At the moment this is a fairly raw dump of the metaped assets, more context on their use is provided by t3chman here: https://forum.cfx.re/t/ped-modification-and-metadata-overview-outfits-assets-expressions-shop-items-overlays-etc/5124046
I have extracted the metaped assets and run a tool to categorize the associated albedo, normal, material from the matchtag references and then output lua compatible tables with the data.
