A configuration is specific to an animation system.
A configuration defines the parameters used by the animation system.

.. _IKConfig:


Configurations for IK Systems
_____________________________


Each configuration for the IK systems uses a different amount of trackers. 

The default configuration uses three trackers: two for the controllers and one for the headset. Other configurations require additional trackers. 

A tracker is a GameObject that represent the position of a tracked body part. It can either be the object moved by the XR tracker, or a child of that object if an offset is needed.

| To define a tracker, you can either drag and drop the target object from your VRRig, or use the :ref:`ToolXRRigHelper` tool.

.. _ReplayConfig:

Configurations for Replay Systems
_________________________________

There are three configurations available for the replay animation system:

- Replay Animation clip: use this configuration for Unity animation clips.
- Replay AvatarReady animation file: use this configuration animation recorded in the json format.
- Replay Animator controller: use this configuration to replay animations using a Unity Animator. 

Once a configuration is selected, the option field for the animation file to use will be displayed. 
The folder used to search animation files is defined in :ref:`Settings`.
