I wasn't sure where to ask this since I can't find a discord (if one exists?) but I'm trying to make custom recipes for the Altars, but I want to leave spaces empty between some ingredients... but I'm not sure how to do that. I've tried using minecraft:air, but that doesn't seem to work. So I'm wondering is it possible to leave slots empty similar to how the infusion recipes in BetterEnd work. I'm on 1.20.1 if that matters!

The altars use the same ingredient input logic of shapeless crafting recipes, which doesn't allow adding empty items.

I think what I'll do is make it so the inputs are placed nicer for recipes with less than 8 inputs in the JEI category since that's realistically the only situation where this matters.

I'll note I'm only making this change for Infusion recipes as Awakening recipes while technically shapeless are very intentionally meant to be 4 essences + 4 items.

Ahh I see, I just wanted to be sure I wasn't missing an obvious way to do it lol. I'll just add some filler ingredients in between then thank you :)!
