IDC Core allows for recipes to have multiple outputs. These outputs will automatically be displayed on the crafting UI to indicate to users what items a recipe will create.

Defining multiple outputs on a recipe is simple. An additional output on a recipe is defined as follows:

<secondary_output name="<item name>" count="<count>"/>

An example recipe is provided below:

		<recipe name="ammoArrowStone" count="1">
			<nameOverride name="customStoneArrowName"/>
			<iconOverride name="someCustomIcon"/>
			<descriptionOverride name="customRecipeDescription"/>
			<tintOverride name="FFFF00"/>
			<secondary_output name="ammoArrowIron" count="2"/>
			<secondary_output name="ammoArrowExploding" count="5"/>
			<ingredient name="resourceSmallStone" count="2"/>
			<ingredient name="resourceWood" count="1"/>
			<ingredient name="resourceFeather" count="1"/>
		</recipe>

The above example will produce 1 stone arrow, 2 iron arrows, and 5 exploding arrows when crafted. Recipes can have up to 5 total output items. Recipe names, descriptions, icons, and icon tints can be overridden as well. The name and description override values should be localization keys.

IDC Core automatically adds a tab to the crafting window to show what a recipe will create. This works with vanilla recipes and modded recipes.
