[unity URP] the code obtains the universalrendererdata of the current URP configuration and dynamically adds the rendererfeature

Reference resources https://forum.unity.com/threads/how-to-access-scriptablerendererdata-from-script.1012336/

Code to get the current UniversalRendererData

We go through GraphicsSettings.renderPipelineAsset or QualitySettings.renderPipeline, Can be obtained Edit in Graphic or Quality Set in the URP To configure .

But we can't get RendererList,

UniversalRenderPipelineAsset This attribute is not opened .

So we can get this property through reflection .( Got RendererList First of all data)

        UniversalRenderPipelineAsset URPAsset = (UniversalRenderPipelineAsset)QualitySettings.renderPipeline;
        FieldInfo propertyInfo = URPAsset.GetType().GetField("m_RendererDataList", BindingFlags.Instance | BindingFlags.NonPublic);
        UniversalRendererData URPData = (UniversalRendererData)(((ScriptableRendererData[])propertyInfo?.GetValue(URPAsset))?[0]);

Dynamic addition RendererFeature Rendering

Code completion AddRendererFeature function （ Available at run time ）

Take rendering in the front as an example ：

        RenderObjects rendererFeatrue = ScriptableObject.CreateInstance<RenderObjects>();
        rendererFeatrue.name = "Test";
        // Fill in the desired layer
        rendererFeatrue.settings.filterSettings.LayerMask = (1 << LayerMask.NameToLayer("yourlayer0") | 1 << LayerMask.NameToLayer("yourlayer1"));
        // Set whether the material is transparent 
        rendererFeatrue.settings.filterSettings.RenderQueueType = RenderQueueType.Transparent;
        rendererFeatrue.settings.overrideDepthState = true;
        rendererFeatrue.settings.depthCompareFunction = CompareFunction.Disabled;

After creation , Add to UniversalRendererData Of rendererFeatures in

URPData.rendererFeatures.Add(rendererFeatrue);

Finally , Make it effective immediately .

URPData.SetDirty();

it is to be noted that , If in Editor Next play, After closing, in URP In profile , Dynamically added Reature It'll be empty , So we need to OnDestory Clean up in .

Complete code ：

 private RenderObjects rendererFeatrue;
    private UniversalRendererData URPData;
    private void Start()
    {
        AddRenderFeatrue();
    }

    private void OnDestroy()
    {
        URPData.rendererFeatures.Remove(rendererFeatrue);
    }

    private void AddRenderFeatrue()
    {
        rendererFeatrue = ScriptableObject.CreateInstance<RenderObjects>();
        rendererFeatrue.name = "Test";
        rendererFeatrue.settings.filterSettings.LayerMask = (1 << LayerMask.NameToLayer("yourlayer0") | 1 << LayerMask.NameToLayer("yourlayer1"));
        rendererFeatrue.settings.filterSettings.RenderQueueType = RenderQueueType.Transparent;
        rendererFeatrue.settings.overrideDepthState = true;
        rendererFeatrue.settings.depthCompareFunction = CompareFunction.Disabled;

         
        UniversalRenderPipelineAsset URPAsset = (UniversalRenderPipelineAsset)QualitySettings.renderPipeline;
        FieldInfo propertyInfo = URPAsset.GetType().GetField("m_RendererDataList", BindingFlags.Instance | BindingFlags.NonPublic);
        URPData = (UniversalRendererData)(((ScriptableRendererData[])propertyInfo?.GetValue(URPAsset))?[0]);
        URPData.rendererFeatures.Add(rendererFeatrue);
        URPData.SetDirty();

    }
