# Check Prefab/Scene Validity Button

The Check Prefab/Scene Validity button will analyze the prefab/scene for valid scripts and objects and if any of the objects in the prefab go outside of the bounds of the hexagon or folder. The Prefab/Scene will also be checked to ensure that there is only one OvrAsset in scene and no other external root objects. 

A popup will inform the user about the result of the check.
