Description from the author on Modrinth

3C is a small, carefully curated NeoForge pack built around one loop: Create gives you the moving parts, CC: Tweaked gives you the brain, and CC:C Bridge wires them together.

No quest book, no kitchen sink. Twenty mods, one idea, and enough headroom left for your render distance.

What's inside

The core trio

  • Create - kinetic power, cogs, deployers, trains, and the mechanical bits everything else hangs off
  • CC: Tweaked - in-world computers, turtles, and Lua scripting
  • CC:C Bridge - exposes Create's block peripherals to ComputerCraft, so your factory can be software

Performance
Sodium, Iris Shaders, Distant Horizons, ImmediatelyFast, Entity Culling, ModernFix, and FerriteCore. The pack is designed to stay playable with absurd render distances and shaders on at the same time.

Quality of life
JEI for recipe lookups, Jade for block info, AppleSkin for hunger readouts, Mouse Tweaks, and CreativeCore as a dependency.

Immersion
AmbientSounds, Presence Footsteps, and Sound Physics Remastered. Optional in spirit, but hard to go back from.

Who this is for

  • You write code for a living and want to write code for fun
  • You want a server pack with a defined tech identity, not an everything pack

Requirements

  • Minecraft 1.21.1
  • NeoForge
  • Java 21+
  • RAM 4 GB minimum, 6 GB recommended (8 GB if you run Distant Horizons with a large LOD radius)

Runs on client and server. Everything is required on both sides; there are no client-only shortcuts here.

Known issues

  • Shader users: test Distant Horizons and Iris together on your hardware before committing to a world. Results vary wildly by GPU.

How to install 3C: Cogs, Code & Contraptions

  1. This modpack runs on NeoForge for Minecraft 1.21. The launcher you install it with sets that up for you.

  2. Download the .mrpack file from Modrinth.

  3. Open it with a launcher that reads .mrpack files, such as the Modrinth App or Prism Launcher: it makes a new instance with every mod and setting of the pack.

  4. Give the instance enough memory: most modpacks want 4 to 8 GB.

  5. To play it with friends on a server, use the server files of the modpack if its page offers them; otherwise install the same mods on the server.
