Modern Beta Forge

A port of Modern Beta Fabric for Forge 1.12.2!

Enjoy all the toggle-able features of Minecraft 1.12.2 with the faithful re-implementation of the Beta, Alpha, Infdev, and Indev terrain generators. Originally done for a friend's server but now expanded on to match the original Fabric version in feature parity plus additional improvements/fixes. Please don't expect updates beyond bugfixes and minor improvements if I feel like it.

Server Usage

The following should be done in the server.properties file:

• Set the 'levelType' field to 'modernbeta' (or 'modernbetacubic' if using Cubic Chunks), without the quotes.
• Set generation options in the 'generator-settings' field. You can create the generator options string using the in-game GUI.

Mod Support

Additional support is provided for these mods:

• Biomes O' Plenty
• Buildcraft Energy
• Cubic Chunks - Supported for height extension.
• Defiled Lands
• Depths Update - Supported for height extension.
• Dynamic Trees
• Future MC
• Millénaire - Download config files here
• Oceanic Expanse

These mods are known to cause issues:

• Galacticraft - Sky/Fog visual features will be disabled when this is installed.
• Muon - This mod is incompatible.
• Cave Generator - If you are experiencing tick/entity lag, please disable all biome replacement options to improve performance.

Add-ons

Modern Beta supports custom add-ons. Here are a few:

• Modern Beta Forge Release Plus - Adds biome generators from late Beta to early Release versions of Minecraft.
• Modern Beta Forge Islands - Adds island generation for several terrain generators.
• Modern Beta Forge Rivers - Adds river generation for several terrain generators.
• Modern Beta Forge Voronoi Climates - Adds biome generation with customizable biome maps and a visual editor.

Other recommended mods:

• Smooth Menus - Increases frame rate for in-game menus, including the customization GUIs.
• Celeritas

Preset Note

For accurate generation for non-Beta chunk sources, please select from the built-in presets first; simply changing the chunk source will not accordingly update the needed noise settings.

Why no Forge version for current versions of Minecraft?

I have no plans on working on current versions of Minecraft at the moment. Please take a look at Moderner Beta for an alternative!
