This article needs to be updated to match TFC+'s newest version.
It might not contain completely accurate information for the newest version. Please help by contributing.

Compatibility & Performance

TFC+ should work on any system which is capable of running Minecraft 1.7.10 and Minecraft Forge.

TFC+ places a much higher load on your computer's processor than vanilla Minecraft and uses more memory as well, so performance may suffer on low-end systems. If you are having issues with lag or FPS, try the tips listed at Performance Optimization.


Why is the game crashing with a message saying TFCOre.cfg is invalid?

If you've played Terrafirmacraft before and then tried installing Terrafirmacraft+, the game may crash with the following error: "Error: java.lang.NullPointerException: The following block entry in TFCOre.cfg is invalid: terrafirmacraft:Ore1".

This is caused by the existing config file from the previous TFC install conflicting with the new TFC+ install. Delete the existing TFC configs (TFCConfig.cfg, TFCOres.cfg, TFCCrafting.cfg). This will allow TFC+ to regenerate the proper config files.

Why does the game crash with "Unexpected Error"/renderer error when I try to join a world?

Your render distance might be too high for 1.7.10. Set it lower (16 or less).

Why do I have severe lag issues?

Lag in TFC+ is mainly caused by two things: world generation and smooth lighting.

World generation causes lag because when trees extend across the chunk boundary into an ungenerated chunk, that chunk must also be generated - but the new chunk may also have a tree that does the same thing. TFC+ has made some changes to tree generation to minimize this problem, but it still happens sometimes. Once the player is staying in chunks that have already been generated, the lag should be significantly less. Alternatively, you can consider playing on a server, so that your computer does not need to generate the chunks itself.

Due to the unique rendering of trees, undergrowth, and fallen leaves in TFC+, smooth lighting may cause lag issues. The simplest fix for this is to turn off smooth lighting or to reduce the amount of trees, underground, and fallen leaves around you. One can choose to turn off smooth lighting in forests and turn it back on in a plain.

Why am I seeing weird graphical glitches?

Glitches like missing water, virtual trees floating in the air, and roof corners not rendering correctly are frequently caused by Optifine. Disabling the Fast Math option, removing, or updating Optifine, might solve some of these issues. Consider using Fastcraft as an alternative.

What is TFC-TNG?

TFC-TNG (Terrafirmacraft-The New Generation) is not TFC+. It is the project to port the original Terrafirmacraft mod to MC 1.12 and beyond. The TFC-TNG wiki can be found here.

Can I update my TFC Classic modpack to TFC+?

This will likely not work. Because Terrafirmacraft+'s code is significantly different from Terrafirmacraft Classic, your addons and mods will likely break with Terrafirmacraft+. Addons must be specifically updated to work with Terrafirmacraft+. A list of addons that are known to have been made for Terrafirmacraft+ can be found at the Addons page.

Can I use my existing TFC Classic world in TFC+?

Terrafirmacraft+ makes many significant changes to world generation from Terrafirmacraft Classic. The two projects have significantly diverged such that updating from Terrafirmacraft Classic to Terrafirmacraft+ will likely break your world. Additionally, because many changes are focused on the early game, it is encouraged to start a new Terrafirmacraft+ world instead.

Is TFC+ available for 1.12?

Terrafirmacraft+ is only for 1.7.10. There are no plans to port TFC+ to other versions. Doing so would be too massive a task for the developer to do in his free time. Instead, he focuses on continuing development of the 1.7.10 version.

Is TFC+ a plugin? Do I install it alongside TFC Classic?

No. TFC+ is TFC Classic, updated with new features. Installing it alongside TFC Classic will cause a "java.lang.reflect.InvocationTargetException" crash.

Where can I find support for TFC+?

The Discord or Subreddit are active and open for your questions.

Twitch Installation

Follow the instructions here to create a modded Minecraft profile. When creating the profile, select Minecraft version 1.7.10. The default version of Forge is fine. When you get to the point of adding a mod, search "terrafirmacraftplus" and select TFC+ from the list.

Twitch App Listing.png

Alternatively, you can install the Baseafirmacraft profile, which includes many utility mods commonly used alongside TFC+.

Increasing Memory Allocation

To increase the memory allocated to the profile, click the gear icon on the top right side of the profile page. Select "Profile Options". In the window that opens, unselect "Use System Memory Settings". Then move the slider to the desired amount of memory and click "Okay".

Running TFC+ without opening the Twitch App

Once you have Launched TFC+ through the Twitch App, you can launch it again without using Twitch -as long as you haven't run any other instances of Minecraft in between. To create a desktop shortcut, naviagate to the default location where Twitch installs minecraft


and right-click on Minecraft.exe and select "Send to Desktop (Create Shortcut)"

Clicking the shortcut on the desktop will open the Minecraft Launcher set up for the profile last used by the Twitch App.

