Despite having UC and downloaded the Ultimate Soccer Kit from MATY, these clothes still won't show up with the proper meshes.

So does anyone know where the original Soccer Kit outfit meshes for CU/TU/AU are archived instead?

The only meshes in the "ultimate soccer kit" from MATY seem to be some toddler meshes, and by the looks of it the rest looks like face paint. It says on the MATY page that the older meshes/clothes were deleted from the package since they're included with FT.

If you have FT, can't tell you why they're not showing up. Probably something wrong in the 3DIRs. Likely an update or change between the soccer kit and FT.

The FT outfits are named "(gender/age)bodyworldcupep7" while the kit version is named like this "(Adult) (Male) Soccer (Red)" for the PropertySet, and I'm betting the mesh info is probably different, too, so the game likely considers them two different versions.

The meshes themselves are probably exactly the same, so it shouldn't be difficult to transfer the recolors from the ultimate set to the FT set using SimPE (extracting textures) and Bodyshop (recoloring FT outfits).
