Topic category: Feature requests and ideas for MCreator
Currently, the few ways of making recipes for custom GUIs involves either manually assembling each recipe inside of a procedure, or using Just Enough Recipes (As far as I'm aware), neither of which show the recipes in the vanilla recipe book, and neither of which let you create data driven recipes through JSON.
I think an element to create custom Recipe Types would be extremely useful, as well as a way to tie them to GUIs, and show recipe books pointing to them inside of GUIs. Once a recipe type is created, it could be available both in the "Recipe type" dropdown in the existing Recipe element, and would also be available for use in recipe JSON files.
I'm aware this suggestion has been made a few times in the past, but all of the examples I could find either received little to no reception, or are multiple years old, and I'd like to bring the idea up again.
