Random Creature Sizes Mod (NEW UPDATE) screenshot

About this mod

Features

  • Randomized creature scaling system using a weighted bell‑curve distribution.
  • Size range from 0.2x to 30x by default; configurable for more natural scaling.
  • Supports every fish, creature, and leviathan currently in the game.
  • Size‑based movement speed scaling (larger = slower, smaller = faster).
  • Species synchronization support and physics‑safe scaling caps.
  • Leviathan Event and Super Leviathan Event systems with configurable chances.
  • Configurable hotkeys (default F5 enlarge, F6 shrink, F9 Leviathan, F10 Super Leviathan).
  • Automatic world sweep system rescales newly loaded creatures.
  • Persistent scaling after spawn; logging and optional speed‑scaling toggle.
  • Full editable configuration: global ranges, per‑creature overrides, event multipliers, sweep intervals, keybinds, and synchronized species groups.

Requirements

  • UE4SS must be installed and mods enabled.

Installation

  1. Download the mod archive.
  2. Extract the folder into the Subnautica 2 mods directory.
  3. Launch the game, start or load a save normally.

Configuration

The mod includes a fully editable configuration file. You can adjust:

  • Global scale ranges and individual creature overrides.
  • Minimum/maximum species sizes.
  • Leviathan event chances and multipliers.
  • Keybinds and sweep intervals.
  • Speed‑scaling behavior, logging, and synchronized species groups.

Fallback defaults are used automatically if the config is missing or broken.

Compatibility

  • Works with the current Subnautica 2 build; requires UE4SS.
  • Known to be compatible with other UE4SS‑based mods, but test for conflicts.

Known issues

  • Newly loaded creatures may briefly appear at normal size before the sweep rescales them.
  • Void Leviathans automatically synchronize scaling between female and male variants.
  • No multiplayer support yet; planned for future updates.
