Sky box block for map making.

Make a creative only block like barrier block or light source block. This block is also invisible like the barrier block and still behaves like the barrier or light where you hold it and you can see where they are. The change with this block is that it makes anything behind it effectively invisible. All you see is the sky box through the block. I imagine this would be very helpful for map makes. I’m currently working on a build in creative that is a bunch of arenas and this would help a lot. I could prevent the player from seeing behind the scenes without needing giant ugly stone walls and work arounds. 

If you are truly up to go the extra mile: Make a version of the block that connects to a counter part. The block will show what ever is around that counter part instead of just the sky box. Say I was mad and I still wanted a big ugly stone wall to bee seen but I wanted it to be of a uniform shape and distance. I could use this to have the appearance of the wall, no matter how close it is.
