Cannot be 0.

Default: 0

Amount that should not be included in the consumption statistics, typically with a matching product having the same amount set as ignored_by_stats.

Lowest possible quality of ingredient that will be accepted. If not provided but quality_max is given, it will be set to the lowest quality from a quality chain to which quality_max belongs. When set, if the recipe would require ingredient from a different quality chain (due to quality of the recipe or quality roll), quality_min will be used for the quality instead.

Highest possible quality of ingredient that will be accepted. If not provided but quality_min is given, it will be set to the highest quality from a quality chain to which quality_min belongs. Must belong to the same quality chain as quality_min and be equal or better, meaning later in the chain when following QualityPrototype::next.

Default: 0

Amount of quality levels up or down this ingredient will be adjusted.

This is the difference between the quality of the recipe and the quality of the ingredient. For a vanilla example, when legendary is selected for recipe quality, an ingredient with quality change -1 would need to be epic quality, not legendary.

If quality_min is equal to quality_max, this is silently set to 0 as it does not make sense to define a quality jump when ingredient quality is fixed to one value for all qualities of recipe.

Default: 1

Controls how much spoil percent of this ingredient should influence spoil percent of spoilable products.

Must be in range [0, 1].
