AU: Immersive Engineering in All the Mods 10: To the Sky

AU: Immersive Engineering is a small add-on that connects Almost Unified with Immersive Engineering. You won't craft anything with it or see new blocks. It works in the background to keep the pack's recipes and resource outputs consistent.^[1]

Immersive Engineering's authors were asked about building this integration directly into their mod and declined. It used to be part of the base Almost Unified mod, but growing compatibility issues meant a separate add-on was the only option. This add-on is that add-on.^[1]

What it does

• General recipe unification: it converts the recipes of all Immersive Engineering recipe types.^[1]
• Arc Furnace recycling unification: the recycling outputs follow the same unified choices.^[1]
• Mineral Deposit unification: ore deposits use the unified output as well.^[1]

The add-on also intercepts Immersive Engineering's internal priority logic, so mechanics that rely on it, such as ore deposits and Arc Furnace recycling, give the appropriate output. While it is installed, the priorities in Immersive Engineering's own config only apply to items that Almost Unified doesn't already handle.^[1]

Who it's for and where it fits

This one is for anyone using Immersive Engineering machines in the pack who wonders why they get the same ore or metal variants everywhere. You don't need to configure anything to benefit. The pack includes version 1.21.1-1.0.1 of the add-on.^[1][2]

Unverified The sources don't place this mod on the ATM Star path, and no quests in the pack are tied to it. Treat it as a background compatibility tool rather than a progression step.

Here's the thing to know before you start: AU: Immersive Engineering is not a mod that adds items for you to craft. It's an Almost Unified integration for Immersive Engineering, so there's no first item to make from this mod and no recipe for me to point you to.^[1]

The add-on exists because the Immersive Engineering authors were asked about direct integration with Almost Unified and declined. An add-on was the only way to keep the integration working.^[1]

What it does for you

• General recipe unification: it converts the recipes of all Immersive Engineering recipe types.^[1]
• Arc Furnace recycling unification: recycling results follow the same unified outputs.^[1]
• Mineral deposit unification: ore deposits use the appropriate unified output.^[1]

Your first steps

You don't need to do anything special to turn this on. It works in the background, so the best way to start is with Immersive Engineering itself and its own recipes.^[1]

Unverified I can't confirm a recommended order of first items to craft in this pack. No quests, in-pack recipes or guidebook entries for this mod were available, so I'm not listing a progression here.

This mod isn't a machine mod. It's a bridge: it adds Almost Unified integration to Immersive Engineering. The integration used to be part of the base Almost Unified mod. With the growing number of compatibility issues, the Immersive Engineering authors were asked about integrating it directly and declined, so an add-on was the only way to keep it working.^[1]

What the add-on handles

The add-on holds the recipe unifier for all Immersive Engineering recipe types, and it uses that unifier to convert their recipes. It also lets Almost Unified convert the internal priority system Immersive Engineering uses, not just its recipes.^[1]

The add-on intercepts that priority logic, so every mechanic relying on it uses the appropriate output. Ore deposits and Arc Furnace recycling are the examples the project page gives. Its feature list is short:^[1]

• General recipe unification across Immersive Engineering's recipe types.^[1]
• Arc Furnace recycling unification.^[1]
• Mineral Deposit unification.^[1]

How priorities work with this add-on

Immersive Engineering has its own priority settings in its config. While this add-on is installed, those settings are only used for items that Almost Unified isn't already handling. If Almost Unified already handles an item, its choice wins.^[1]

Unverified How Immersive Engineering's machines, multiblocks, power, fluids and automation work is not shown in the sources here. No in-jar guidebook was found for this add-on and the pack has no config files for it, so those details are left out rather than guessed.

This add-on has a short history. All the Mods 10: To the Sky 2.0.4 ships AU: Immersive Engineering 1.21.1-1.0.1, and the mod has been in the pack since version 1.0 or earlier.^[2]

Mod releases

• 1.21.1-1.0.0: the initial 1.21.1 release.^[3]
• 1.21.1-1.0.1: fixed the preferred stack API selection logic for multi stack input.^[4]
• 1.21.1-1.0.1: fixed an issue where all stacks ended up with a count of 1 when they were replaced via the API.^[4]

Both of those fixes are already in the version you get in 2.0.4, so you don't need to do anything to benefit from them.^[2][4]
