NOTICE: If you use FAWE with " tick limit per chunk " option, generation of walls with falling blocks (such as SAND) may case incomplete walls. 

Since there is not any instant wall generator plugin that does what I wanted, I made this...

How it works:
You first obtain an instawall bucket (with a certain material such as COBBLESTONE, OBSIDIAN), then you pour the material as you place the block.  The material will start running down as long as AIR space underneath or no Sponge blocks nearby. The pouring will stop once the material hits the non-AIR block.

You can give players/groups permission nodes to use any particular types (material types) of InstaWall buckets.

You can also specify the worlds where the use of InstaWall buckets is disabled.

Sponge:
If there are sponge blocks nearby the path of a block being dropped, the material pouring will no longer proceed. Just like the regular behaviour of the sponge against water.  However, sponge blocks will not be able to absorb already materialised blocks.
