Unity3d Research institute The local transparency effect when the camera and the role are blocked

1. The local transparency effect is achieved by shader modification

Shader "Custom/playerdiffuse"
{
Properties
{
_notvisiblecolor ("Notvisiblecolor (RGB)", Color) = (0.3, 0.3, 0.3, 1)
_maintex ("Base (RGB)", 2D) = "White" {}
}

Subshader
{
Tags {"Queue" = "geometry+500" "rendertype" = "Opaque"}
LOD 200

}

}

SetTexture [_maintex] {combine texture}
}

}
FallBack "Diffuse"
}
