VoidFlow
by Makses580_
VoidFlow limits how far fluids spread when they flow over void space, so water and lava stop instead of forming endless columns.
What it does
Fluids that run off a ledge into open void keep falling in a column until they reach the bottom of the world. VoidFlow stops that flow. A global maximum fall distance applies to every fluid by default, and each fluid can be given its own limit, for example water stopping after 5 blocks and lava after 3. The settings sit in a configuration system that controls how each fluid behaves.
Limits can be narrowed with filters. Entries accept wildcard patterns for mod IDs, and filters work as either a whitelist or a blacklist. Universal Mode is optional: it applies the fall limits everywhere, not only over void. The mod is server-side only, so a server can run it without any client-side installation, and players join without it. VoidFlow is published for NeoForge 1.21.1 and is not open source, under All rights reserved.
Key features
Per-fluid fall limits
A global maximum fall distance can be set, then overridden for each fluid, so water and lava can stop at different depths.
Wildcard filters
Whitelists and blacklists accept wildcard patterns for mod IDs, letting a server target whole groups of fluids at once.
Universal Mode
Limits can be applied to every fall, not only the ones over void, when the server owner enables the option.
Configurable behavior
A detailed configuration file controls how each fluid behaves, so server owners can tune the result to their world.

Use cases
Void-world servers
Servers that use void or floating-island terrain can keep fluid columns from running down to the bottom of the world.
Modpacks with custom fluids
Pack makers can set fall limits for fluids added by other mods by matching their mod IDs with wildcard patterns.
Who it’s for: Server owners and modpack authors running NeoForge 1.21.1 who want fluid flow limited over void. Players on a server that runs VoidFlow need no installation.
