About this project
What does Not an Empty World add?
Not an Empty World

An atmospheric mod where your world slowly starts to feel off.
The mod adds events that happen in your survival world over time. At first they are small and easy to miss, like footsteps or a door left open. Later they get more noticeable, and a figure starts showing up.

Changes to your game
Spoiler
The mod changes the render distance setting, can deliberately crash the game in single-player, open your world to LAN, save an image to your screenshots folder, and change blocks around your base. It also spawns far fewer animals and no naturally spawning hostile mobs. All of this can be turned off in the config.
The mod never touches files outside your instance folder.
How long to play
About an hour to an hour and a half in one world.
Recommended mods
- Golden Days Base (resource pack)
- Nostalgic Tweaks (mod)
Compatibility
- Shaders can break the fog.
- Lowers the Overworld's minimum build height. If another mod changes world height, turn off Common → Lower overworld floor.
Requirements
Minecraft 1.21.1, NeoForge, Java 21
Modpacks
You can use the mod in any modpack, as long as the pack downloads it from this page. Please don't re-upload it.
