Walk generator
by Yassou
Walk generator reveals terrain one block-wide column at a time, as a player walks through an otherwise empty NeoForge world.
What it does
A playable world begins almost completely empty. Each time a player steps onto a new block position, the vertical column of terrain beneath that position is copied from a naturally generated Minecraft world and shown. Caves, ores, biomes and structures appear progressively under the player's path, and the revealed columns stay visible after the server restarts.
Revealed terrain is shared between players on the same server, so one explorer makes a path visible to everyone. A global column-generation limit, which the server owner can configure, keeps the workload controlled when several players reveal different paths at once. Collision protection also brings terrain in near the player. Overworld, Nether and End are all supported.
The mod runs on NeoForge for 26.2 only. Client and server both need it, and the latest file is 0.1.2, published on 2026-10-05. The project is an experimental early version, and the author recommends backing up the world before updating. It is released under All rights reserved and is not open source.
Key features
Column-by-column terrain
Each step reveals exactly one block-wide vertical column along the player's path, copied from a natural world.
Shared exploration
On a shared multiplayer server, once one player uncovers terrain, every other player can see it too.
Persistent reveals
Revealed columns are saved permanently and remain in place after the server restarts.
Global generation limit
A configurable cap on how many columns generate across the server keeps the load manageable with many players.

Who it’s for: Players and server owners who want exploration in a world that fills in only along the paths players take. The mod is experimental and is suited to testing rather than long-term play without backups.
