The PlayCanvas team is very excited to announce the public release of our new Templates feature! 
Templates allow you to create preconfigured entities with all the values and child hierarchy as an asset reference.
This is a huge workflow boost as managing and changing objects in a scene is now easier and faster to do. New instances of the Template can be placed in the scene with the Editor. These instances have a link to the Template asset, so any changes to the asset will change the instances in the scene too.
