Hair referencing two textures?

[Layana]

The hair "Ponypuff" (from TSS) has different color hair bands on each color texture of the hair. For instance, blond has the green hair band, and black has the purple hair band.
Apartment life introduced this hair for Young Adult, Adult, and Elder, making each color hair have every color hair band. To do this, they used two textures. Example: to get blond hair with purple hair band, they used the blond texture for the blond hair, and the black texture for the purple hair band.

I would like to do the same for the Teen age (and other ages using melodie9's meshes) so I can have every color hair with every color hair band. I just have no idea how to implement that second texture.
I've tried exporting the adult hair, and changing the mesh linked to it along with the age in the Property Set. When I do that, the hair pulls the blond texture just fine, but the hair band is still green instead of purple.

So, how do I make that second texture work? Any help is appreciated, and if I didn't explain myself well enough please let me know.

You'll have to look at what parts the original mesh has for guidance. There's probably like... hair, hairalpha3, hairalpha5, and hairband. You'll need to set up your mesh in a similar way, and for the material definition for the hairband group, set it to the same as the original Maxis textures are using. You can do this for the other groups too - not have any textures included, just material definitions, and save quite a lot on file size.

Oh, so it involves modifying the Mesh package? Unfortunately that is beyond my abilities at the moment, thank you for the information.

Well, the mesh needs to be set up properly to do so... You'll have to have the hairband as a different part from the hair in order to reference it separately in the recolours. It's mainly a material definition thing, but unless you've got separate parts for the hair and hairband, it won't work.

You had said "There's probably like... hair, hairalpha3, hairalpha5, and hairband." Well, to clear that up, for Adult hair it's simply hair and tie.

I found your tutorial How to add new groups to a Mesh (http://www.modthesims2.com/showthread.php?goto=newpost&t=213184). Is this what I need? I tried to follow it, but ("Edit the mesh in Milkshape, giving it the amount of groups you need.") I don't have Milkshape.

So, I'm trying to say I don't understand how to change the mesh, can it be done with just SimPE, or is Milkshape necessary?
