You are going to need the mesh file for these hairs to show up in your game. The mesh can be found here:
peggysims donation mesh#0028 located on pg14 in the donation hair mesh section.
Peggy Sims 2 I would direct link for you but Peggy does not allow for direct linking in the donation area.
Here is a photo of the whole set.
The whole set of Peggy’s can be found on page 100 of the female hair section in the donation area. This set includes the mesh.'
The mesh isn't included in the recolour set.
Did you look for the mesh @ Peggyzone? I'm looking now so I'll post the link here.
