I'm not the best scripter, so I dont have a platform for this, but the basic idea, is a script in Workspace/serverscriptservice that finds a block in Lighting and generates each block anywhere in a sppecific location, just like the Quarry by Dummiez. Thanks for helping. EDIT: Heres some code I know
game. Lighting. BLOX: clone()
.....
BLOX.Vector3.new: X:1 Y:1 Z:1
Bad scripting alert.

I suggest that, before you ask about generating a 3-dimensional grid of blocks, you first make sure to have read the Absolute Beginner's Guide to Scripting on the Official ROBLOX Wiki and know how to do basic things with CFrame and Vectors. The 'code that you know' is nonsense, it doesn't make any sense.
Alright, THANKS
