Hey All,
I recently started working on a project where including reflection of other objects in the scene was desirable on high end devices so I started looking into ways to achieve that, when I came across this official example from playcanvas: PlayCanvas Examples
But I have a habit of understanding project better when I see it in an editor. So I recreated the exact same project in the editor. Turned out to be pretty useful for me with the implementation.
Sharing the project here just in case someone is looking for a similar resource in the project:
BoxReflection-InEditor Examples
Hope this helps someone 
Have a Great Day!!
