Island seed

[Virtuuous]

I'm trying to figure out a way to query seeds with something like 90%+ Ocean biome within 1000+ blocks in any direction of spawn. Is there a way of doing this?

To achieve that, you can employ a systematic approach involving the use of a sufficiently large square grid of surface height conditions.

Personally, I would create a grid of conditions that ensure you're within the desired range of the Ocean biome. In Minecraft, the surface height for an ocean biome falls within the range of [-64, 62] blocks. Therefore, you'll want to set up a grid of height conditions that cover this height range. Keep in mind that there is a limit of 100 conditions in Cubiomes, so you'll need to strike a balance between grid resolution and area size. Another problem is that creating so many conditions is cubersome with Cubiomes (I automate that part by creating the hexadecimal #Cond in the session file programmatically with Python and loading the generated session file).

An example of such seed would be 605378.
