//
// OvrAvatar PC single component shader
//
// This is a Unity Surface shader implementation for our 1.5 skin shaded avatar look.
// The benefit of using this version is that it uses the full Unity PBR lighting under the hood.
// The Mobile shader is strongly recommended for use on mobile platforms for performance.
//
// Notes:
// - Use Mobile shader if you need mouth vertex movement.
