A version of Spine/Skeleton shader that can be drawn within a Unity 2017 SpriteMask.
Shader "Spine/Skeleton SpriteMaskable" {

_Cutoff ("Shadow alpha cutoff", Range(0,1)) = 0.1
[NoScaleOffset] _MainTex ("Main Texture", 2D) = "black" {}
_StencilRef ("Stencil Reference", Float) = 1.0
_StencilComp ("Stencil Compare", Float) = 4.0 // For float values, see https://docs.unity3d.com/Manual/SL-Stencil.html under "Comparison Function" heading
}
SubShader {
Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
