There's a cool new Datapack in town!
"Engineered Compatability" ties Immersive Engineering in with a bunch of other mods (and some vanilla recipes too!)

This is developed by Voidsong, who has contributed a bunch of content to IE recently and she has now made this datapack of things that don't belong in core IE, but are still super useful to have!

Engineered Compatibility - Minecraft Mod

Engineered Compatibility is a datapack-mod that adds compatibility to Immersive Engineering for a host of other mods.

I know I have basically zero reach on here, but I'd be doing a disservice if I didn't promote it outside of twitter as well.

Also, for those that prefer the convenience of CurseForge, here's a link for that:

(Use Modrinth if you can though, it's better.)
