For example the researcher doesn't accept Immersive Engineering Bauxite (which is what we unified our oregen around), because the input isn't oredicted.

the researcher is oredict compatible (tested woth our own server with copper from different mods). As far as I know we did not register our bauxit to avoid unbalancing IC². But I dont know exactly.

We use "oreBauxite" and Immersive Engineering "oreAluminum". We think Bauxite is the more correctly solution. Specially because we don't like to have direkt smelt recipies.

In terms of your problem, we added "oreAluminum" as an alternative for the Research. But note that this don't make the ores compatible*, you only get the chanche to unlock all content, without having Bauxite from our mod. (in other words you don't need our ore)

*If you necessarily need full compatibility, try to ask Immersive Engineering to change/add the OreDict name ("oreBauxite").
