JEI UU Assembler
by Blue-Beaker
JEI UU Assembler lets Just Enough Items show the UU-Matter recipes of the IC2 Experimental UU Assembler and its related machines.
What it does
The mod works as an addon to JEI, adding recipe pages for the UU assembly bench, the Mass Fabricator and several IC2 machines. Each page lists the inputs and outputs of a recipe, so players can look up how UU-Matter machinery is used without leaving the game. Power and fluid machinery is covered too, with views for the generators, heaters and boilers that feed the UU chain.
The mod depends on MixinBooter, which must be installed alongside it on Forge 1.12.2. It works alongside Addon Enough Items IC2 and the IC2 Experimental Enough Items and Had Enough Items entries named by the author. Files are published for Forge only, for Minecraft 1.12.2, with 1.2.4 as the latest file, released on 2025-10-15. The client needs the mod to show recipes, while the server can run without it. The code is public, and the mod is released under All rights reserved, so it is not open source.
