Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

World Preview Prime

World Preview Prime is a continuation of the World Preview mod that adds a seed viewing map directly into the game. Preview and find a seed before you create a world, or review a seed after you've already created a world with it!

World Preview Prime was forked from the original mod due to inactivity from the original developer. This fork will both continue updating to newer versions and improve on datapack/config configuration.

Credits

Thank you to caeruleusDraconis for making the original mod. I will always question how you made this mod and remained sane, the code is terrifying.
Thank you to ChocoBoy for the initial port to 26.1 and adding full Lithostitched compatibility. I would have gone insane if I tried it myself.

Usage (Preview)

If you wish to preview a world seed, go to the Create New World screen and click on the Preview tab.

The most notable change from the original mod so far is the colors: World Preview Prime uses the same biome colors that you would see on Chunkbase or Cubiomes. On top of that, the structure icons now use blocks and items rather than custom textures. They're larger and easier to see, too.

Usage (Review)

If you wish to review a world seed, press the World Preview button in the Pause Menu.
