将 PostProcessEffectRenderer 的实现添加到 Unity 后处理堆栈后，效果在 Unity 编辑器中完美运行，但不会在构建的游戏中显示。

对构建质量的更改无效，使用最高质量设置时不会显示效果，为 Windows x86_64 构建。

using System;
using UnityEngine;
using UnityEngine.Rendering.PostProcessing;

[Serializable]
[PostProcess(typeof(GrayscaleRenderer), PostProcessEvent.AfterStack, "Custom/Grayscale")]
public sealed class Grayscale : PostProcessEffectSettings
{
    [Range(0f, 1f), Tooltip("Grayscale effect intensity.")]
    public FloatParameter blend = new FloatParameter { value = 0.5f };
}

public sealed class GrayscaleRenderer : PostProcessEffectRenderer<Grayscale>
{
    public override void Render(PostProcessRenderContext context)
    {
        var sheet = context.propertySheets.Get(Shader.Find("Hidden/Custom/Grayscale"));
        sheet.properties.SetFloat("_Blend", settings.blend);
        context.command.BlitFullscreenTriangle(context.source, context.destination, sheet, 0);
    }
}
