Mod Compatibility (GregTech 5)/en

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

This article's main aim is to give somebody who does not like to mess around with things to get them to work a rough idea of what level of difficulty they should expect in attempting to get GregTech to work perfectly with their chosen mod.

Here are some general things you need to know about GregTech before we talk about mod compatibilities:
 * By default, GregTech only modifies Minecraft and IC2. However, GregTech makes use of the OreDictionary. Thus, some changes might have effects which seem weird to the user. For example, GregTech nerfs the default wood->plank->stick crafting, which might affect other mods that add different types of wood.

Do note that this does not apply to any mDiyo mods. The latter specifically requested that GregTech does not try to unify anything from his mods.
 * GregTech also unifies any materials it recognises into a single version of the material. For example, anything that is registered as ingotCopper is converted automatically to the IC2 version of Copper Ingots.

All Forge mods are somewhat compatible with each other due to the simple fact that they are using Forge. To avoid the use of the terms "compatible" and "incompatible" in this article, we shall define new compatibility levels as follows: Mods under this category should:
 * Level 1 Compatibility mods are basically mods that any GregTech user should consider adding to their mod list.
 * require no config editing to do at all. The mod should work with GregTech by default.
 * provide stuff that GT cannot not provide on its own.

Mods will fall under this category if: Straightforward config editing is for example, setting a value from true to false in a config. Anything more complicated than that will fall under the next category.
 * Level 2 Compatibility mods are mods that are still interesting to GregTech users but have minor issues.
 * They have issues that can easily be fixed with some straightforward config editing will fall under this category.
 * They have minor issues which can easily be worked around (if the issue cannot be fixed).

Mods will fall under this category if:
 * Level 3 Compatibility mods are mods that might be problematic for the average user.
 * They might cause unexpected problems.
 * The issue is quite severe and requires more work than straightforward config editing to get them to work with GregTech. For example, minetweaker or writing any sort of mod to fix problems.
 * They do not fall under previous categories.

This wiki will not document all Forge mods. Most Forge mods will at least be Level 2 Compatible. The few mods that are Level 3 Compatible are mods that either make a LOT of changes to Minecraft or are written by their authors so that they are not compatible with other mods.

Should you run into problems, remember that you can try asking for help on the forums or IRC channels.

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.

NEI
NEI is recommended by GregTech's mod author. NEI will show recipes for any item that uses the Crafting Table. NEI Plugins is an addon to NEI you might consider installing since it helps with recipes that do not use Vanilla Crafting Mechanics.

CodeChickenLib is installed automatically if NEI is installed.

Per Fabrica Ad Astra Geologica
, or PFAA, uses GregTech ore names if it detects that GregTech is present. Also, GregTech automatically 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.

Railcraft

 * is accepted by GregTech.
 * GregTech adds its own multiblock Boilers as from version 5.01i. These have their own mechanics and are different from Railcraft's . You might want to do some research before choosing which boiler better suits your needs.
 * Railcraft's 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  before going to the Nether; unless you manage to light a nether portal without flint and steel, or you find some steel in dungeon chests.
 * Sulfur, Tin, Copper, Iron, Gold and Saltpeter are all generated by GregTech.
 * If you choose to disable Railcraft's World Generation module, do note that GregTech will not generate Firestones.


 * Railcraft Firestone can be used to make meta-tools in GT. Any tool made out of Firestones will have the fire aspect III enchant and will autosmelt mined blocks.

Applied Energistics 2 (AE2)

 * AE2 Certus Quartz will not unify with GregTech Certus Quartz. That means AE2 Quartz will not magically transform into GT Quartz if you have World Generation from both mods enabled.


 * GregTech changes the AE2 Quartz -> Silicon smelting recipe. The only way to produce AE2 raw silicon is using the.


 * Note that you can obtain Charged Certus Quartz through GregTech Electrolyzers should you have AE2 World Generation disabled.

Thaumcraft 4 (TC4)

 * GregTech adds 5 new Compound Aspects to its own machines and tools in addition to existing TC4 Aspects.


 * You can disable TC4 Cinnabar Generation since GregTech generates those but it is best to leave all other TC4 World Generation with their default settings.


 * TC4 Thaumium can be used to make GT Tools. Thaumium tools will have fortune and looting II.
 * TC4 Shards can be used to make GT tools with low durability, but special properties.

BiblioCraft
Bibliocraft has support for GregTech Tools as of Bibliocraft version 1.7.3 (for Minecraft 1.7.10).

Forestry
Forestry should work without problems by default but disabling Apatite Generation from either Forestry or GT might lead to problems.

Pam's HarvestCraft
Many of the foods that are added by GregTech are only available if HarvestCraft is installed. This is because of all of the new crops that it adds.

Thermal Expansion
Thermal Expansion's Fluid Transposer will not fill water bottles. A work around is to use Autonomous Activators instead.

Tinkers' Construct (TiC)
would have been a Level 2 Compatibility Mod with GregTech, except for one problem : TiC Aluminum is unified into GT Aluminium which is unusable in TiC Smelteries.

The reason for this is that TiC accepts only Aluminum in its Smelteries but GT names its Aluminium Aluminium, which is the preferred IUPAC name.

Possible solutions include:
 * Editing GregTech's unification configs.
 * Writing a mini-mod to re-register GT Aluminium Ingots under ingotAluminum in the OreDictionary.

Be warned that other problems might appear as you use both Mods together.

Natura
is incompatible with many mods by default since Natura does not use the OreDictionary to register its wood logs. This might change in future versions but as of now, GregTech's wood nerf will not reduce the plank output of Natura logs, resulting in inconsistent plank output between Natura trees vs. OreDictionary trees. Furthermore,, the and the  will not work with Natura wood logs.

Possible solutions include:
 * Disabling generation of Natura trees in Natura's config
 * Disabling GregTech's wood nerf, so that all trees produce the same number of planks (i.e. 1 log --> 4 planks, without a Saw)

There is currently no way for other mod authors to fix this problem since the Natura author refuses to allow others "mess with his stuff".

MineFactory Reloaded (MFR)
in the past re-registered 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 not working as expected when both mods are installed. As a result, most of the code from the "greggy_greg" incident has been removed from the mod. However, MFR still re-registers Leather Boots as "greggy_greg_do_please_kindly_stuff_a_sock_in_it" if GregTech is present.

Currently, MFR can be considered to be a Level 2 Compatibility mod with GregTech but be aware that you might run into unknown/unexpected problems.

Optifine
Optifine might or might not work depending on your setup.

TerraFirmaCraft (TFC)
While it is not known whether TFC is actually compatible with GregTech, the latter has support for all of TFC's alloys and metals.

Do note that it is possible to produce some of TFC alloys without the mod itself and use them as materials for meta-tools, most notably the various types of steel. These have varying levels of the sharpness enchant depending on their complexity.

Flaxbeard's Steam Power (FSP)
Flaxbeard's Steam Power's Plates are not compatible with any other mod's plates, due to their OreDict entry "steamcraftPlate". This is intentional, and will not be changed, as FSP plates are made out of 6 nuggets, while the convention is 1-2 ingots.

There isn't really a solution, it's more something that users will simply need to leave with and work around by having different plate-creation systems for the different mods.
