Overview

Research by Tiger - work in progress

Parts of the data contained in this resource follows the format of Sims_3:Catalog_Resource#Material_List and Sims_3:0xCF84EC98. The lot objects section references resources indexed by Sims_3:0x05ED1226.

This is a very rough draft, there are some key pieces of information missing.

    WORD residx ? (Seems like it's always 0:0:0)
    WORD residx VPXY
    [Component specific data]

The component specific data depends on what components are listed. The order is fixed, and completely unrelated to the order the components are listed in. Each section appears in the order here, only if the named component is included. This order is inferred by comparing different selections of components from different resources. In some places the order may not be exact when the components in neighboring locations never appear together, such as "Tree", "Effect" and "Steering".
