Immersive Engineering Mod (1.16.5, 1.18.2) adds new Redstone Flux-based machinery to the game. Many of the machines have a multiblock structure. Machines can use low, medium, or high voltages, with 256 RF/t representing low, 1024RF/t representing medium, and 4096RF/t representing high.
Multiblock machines are its most well-known feature. They have an industrial appearance. Single and multiblock machines can operate at three power levels: low voltage is 256 RF/t; medium is 1024 RF/t; high corresponds to 4096 RF/t.
It can also be used with EU Energy IndustrialCraft 2.
Engineer’s Manual is the most important tool in this mod. It was created by combining a book with a lever. It includes instructions and recipes for every mod.
