The Lara Petite and and LaraX Petite come as an add-on for Maitreya mesh body and now also as a full body.
The Petite HUD and layers replace your Lara HUD and layers. The Petite (full body or add-on) come with a special Petite version of the Velour skins.
The Lara Petite and LaraX Petite (full body or add-on) have 3 nipple shape options: Regular, Hard and Puffy, just like the Lara mesh bodies. They also have the optional HD nipples, with 30 high resolution textures.
When you attach (wear) the Petite add-on it will hide and thereby replace the torso of your Lara mesh body. When the Petite add-on gets detached, your Lara torso becomes visible again. In the rare occasion that both the add-on and the body have been detached at once, it is possible that the next time you wear your mesh body, it still has the torso hidden. In that case you will need to briefly attach (and detach) the Petite add-on again, so that it can correct this.
BoM, appliers and alpha auto-hide will all work on your Petite (full body or add-on) as it does on your Lara body.
