Custom Crafting Recipes

Vanilla crafting recipes can be gated! Well, visually, at least. Everyone knowing the exact ingredients will always be able to craft them, but recipe viewers show them as gated.

General Properties

Entry	Type	Default	Description
group	string	empty	A string that represents a recipe group. Recipes with a common group will only trigger a single unlock popup, if multiple are unlocked at once. Add a localization string "recipeGroup.spectrum.<<your_group_string>>" so the toast popup is properly localized
required_advancement	advancement_identifier	empty	The advancement a player needs to have to be able to see this recipe. Spectrum will automatically show a recipe unlock toast when this advancement has been gotten and the Pedestal has the correct tier
reveal_secret_advancement	advancement_identifier	empty	If set, the recipe shows up as a secret in recipe viewers at first, until the player has the set advancement. You can set a hint by adding a lang key recipe.spectrum.<recipe_type_id>.secret.<recipe_id>.hint
additional_recipe_viewer_results	itemstack list	empty	Items that will be considered an "output" of the recipe for recipe viewers when pressing "R". Has no gameplay relevance, but is a nice QoL thing for your players, if your recipe does something funky.
result	item_stack		Output item stack, supports NBT
