Retargeting Motion-Capture Data

Character Animation > CAT (Character Animation Toolkit) > Working With Motion-Capture Data >

CAT uses retargeting to calculate pelvis positioning and defaults to FK rotations for the rest of the body.

Limbs can be in IK mode, which preserves the original end positions, or in FK mode, which maintains the bone angles.

Because of the way the motion is retargeted, it is important that the data be scaled to as close to the size of your rig as possible.

Further tweaking can be achieved with an adjustment layer.

Tip CAT uses retargeting to retarget the legs. This means that you will usually want retargeting for a leg to be set to 1.0. As an alternative you can leave retargeting off and reposition the pelvis/FootPlatforms with a World Adjustment Layer.

TipIf your data describes a character falling over or otherwise leaving the ground, you would generally blend the legs to FK.
