## Character Animation SO

If the Character Animations SO prefab is not compiling correctly: please message GVS.

## OnTriggerExit()

If you are trying to use Unity’s OnTriggerExit method, note that this is called if ANY part of the collider leaves the trigger area. The iMove player’s collider is intentionally placed down into the ground so that dynamic platforms can easily detect the player. To have the OnTriggerExit method behave correctly, you need to make sure it goes far enough below the ground so that the player’s collider is all the way within the trigger collider.

## Animator Controller

If your character isn't moving and stuck in the T-pose, this means the Animator Controller is likely missing from the Animator component of that character prefab. This can happen when assigning or creating a new animator controller. Ensure the animator controller on the Animator is the same one as the iMove Character Set up.
