Note: The toolkit requires Unity 2020.1 or greater.
Unity 2020.3 and greater now ship with Newtonsoft Json.NET. If your Unity project already includes Json.NET, you may get errors in the Unity Console due to duplicate function/class definitions. In most cases, removing the Babylon Toolkit copy of the of the Json folder (Assets/[Babylon]/Plugins/Json) should solve the issue.
