Bone Motors

Motor Usage
FK Motor Traditional key frame animation with rotation and translation for each bone
IK Motor Movement for consecutive series of bones, legs, tail, neck, etc; pose the end bone without needing to pose each bone
Smooth IK Motor Recommended for automated walk cycles; same as IK motor, but more subtle, guaranteeing no popping, but not as accurate as an IK Motor for positioning
IK Rotate Motor Designed for automated rotating walk cycles; the same as the IK Motor, but movement in a circular arc
Smooth IK Rotate Motor Designed for automated rotating walk cycles; the same as Smooth IK Motor, but movement in a circular arc
Bend Physics Motor Any type of bending or bouncing that is attached to another motor driving the force; floppy secondary motion, cloth, flesh
Smooth Bend Physics Motor Recommended for low end devices that cannot expend the compute power; the same as Bend Physics Motor, but less accurate and lower quality
Pin Rope Physics Motor Pin the end/ends of consecutive bones; the physics reacts to the ends that aren't pinned. For example, a vine, rope, or hair held on one end -- direct with motion on the areas that are not pinned.
Rotate Cycle Motor A rotation motor that rotates bones back and forth -- useful for rotation or to drive a Bend Physics or Pin Rope Physics Motor.
Move Bounce Motor Vertical and horizontal bouncing that can be combined, adds secondary motion to the other motors

Deform Motors

Motor Usage
Blink Motor Use for blinking
Cage Motor Deform/distort/morph/warp the mesh with an enclosing cage; pull on the external shell; distort the outline of the mesh region
Control Points Motor High quality blinking, talking, mouth opening/closing, area distortion and more; place a circular control point region of influence within the mesh, warp that region by translating/scaling/rotation and its surrounding points; directly manipulate areas on the mesh
Flap Motor Wing/object flapping
Physics Motor Soft body physics; squishy character, high quality cloth, hair, flesh, slimy/gooey material
