More info See in Glossary telling you that an AnimationClip is a good candidate. Unity currently supports three UI systems. You will have a Green Light in the UI (User Interface) Allows a user to interact with your application. Only AnimationClips that have similar start and stop Root Orientation should use this option. This means that the Game Object will not be rotated at all by that AnimationClip. The Root Orientation will be constant and delta Orientation will be identity. Root Transform Rotationīake into Pose: The orientation will stay on the body transform (or Pose). For example you can decide if you want the motion Y position to be part of the Root Motion (trajectory) or part of the pose (body transform), which is known as Baked into Pose. Depending on these settings some parts of the Body Transform may be transferred to Root Transform. The Animation Clip Editor settings - Root Transform Rotation, Root Transform Position (Y) and Root Transform Position (XZ) - let you control the Root Transform projection from the Body Transform. The circle below the character represents the root transform Animation Clip Inspector This change in transform is then applied to the Game Object to make it move. At every frame, a change in the Root Transform is computed. The Root Transform is a projection on the Y plane of the Body Transform and is computed at runtime. Everything else: muscle curves and IK goals (Hands and Feet) are stored relative to the body transform. They are the only world-space curves stored in the Animation Clip. More info See in Glossary set up in the Avatar). When an Avatar is in place, the Animation system works in muscle space, which is more intuitive than bone space. More info See in Glossary (using the Muscle definitions This allows you to have more intuitive control over the character’s skeleton. It is a simple “unit” piece of motion, such as (one specific instance of) “Idle”, “Walk” or “Run”. The Body Transform and Orientation are stored in the Animation Clip Animation data that can be used for animated characters or simple animations. The required pose for the character to be in, in order to make an Avatar. More info See in Glossary T-Pose The pose in which the character has their arms straight out to the sides, forming a “T”. The Body Orientation is an average of the lower and upper body orientation relative to the Avatar An interface for retargeting animation from one rig to another. More info See in Glossary engine and provides the most stable displacement model.

It is used in Mecanim’s retargeting Applying animations created for one model to another. The Body Transform is the mass center of the character.
