I have enabled the mod setting “Show flux/coherence recipes in Factoriopedia”. This works in that voidcrafting recipes like “Electric mining drill + flux” are listed in Factoriopedia in the “+ Void flux” category. However, Factoriopedia doesn't show which technology is required to research this recipe. The slower voidcrafting recipes like “Electric mining drill” do show the tech requirement, in this case “Large-scale voidcrafting”. I think the tech requirement should be shown for every recipe.

There is no technology for void flux variants, just like there is none for the coherence infusion variants.

They are unlocked automatically via script when you research their regular void-craft variant.

Thank you, I understand. I still think it would be cleaner if that same technology was shown for the fluxcrafting recipe as well.
