WorldPreview
by voidxwalker
During world generation, WorldPreview draws a live preview of the chunks that have finished loading, shown on the loading screen for speedrunners and other players who watch new worlds take shape.
What it does
The Fabric mod renders a preview of the world while the game generates its chunks. It converts chunks already completed on the client into a map and draws it on the loading screen, so a player can see which parts of the world are ready. Its preview always renders when a new world is created and does not change how generation itself works, so the world produced is the same as without it. The client alone runs it, so servers and other players need nothing installed.
The mod targets speedrunning and runs that must be verified. A full chunk map shown during recording helps show that a run was legitimate, and the run count is shown on the F3 + Esc pause menu. Its author states that it is compatible with newest releases and with the spawn reset macros of specnr and FinestPigeon, as well as the ssg macro. Release files cover 1.14.4, 1.15.2, 1.16.1, 1.16.5 and 1.17.1, with 2.3.3 for 1.17.1 as the latest published file. The mod is released under the MIT License and is open source; its source code is public.
Key features
Live chunk preview
The loading screen draws the chunks generated so far, giving a view of world generation as it happens.
Five ways to interact
Players can use direct inputs, the F3 + Esc combination, or hotkeys to control how the preview behaves.
Chunk map cycling
The default hotkey h cycles the chunk map through four positions, and the j key freezes the preview to ease CPU load.
Instant exit
A hotkey and a Save and Quit to Title button both leave the world generation screen immediately, with the g key as default.
Hotkeys in the Controls screen
The preview hotkeys can be changed on the Controls screen, so the defaults can be replaced.

How it compares
WorldResetter is server-side only and open source under the MIT License, with files for 1.21.11 – 26.3, so it targets a different stage of the same workflow. Chunk By Chunk is client and server, open source under the MIT License, and covers Fabric, Forge, NeoForge and Quilt for 1.17.1 – 1.20.4, so it works on a server and on several loaders where WorldPreview runs only on Fabric on the client.
