Unity 打包安卓没有阴影

查看shader的状态

直接复制这段，导报到手机上是有会问题的

一些状态啊什么的会出问题

  Pass
{
    Name "ShadowCaster"
    Tags{"LightMode" = "ShadowCaster"}

    ZWrite On
    ZTest LEqual
    ColorMask 0
    Cull[_Cull]

    HLSLPROGRAM
    #pragma only_renderers gles gles3 glcore d3d11
    #pragma target 2.0

    //--------------------------------------
    // GPU Instancing
    #pragma multi_compile_instancing

    // -------------------------------------
    // Material Keywords
    #pragma shader_feature_local_fragment _ALPHATEST_ON
    #pragma shader_feature_local_fragment _SMOOTHNESS_TEXTURE_ALBEDO_CHANNEL_A

    #pragma vertex ShadowPassVertex
    #pragma fragment ShadowPassFragment

    #include "Packages/com.unity.render-pipelines.universal/Shaders/LitInput.hlsl"
    #include "Packages/com.unity.render-pipelines.universal/Shaders/ShadowCasterPass.hlsl"
    ENDHLSL
}

可以替换成下面的代码

Pass
{
    Name "ShadowCaster"
    Tags{"LightMode" = "ShadowCaster"}

    HLSLPROGRAM
    #pragma prefer_hlslcc gles
    #pragma exclude_renderers d3d11_9x
    #pragma target 2.0

    #pragma vertex ShadowPassVertex
    #pragma fragment ShadowPassFragment

    #include "./LitInputSSS.hlsl"
    #include "Packages/com.unity.render-pipelines.universal/Shaders/ShadowCasterPass.hlsl"
    ENDHLSL
}
