A plugin that will disable chunk spawning?

I've created a flat-world hub for my server. I want to delete the current chunks around my hub and disable chunk spawning in that entire world.

Is there a plugin that will do that for me, or do I have to use an external program on the world such as MCEdit?

 

What's 'chunk spawning'?

 

Chunk spawning = when chunks spawn/generate.

Two ways:
- Set movement borders per world with something like WorldBorder.
- and/or -
- Use a terrain generator like Cleanroomgenerator to generate empty space instead of natural terrain.

 

You could use WorldBorder to set the limit, or you could use WorldPainter to create a hub world the size you'd like, and have it generate void for "x" number of tiles around the edge of the map. For a small hub, I would set the size to 2x2 tiles, make it the shape you want, and then put void around it. Set the map border to void and have it generate 2 tiles outside the map border.
