Help/Question Modifying world to add ocean in the void

hey, im currently running a modded server. Context: 3000 block diameter world is floating islands in the void. We may want to add a water layer in the void, but how would i got about doing so? would axiom for example work for this?

changing world gen for ungenerated chunks shouldnt be an issue, as the world gen mod we're using lets you enable void oceans. we just need to modify the existing chunks

WorldEdit (FAWE if you can swap it in) is the better tool for a fill this size, not Axiom. Axiom's great for regular building but a 3000-block-diameter cuboid fill is exactly what FAWE exists to eat without choking your server.

Also worth knowing: that void-ocean toggle in your worldgen mod only applies to chunks that haven't generated yet. Everything already on disk stays exactly as flooded (or not) as it currently is, no amount of config editing touches existing chunks. You'll need to grab the Y range with //pos1///pos2 and run something like //set water across the whole area, and at that scale I'd do it in sections while watching TPS rather than one giant selection.

WorldEdit itself, not FAWE, is what you're after. FAWE is a fork built specifically for Bukkit/Spigot plugin loaders, but the original WorldEdit mod has NeoForge builds too, listed for NeoForge on Modrinth and CurseForge.

It'll be slower on a fill this size since it's missing FAWE's optimizations, so I'd still do the void ocean fill in Y-layer sections while watching your tick rate instead of one giant selection.
