Additional Mods

From GT New Horizons

If you are looking for a backup solution, there is a detailed page here.

This page is about mods you can add to your GT New Horizons instance. They are all client-side mods, meaning you don't have to install them on a server when you are playing multiplayer. Exceptions to this are Aroma Backup and FTB Utilities, both of them can be installed on a server. You are most likely not going to want to install all of them because their features overlap to some extend. Important: you don't have to install any of these mods, the modpack runs just fine without them.

See also Resource Packs.


Note: This is not a list of mods contained in GT New Horizons nor a list of officially recommended mods. They may stop working at any time.

All mods must be put in the mods folder inside your modpack directory (see below).

Mods marked with [LL] require LiteLoader (see below).

Mods marked with [FL] require FTB Library.

Name Description Conflicts
AlkGuiHider-1.1.jar Allows hiding certain GUI elements (useful if you are using InGameInfo instead)
Archaicfix A number of bugfixes, tweaks, and optimizations for Minecraft 1.7.10. Crucible/Thermos/etc. are not supported.
Possible crash with GTNH v.2.3.0 has been reported.
Better Foliage Enhances the appearance of grass and leaves.
Better Rain Better Rain changes the sound and texture of rain depending on the "strength" of the rain. The strength is random each time the weather changes to rain/thunder.
Big Chat History [LL] Extends your chat history from 100 to 10,000 lines. If TabbyChat 2 is installed this mod will do nothing.
Chat Bubbles [LL] Displays chat bubbles over the player heads when they type something in the chat. If you are playing on a server with plugins thy might handle the chat differently (using plugins) and the mod might not work. Check the mods' homepage for that.
CleanView This mod removes the visual particles of potion effects (The actual effect will still be active).
ClientFixer This can be recommended for use by those who play in Russian (or in another language using the cyrillic) for correct display of the font at different interface sizes and for the correct display of Thaumcraft inscriptions
Damage Indicators Adds a HUD that shows information about health, effects, if it's hostile and a 3D image of the mob you are looking at. - The HUD is positioned in the top left corner so it might overlap with InGameInfoXML.

- The information about health doubles with WAILA so you might want to change the WAILA config.

DE Config Integration Integrates many items with the Draconic Evolution tool and armor configuration GUI. Required on the serverside for MP.
Dynamic Surroundings A compilation of Better Rain, Aurora Rubealis and Presence Footsteps. Rendering issue when Optifine is installed aswell. See Issue #8374.
Fancy Block Particles Breaking a block now creates 3D particles. Incompatible with the Twilight Forest dimension.

Change fancyRain and fancy Snow in config to false.

Forge Essentials The ForgeEssentials project consists of many server features,

especially a powerful permissions and protection system:

Permission management.

Protection (WorldGuard).

Automatic backup management.

Multiworld support(in bukkit aka. multiverse).

Huge collection of utility commands.

Remote server access and management with a versatile API.

WorldEdit with permission integration already included.

And many more!

If your using java 17+ make sure you are using the most up to date version of forge essentials. You can find this on either the forgeessentials discord in the dev builds channel or through the github page, but you need to be logged in.

Make sure to rename the GTNHMixins jar file to start with a number or a dash. (Future versions replace that mod with unimixins, make sure you do the same thing there).

If you are using a previous version of forge essentials (1373 and below) then make sure to include the launch argument -Dnet.glease.healer.patch_stage=POSTINIT before the -jar (or @java9args.txt).

FPS Reducer Reduces the CPU/GPU load when you are AFK or Minecraft is running in the background. In this case the mod suppresses the game sound.
FTB Utilities [FL] Replaced by Server Utilities, see below. Backup your world scheduled or via command. Add other players as friends and give them permissions to your claimed chunks which also can be chunkloaded. Don't forget FTB libs. Needs to be installed on the server and client-side for MP.
Just Enough Calculation Store recipes and get a "total material cost" for a given over-all recipe. Client-side only, so can be run against a server. Note the keybind comments. Documenation
ItemPhysic Lite Adds physics to items dropped on the ground. This is only visual as the full version must be added to the server too. Some items do not work.
Fullscreen Windowed Replaces the fullscreen mode with a borderless windowed mode. May display the window incorrectly and obstruct large portions of the screen when used with a desktop resolution created by NVidia DSR.
Link Info [LL] Provides basic information about the link you clicked on:

