Frequently asked questions (FAQ)

Releases

Which Minecraft versions are supported?

See the Mods page for the latest supported Minecraft version. Older versions get no new content or bug fixes.

Is there an ETA for X?

No. Things come out as they are ready. Please be patient and understanding.

Will you make Fabric, Quilt or Bedrock versions?

No. We have no plans to put our mods on Fabric, Quilt or Bedrock. If you want to play Fabric mods alongside ours, Sinytra Connector runs many of them on Forge and NeoForge.

Can I port a CoFH mod to another loader?

No. CoFH mods cannot be ported to other loaders. This includes Thaumcraft.

What are the plans for Thaumcraft?

It is being worked on; there is no ETA and there are no early builds. Join our Discord for teasers and development updates.

Using the mods

Can I use your mods in my modpack?

Yes.

Where are the configs?

Some configs are in the normal config folder; others are in the serverconfig folder inside your world folder. To apply those to every new world, copy the changed files into the defaultconfigs folder.

Where are the docs for newer versions?

They are being worked on. Until then, use the Thermalpedia (Patchouli) and JEI. The existing Minecraft 1.12 docs will remain available.

How do I add recipes with KubeJS or CraftTweaker?

Ask on their Discord servers: you will get faster and better help there. We are happy to help with data packs.

Which mods are known to cause problems?

OptiFine crashes the game. Remove it.

Where can I get help, report bugs or suggest things?

On Discord: #bug-reports for bugs, #suggestions for ideas and #tech-support for help.

Thermal Series

My game asks for “thermal”. Which mod is that?

That is Thermal Foundation. It’s required when installing any other mod in the Thermal Series.

Where are the tools made from Thermal metals?

They moved to Tool’s Complement. It doesn’t need Thermal: tools appear for any mod that adds the metals.

Where are tiered ducts, itemducts and covers?

Tiered ducts are gone: ducts move plenty without upgrades. Itemducts will return later. Duct covers are not planned for now.

Why is my dynamo slowly losing power?

A dynamo’s energy buffer is only a throttle; dynamos are not meant to store energy. Use a Redstone Flux Cell for that.

Can you make mod X work with Thermal machines?

Sure, as long as it doesn’t break the other mod or conflict with Thermal. Post it in #suggestions on Discord.

How do I change ore generation in the newer versions?

There is a config to turn the ores on or off. To change sizes, counts and heights, use a data pack that overrides data/thermal/worldgen/placed_feature. Copy those files from the Thermal Foundation jar or its GitHub repository and change size, count, min_inclusive or max_inclusive. You can use Open Loader to apply the data pack to every new world.

Is the Blitz being removed now that the Breeze exists?

No. The Breeze is air; the Blitz is lightning.

Units and terms

What is Redstone Flux (RF)?

The energy system of Team CoFH’s mods. It is the same as Forge Energy (FE), so Thermal machines work with any mod that uses it.

See Redstone Flux: A Primer for an in-universe explanation.

What is the history of Redstone Flux?

Thermal Expansion originally ran on BuildCraft’s Minecraft Joules (MJ). As MJ’s API grew increasingly complex and opinionated, Thermal Expansion 3 for Minecraft 1.6 replaced it with Redstone Flux. RF was simpler and lossless, and any mod could include it without depending on Thermal Expansion.

Many other mods quickly adopted Redstone Flux. Eventually, Forge based its own energy system, Forge Energy, on it. Our mods switched to Forge Energy too, but still call it RF.

What is a millibucket (mB)?

The unit for amounts of fluid: one bucket holds 1,000 mB. It is the unit of the fluid system in Forge and NeoForge, which lets mods move and store fluids in amounts smaller than a bucket.

What do RF/t and mB/t mean?

RF or mB per tick (1/20 of a second): the rate at which energy or fluid is moved, produced or used.

What is the difference between RF and RF/t?

RF is an amount of energy; RF/t is a rate, also called power. A job takes a fixed amount of energy, and the machine’s power decides how long it takes. For example, a Pulverizer spends 4,000 RF per ore. At 20 RF/t that takes 200 ticks (10 seconds), and upgrading its maximum power usage shortens that time.

Team CoFH

What does CoFH stand for?

Cult of the Full Hub: the name of King Lemming and Cynycal’s LAN gaming group in the late ’90s, also known as a hub. Its goal was to fill the hub to its cap of 8 people, and eventually it did so routinely.

What are the origins of Team CoFH?

In 2012, King Lemming and Cynycal teamed up as Team CoFH to make Minecraft mods. It was mostly a way for King Lemming to learn Java. They started on Brewcraft, a farming mod with a brewing overhaul.

Soon after, King Lemming began experimenting with a furnace that ran on BuildCraft’s Minecraft Joules. More blocks like it followed, and together they became the first version of Thermal Expansion, for Minecraft 1.2. Brewcraft was left behind.

Since then, Thermal Expansion grew and eventually split up into the Thermal Series. One of its mods, Thermal Cultivation, is a farming mod, bringing things full circle.

Who is part of Team CoFH today?

It changes over time, as people join, move on or help with a single mod. King Lemming still leads development. You can find the current team on GitHub and on Discord.

How can I support the team?

Become a monthly member on King Lemming’s Ko-fi or Reda’s Ko-fi, or boost the Discord server. Nice words go a long way too!