Default Path

If you want to manually add other mods or find your screenshots, the default path is:

Manual Installation

Start with a vanilla install of Minecraft 1.7.10 using the official minecraft install launcher located at

If your Minecraft Launcher is running 1.8+:

  • Select Installations
  • Click New Installation
  • Select Minecraft 1.7.10

Run once to create necessary files.

Download and Install Minecraft Forge

Download: forge-1.7.10-

Once downloaded, double click and run the .jar file. A screen will pop up. The install path should be the default install path that minecraft installed into. If so just click OK to install forge.


When finished you should see a screen pop up:


Run minecraft again. At the profile selection dropdown, select Forge, fill in any login information necessary, and finally press Play.

When you get to the main menu, exit out of Minecraft.

Download and Install TerraFirmaCraft

Version: 0.84.1

Download TFC+ from the link above and copy the .jar file into the Mods folder in the minecraft/forge install.

System Default Location of 'mods' Folder
Linux ~/.minecraft/mods
OS X /Users/yourUserName/Library/Application Support/minecraft/mods
See additional instructions for OS X users below.
Windows \Users\yourUserName\AppData\Roaming\.minecraft\Mods
You can get to this location quickly by typing in %appdata% into the location bar and navigate to .minecraft\mods\

Note: Do NOT unzip the file!

If you are on OS X then there are some extra steps you will have to take:

  • By default your Library folder is hidden and will not appear in the Finder. To make it visible, bring up a Terminal window and execute the following command:

    chflags nohidden ~/Library/

  • Depending upon your browser settings, when you download the TerraFirmaCraft zip file OS X may automatically unzip it and place it into a folder named 'TFC-0'. The download settings can be changed in your browser such that it doesn't unzip upon download. Find where your browser keeps its helper application settings and change the action of the zip file type to "always ask" or "save as."

TerraFirmaCraft should now be installed. Run minecraft again making sure your Profile is still set to Forge.
Once in game click the mods button and you should see something similar the following:


Shader Setup

If you are interested in playing Terrafirmacraft+ with shaders (via Optifine), there are some tweaks that you will need to make to the shaders so that they can recognize TFC+ water and leaves. Please see the Shader Setup page for instructions on how to set up shaders with Terrafirmacraft+.

Server Installation

A server installation of TFC+ has a few requirements.

First, you must have access to the files of the server or computer you wish to run the TFC+ server on. Certain hosts do not have this ability - so be sure that you have access to the files, or the ability to run mods on the host.

Second, the server must have Java installed. If you are making a server using a Virtual Private Server (VPS) host, you must install Java on the operating system you wish to install TFC+ on.

Third, for others to connect to the server, the computer must be port forwarded. If you are using your own computer to run a server, this is important.

Fourth, TFC+ itself and Forge must be installed.

This article covers the fourth step; the other three steps must be figured out on your own.


In this step, you will download the Forge Installer and TFC+.


Either Forge 1.7.10-1558 or Forge 1.7.10-1614 can be used. Download the Installer version of Forge.

Download: [1]


TFC+ can be downloaded from Curseforge.

If you are using a rented server, you must connect to your server in this step. If the server you are renting is running Linux (which is the default Operating System for most rented servers), use a SSH client to connect to the server. The exact specifics of installing a SSH client, connecting to the server, and basic usage of the server, is out of the scope of this article. However, this information can be easily found online.

Install Forge

Create a folder on your server computer where you want to start your installation. For example, you can use
(Windows), or

If you are running a server on your own computer, you can start the Forge Installer by running it with Java. Select "Install Server", and choose the directory you wish to install the server to.

If you are renting a server which is running on Linux, move the Forge Installer to the directory you wish to install the server to, and run the following command:

java -jar forge_installer_VERSION.jar --install-server

Run the server once, either by running forge_universal_VERSION.jar with the Java Runtime, or by using the following command:

java -jar forge_universal_VERSION.jar
The server may crash and ask you to accept the EULA; open eula.txt with an editor such as
, and change eula=false to eula=true. The server is now ready for TFC+ installation.

Install TFC+

Move TFC+ into the mods folder created when you ran the server. If the mods folder does not exist, create it, and move TFC+ into it.

Create Run File

Now, you will create a script to run the server with. On Windows and Linux, this will be
respectively. Use a text editor such as
to create the script.

Insert the following line into the script.

java -Xmn1G -Xms2G -Xmx2G -jar forge-1.7.10-

Starting up the Server

Run run.bat or If you are renting a Linux server, and are connected to the server via SSH, run the script using
. If you are running a server on your own computer using Windows, double click on the file to run it. On Linux, you may have to grant a permission for the file to be executed first. Do this by using
chmod +x
. The server can now be used.
