It is common when creating scenes to reuse the same objects in the same scene or between different scenes.
To avoid having to create the object again LiteScene allow to create prefabs.
A prefab is a description of a SceneNode (its properties, components and children).
By creating a Prefab you can store that node info as a resource and invoke it whenever you need it.
You can create prefabs by code or using the WebGLStudio editor.
