The Cuisine module of the framework has one custom graphic class that can be used to provide custom graphics to items

• Graphic_RandomStackCount: New Graphic class that incorporates concepts from both Graphic_Random, and Graphic_StackCount, allowing for items to have both features.

How do I use this code?

It is Graphic class, so it can just be specified by placing it in the graphicClass tag of the Thing:

<graphicClass>VanillaCookingExpanded.Graphic_RandomStackCount</graphicClass>
