Creating Ocean World with an island

[paramat]

Add or edit this line in minetest.conf:
cloud_height = 120
EDIT

Is there any way of reverse engineering the mapgen to figure out the seed required to generate a flat or island world

Nope. Mapgen v6 can't generate a flat world or an island world, also its inherently impossible to generate seed from a desired noise.

Would you still be interested in a mod that creates a single island of chosen size in an 'infinite' sea? I'm getting interested, it's a nice idea, i think i can derive this easily from flatten mod.

Bump, I am interested in this.

LOL i never got around to it.
Perhaps you can work out how to customise my archipelago mod? currently 2D noise determines the areas lowered into the sea, replace that with a mathematical function based on distance from world centre, should be easy.

Line 191 https://github.com/paramat/archipelago/blob/master/init.lua#L191 'comfac' is 'compression factor' i think, that should be 1 within the island area and increase smoothly to roughly 24 in the surrounding ocean.
The mod will probably crash because it needs line 122 editing to:
