Virtually all simulation data, and some front-end data, is defined by a set of attributes created by the Attribute Editor. Mods can augment these attributes in one of two ways. Property bag group packs can override attribute data, replacing instances with entirely new ones that behave completely differently. Most other mods can add new attribute data, extending existing attribute data with new options.

Attribute Instance References

While attribute instances from the root data can be referred to by their name (their file name without the directory or extension), mod attribute instances must be referred to by their mod and name (<mod>:<name>).
