It’s good that it displays in the crafting table that certain parts are disabled which is a bit lackluster (Modpack maker can’t even set a custom message why they are disabled to display).

There is no message for disabled casting either so people mostly just wonder why the material wont pour out into the cast.

Having the disabled parts not be visible in Mods like JEI would be a great help. Thought I would like the custom messages as well.

Is this possible?

The messages i can fix/add. But the jei hidding you can do that through jei itself.
