I use UIPanel and under this panel , I use a sprite with a simple custom stencil shader
Shader "Custom/HIdden" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
Tags { "RenderType"="Opaque" }
LOD 200
Stencil
{
Ref 1
Comp Equal
}
CGPROGRAM
#pragma surface surf Lambert
sampler2D _MainTex;
struct Input {
float2 uv_MainTex;
};
void surf (Input IN, inout SurfaceOutput o) {
half4 c = tex2D (_MainTex, IN.uv_MainTex);
o.Albedo = c.rgb;
o.Alpha = c.a;
}
ENDCG
}
FallBack "Diffuse"
}
as the code , the sprite will hidden unless set the stencil buffer , but if i set the panel to soft clip , The sprite shows all the time .Is anyone can point out why the stencil shader not work ? thanks !!
