RealSize

RealSize makes Minecraft mobs feel closer to real-world sizes. Bees can be tiny, horses can feel properly large, and server owners decide how far to push the effect.

It is a server-side Fabric mod for servers and modpacks that want more believable mob scale without making small mobs vanish or large mobs get stuck on every little bump. RealSize uses Minecraft's scale attributes, adds extra tracking help for tiny mobs, and gives oversized mobs a small step-height boost so they move through terrain more naturally.

What it does

• Resizes mobs from a simple JSON config at config/realsize.json.
• Lets server owners set per-mob scale values with registry IDs like minecraft:bee or minecraft:horse.
• Keeps very small mobs visible from farther away by increasing their tracking range.
• Helps large scaled mobs step over terrain instead of snagging on small blocks.
• Supports both the current PyreHaven 26.x target and Minecraft 1.21.1 through 1.21.11 with separate jars.

Good to know

• Server side: install it on the server. Players do not need the mod on their client.
• Loader: Fabric.
• RealSize writes config/realsize.json the first time it runs.
• Config changes apply after a restart.

Configuration

Start the server once with RealSize installed, then open config/realsize.json.

You can adjust the global size limits, tune when tiny mobs get extra tracking range, tune when large mobs get extra step height, and set individual scale values for specific mobs.

Example entries use Minecraft registry IDs:

"entityScales": {
  "minecraft:bee": 0.25,
  "minecraft:horse": 1.05,
  "minecraft:nautilus": 0.4,
  "minecraft:zombie_nautilus": 0.4
}

Practical uses:

• Make bees tiny without losing them at normal viewing distance.
• Keep oversized mobs from getting absurdly large by lowering the scale cap.
• Help larger mobs move over terrain more naturally by adjusting the step-height settings.

Installation

1. Pick the jar for your Minecraft version.
2. Drop it into the server's mods/ folder with the matching Fabric Loader and Fabric API modules.
3. Start once to generate the config.
4. Edit the config if needed, then restart.