YouTube: video-title, uploader, thumbnail

Image: can show you the image ingame

Other: title of the website

MAtmos Atmospheric sound generator. It will play sounds according to your surroundings. If you are in the forest - birds will chirp. If you are at low health - you will hear your heart beating. The Soundpacks must be put in the "resourcepacks" folder in your modpack directory (see "Finding the modpack-directory"). - The "MAtmos"-key (F7) conflicts with the default "Mob Spawn Overlay"-key from NEI. You have to change one of these.
NEI Easy Search Provides a better NEI search experience for chinese characters. The game can crash when using this mod alongside mitchej123's modified NotEnoughItems.
Neodymium Better chunk rendering using modern OpenGL. This should improve performance on most hardware. Make sure to use the nomixin variant of the mod, the other might conflict with GTNH. Might not work with certain optifine settings. Performs poorly if Advanced OpenGL (occlusion culling) is turned on.
NoFog Removes all fog.
NotFine Extra video settings. An open source alternative to optifine. Do not use with optifine or the leaf culling mod.
OptiFine OptiFine is an optimization-mod that increases the performance of the game. Additionally, it provides a lot of features like shader support, VSync, connected textures and a lot of video-settings. If you consider using this, read this before installation. Otherwise you are likely to encounter problems. E7 is better for shaders, but version D6 may be better without shaders. - Note: Optifine D6 does not work with the Java 17-20 version of GTNH.

- Fastcraft 1.23 conflicts with Optifine, you have to upgrade to 1.25 or remove it. - Fastcraft 1.25 has non-critical conflicts with Optifine E7 when shaders are enabled. Some shadows may be rendered incorrectly (flicker).
- Depending on your hardware "Chunk Loading" in the Video Settings has to be set to "Default". If it does not, your game can crash if you join a world/server.

Dynamic Lights This mod adds more realistic lighting mechanics such as torches glowing while you hold them in your hand, throwing a glowing object on the ground will light up the area, mobs on fire will emmit light, XP orbs glow as well ect. Since GTNH has hardcore darkness, this mod will ease your life in caves and at night. Optifine has built in dynamic lighting so this mod isn't needed if you have already installed Optifine. Causes certain NEI related bugs.
Presence Footsteps [LL] Alters the way footstep-sounds are played when sprinting, jumping or walking on two different blocks at the same time.
Server Utilities Replaces and updates both FTB Utilities and FTB Libs and will migrate existing configs. Includes Journeymap integration for chunk unloading.
Smooth Font Optimizes the way text is rendered and provides options to scale the text and change the font. When using FastCraft "enableFontRendererTweaks" has to be set to false.

In order to make your new font choice compatible with BetterQuesting, make sure to configure BetterQuesting (Pause -> Mod Options -> BetterQuesting -> general) and set Text Width Correction to something like 1.1 or 1.2 (Source)

Sound Filters Adds reverb to caves and muffles soundsources when you are behind a wall or under water. Possible incompatibility with Java 19 and/or the Java17-20 version of the pack. More testing required for Java 17, 18, and 20. Crashes when loading world on Java 19. Also crashes when loading world on Java
TabbyChat 2 [LL] Completely overhauls the chat window. Resize the chat how you like, create channels/private messages, add filters, see timestamps... If Big Chat History is installed it will do nothing.
VoxelMap [LL] A minimap. It has the same basic functionality as JourneyMap but with some addtions: choose icons for your waypoints, share waypoints and have a monster-radar even in multiplayer (technicaly JourneyMap has a radar aswell but not in the version shipped with GTNH).
WorldEdit for GTNH GTNH fork of WorldEdit, which allows copy, cut, paste, alteration of blocks on a massive scale, easy terrain painting and more.


LiteLoader is a modloader like forge however it supports mods with the .liteloader file extension. The installation is similar to Forge but if Forge is already installed (which it is because all mods within GTNH work with Forge) that does not work. In this case you can install LiteLoader as a Forge mod (.jar file extension). To do that run the LiteLoader installer and select "Extract LiteLoader jar". Then choose the mods-folder inside your modpack-directory (see "Finding the modpack-directory") as the extraction-directory.

You have to insert .liteloader mod-files in the mods-folder in your modpack-directory.

How to extract the LiteLoader .jar for use with Forge.
