Hello everyone.
I was doing my daily research on some Sims 3 pages & I found this.

So... from now on there will be no more replacement meshes although there were some released before this.
It seems this tool makes it easier to do non replacement hair.
Before someone asks, this tool doesn't make meshes it's just to make the hair mesh non replacement.
