解决

1.创建urp资产

创建成功如下图

2.打开Edit > Project Settings… > Graphics

3.设置资产

如果你安装了URP包，当你编写自定义渲染管线时，既是你设置的上图资产也会报同样的错误。

解决办法是卸载URP包。安装自定义可编程渲染管线基础包。Url为 com.unity.render-pipelines.core。复制url到packageManager里面添加基础包。

点击add package from git url ,输入url为com.unity.render-pipelines.core ，然后add 可编程渲染管线报错 Unity Universal RP asset not assigned,U3D,U3D shader编程,unity,游戏引擎

安装完成如下

后面就可以编写自定义渲染管线了

渲染管线资产

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;
using UnityEngine.Rendering;
[CreateAssetMenu(menuName = "Rendering/MyPipeLineAsset")]
public class MyPipeLineAsset : RenderPipelineAsset
{
    
    protected override RenderPipeline CreatePipeline()
    {
        return new MyRenderPipeLine();
    }
}

渲染脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Rendering;

public class CameraRender
{
    private ScriptableRenderContext context;
    private Camera _camera;

    public void Render(ScriptableRenderContext context, Camera camera)
    {
        this.context = context;
        this._camera = camera;
        Draw();
    }

    private void Draw()
    {
        // 创建并调度命令以清除当前渲染目标
        var cmd = new CommandBuffer();
        cmd.ClearRenderTarget(true, true, Color.black);
        context.ExecuteCommandBuffer(cmd);
        cmd.Release();
        DrawSky();
        CameraCull();
        Submit();
    }

    private void DrawSky()
    {
        context.SetupCameraProperties(_camera);
        context.DrawSkybox(_camera);
    }

    private void CameraCull()
    {
        _camera.TryGetCullingParameters(out var parameters);
        var result = context.Cull(ref parameters);

        DrawingSettings drawingSettings = new DrawingSettings();
        drawingSettings.SetShaderPassName(1, new ShaderTagId("SRPDefaultUnlit"));
        SortingSettings sortingSettings = new SortingSettings();
        sortingSettings.criteria = SortingCriteria.CommonOpaque;
        drawingSettings.sortingSettings = sortingSettings;
        FilteringSettings filteringSettings = new FilteringSettings(RenderQueueRange.opaque);
        context.DrawRenderers(result, ref drawingSettings, ref filteringSettings);


        sortingSettings.criteria = SortingCriteria.CommonTransparent;
        filteringSettings.renderQueueRange = RenderQueueRange.transparent;
        context.DrawRenderers(result, ref drawingSettings, ref filteringSettings);
    }

    private void Submit()
    {
        context.Submit();
    }
}

public class MyRenderPipeLine : RenderPipeline
{
    private CameraRender _cameraRender = new CameraRender();

    protected override void Render(ScriptableRenderContext context, Camera[] cameras)
    {
        foreach (var camera in cameras)
        {
            _cameraRender.Render(context, camera);
        }
    }
}
