Body HUD Appearance
This somewhat daunting section of the HUD is for managing your appearance - how your body looks not the shape. There are four sections to this page of the HUD:
Visibility - Manage visibility of some areas of the body that commonly need it
Skin - Apply materials, erase, restore to BOM
Applier Layer - Configure how appliers will affect the one applier layer on the regular body (LITE has no applier layer)
Materials - Customize the materials for your body
Visibility
This small section of the HUD is used to hide or show some very specific portions of your body that are commonly needed. For example, you're wearing boots that fully cover your feet or maybe they stick out a bit - hide them :) Want more privacy? Hide your nipples or groin.
