Old (and not so old) world generation for modern Minecraft!

Part of the Nostalgica Reverie project


Welcome to Moderner Beta! This is a fork of b3spectacled's Modern Beta that started out as a pull request but due to the original creator's inactivity has been published as a fork. Alongside all of the world generation options from Modern Beta, this fork adds in world generators from Beta 1.8 all the way up to Release 1.17 which are highly customisable with plenty of configuration options. The goal of this fork now is to pick Modern Beta's development back up and add in extra features.

Notice

Moderner Beta 5.0.0 is currently in alpha. There may be bugs and issues, and can be prone to breaking with future releases. 4.1.x will continue to be supported until 5.0.0 exits development. Development may take quite some time. If you could help, then please consider applying as a developer here.

How to Report Issues

Please use the issue tracker linked at the top of the page if you are experiencing bugs, crashes, or other issues.

Features

Moderner Beta has a quite extensive feature-set and many benefits over the original Modern Beta mod!

What Modern Beta offered:

  • World generation for various old versions of Minecraft ranging from Classic 0.30 to Beta 1.7.3
  • A range of custom options to modify terrain shape and biome distribution

What Moderner Beta offers:

  • Support for NeoForge and Forge in addition to Fabric
  • Graphical settings menu for simple options
  • World generation from Beta 1.8 all the way up to Release 1.17.1 with accurate biome distribution
  • Additional world generation from Infdev 20100325, Classic 0.0.14a_08 and Beta 1.1
  • Re-introduced noise caves and surface rules
  • Extremely customizable biome fractal layer pipeline for Beta 1.8+ versions
  • A modular approach to configuration that gives greater control to addons

Documentation

To learn about all of Moderner Beta's configuration options as well as find some answers to some frequently asked questions, go to the official wiki at https://moderner.nostalgica.net/docs.

Additional add-ons

For the authentic early release look, use a resource pack like PACP to add the programmer art style to newer content and use Sodium Extra to thicken the fog by turning down the fog start multiplier to 25% (or 75% if a 1.7-1.17 look is desired).

For a beta-style look, use a resource pack like Golden Days and use Nostalgic Tweaks to further restore old mechanics and visuals.

Credits Thanks to icanttellyou for porting the mod to various platforms.

The Nintendo Switch Edition decompilation project has been referenced to implement accurate LCE terrain generation.
