Mod Compatibility (GregTech 5)

This page documents some of the compatibilities/incompatibilities of some mods with GregTech. You might want to go here to read about the changes GregTech does to Vanilla Minecraft and Vanilla IndustrialCraft 2 (also known as IC2) first.

By default, GregTech only modifies Vanilla and IC2. However, GregTech makes use of the Ore Dictionary. Thus, some changes might have effects which seem weird for the user. For example, GregTech nerfs the default wood->plank->stick crafting, which might affect other mods that add different types of wood.

Please note that this article will be written from the point of view of somebody who has no idea what a program is and what it does. If you are an advanced user, this article will serve as a good reference but some of the information may not apply to you.

Compatible Mods
Compatible Mods are mods that interact with GregTech to provide more content when they are both installed fall under this category. These mods are mods you might consider adding to your modlist if you have GregTech installed.

Per Fabrica Ad Astra Geologica
Per Fabrica Ad Astra Geologica, or PFAA, is compatible with GregTech. GregTech disables its own ore generation if it detects that PFAA is present. All of the ores that are not generated by PFAA will be generated by GregTech in the Nether and/or the End. PFAA will also use GregTech ore names if it detects that GregTech is present.

CodeChickenLib
CodeChickenLib is useful to have as from GregTech 5.01g. GregTech needs this mod to show a more detailed overlay when you have a wrench in your hand. This will definitely help many new players get used to GregTech's wrenching mechanics.

If you are going to install CodeChickenLib, you might as well install NEI. CodeChickenLib will automatically be downloaded for you after you install NEI.

Semi-compatible Mods
Semi-compatible mods are mods that "play nicely" with GregTech. These are mods that do not go out of their way to provide more content to GregTech users. Mods that you can easily get to work with GregTech with some light config editing will also fall under this category. Most Forge mods will be semi-compatible by default and as such this wiki will not document all of them. Here are some things to keep in mind about some of the more popular GregTech semi-compatible mods.

Railcraft

 * Railcraft Steam is accepted by GregTech.
 * Railcraft's Blast Furnace makes steel quicker. However, building it requires going to the Nether. Due to the flint and steel recipe change, you need to build GregTech's own Bronze Plated Blast Furnace before going to the Nether; unless you manage to light a nether portal without flint and steel.
 * GregTech adds its own multiblock Boilers as from version 5.01i. These have their own mechanics and are different from Railcraft's Boilers. You might want to do some research before choosing which boiler better suits your needs.

Incompatible Mods
Incompatible mods are mods that might require experimenting on your own to get working with GregTech. Mods that require heavy config editing or writing a mod yourself to fix the problem will also fall under this category. You are basically on your own if you wish to play with these mods and GregTech.

Tinkers' Construct
Tinkers' Construct would have been semi-compatible with GregTech, except for how Tinkers' Construct names its Aluminium ingots. GregTech calls its Aluminium Aluminium, which is the preferred IUPAC name. Tinkers' Construct calls its Aluminium Aluminum. Therefore, some weird things might happen with GregTech's unification which will require you to edit GregTech's configs to fix the problem.

Natura
Natura is essentially incompatible with GregTech by default since Natura does not use the Ore Dictionary to register its wood logs. This might change in the future but as of now, you need to disable GregTech's wood nerf to get a consistent plank output for all types of wood. Saws will not work with Natura wood logs.

MineFactory Reloaded
MineFactory Reloaded was at some point re-registering every item as "greggy_greg_do_please_kindly_stuff_a_sock_in_it" in the Ore Dictionary when GregTech was detected. This has caused users of both MineFactory Reloaded and GregTech to complain about console spamming. Some users have also complained about automation breaking when both mods are installed. As a result, most of the code from the "greggy_greg" incident has been removed from the mod. However, MineFactory Reloaded still re-registers Leather Boots as "greggy_greg_do_please_kindly_stuff_a_sock_in_it" if GregTech is present.

In its current state, MineFactory Reloaded should be compatible with GregTech since it has a set of "harder" recipes for GregTech but this mod is labeled as incompatible since there is no guarantee something like the above won't happen again in the future.
