    Tip: Double-click a tab to keep its parameters visible in the area. This lets you display the contents of several tabs at the same time.
    Substance Parameters Dedicated to material with Adobe substances.
    Reference Mapping Parameters Contains the mapping parameters for the material reference (that is, the material appearance). This mapping impacts all the material applications.
    Material application mapping Contains the mapping parameters for the applied material. This mapping is a local modification of the material appearance.
