Hey simplesim7!
This is the only way that I think to talk directly to you.
I'm beginning to learn how to mod some features of Haydee, but I'm stuck on change her model and such mesh things. I need a veteran like you to point what I need to do.
I just can't import new .skel neither skins. We can talk at any time through this group if you can, of course.
I need your help.
