bone Lengths

Provides controls to set the bone lengths for the collarbone, shoulderblade, upperarm, and forearm.

Bone Kinematic

Provides controls to set the bone kinematics for the collarbone, shoulderblade, upperarm, and forearm.

Hook Out Rotations

Provides controls to set the hook out rotations for the collarbone, shoulder, elbow, wrist, and shoulderblade.

Preferences

Display Bones	Toggles the display of bones on the rig.
Display Animation Controls	Toggles the display of animation controls on the rig.
Display Proxy Geometry	Toggles the display of the proxy geometry for the body part.
Control Scale	Modify the per-part control scale.
Control Color	Modify the per-part control color.

Control Level of Detail

These parameters allow you to modify the display of the collarbone, FK upperarm, gimbal FK upperarm, FK forearm translate, FK forearm, FK wrist translate, wrist twist local space, wrist local space, gimbal wrist world space, IK wrist, IK shoulderblade, IK twist shoulderblade, IK twist, and arm curve.
