GT Community Additions
by mordgren
GT Community Additions brings GregTech multiblocks, materials and machines from the community to a Forge 1.20.1 instance.
What it does
The mod adds community-made GregTech content on top of the GregTech Modern base. Its additions include a set of multiblocks and materials, and several machines originally written for the GregTech family, such as the Steam Pressurizer, Chemical Combustion Engines, Polymerizer and the Extreme Heat Exchanger. Advanced EBF is a reworked version of an earlier GT++ design.
GT Community Additions requires GTCEu Modern 7.2.0 or newer on Forge 1.20.1, with later builds targeting the 7.0.0 line. Some of its recipes depend on the Green House, which must be present for those recipes to load. GT-- is an optional dependency; without it a few recipes are missing.
The mod is open source under the GNU Lesser General Public License v3.0 or later. Client and server both need it, so every player on a server running it must install the mod as well. Files exist only for Forge 1.20.1, with the latest build 2.2.0 published on 2026-08-24.

How it compares
Gregtech Terminals is a Forge 1.20.1 add-on that is open source under the MIT License and runs on client and server, covering terminal interfaces rather than multiblocks. GregTech Modern Quality of Life is a Forge 1.20.1 mod under the GNU Lesser General Public License v3.0 only and is client-side only, so servers need nothing from it. CM:ME Additions is not open source, uses the Creative Commons Attribution Non Commercial Share Alike 4.0 license and also runs on client and server.
