EnquePass not working in Start?

I know I can probably make this work by implementing a ScriptableRendererFeature, but the APIs I use in this snippet suit my use case better, and yet my custom ScriptableRenderPass never has Execute invoked:

Code (CSharp):

1.  
2. void Start() {
3.     _currentCamera = gameObject.GetComponent<Camera>();
4.     _customPass = new CustomPass();
5.     UniversalAdditionalCameraData cameraData = _currentCamera.GetUniversalAdditionalCameraData();
6.     cameraData.scriptableRenderer.EnqueuePass(_customPass);
7. }

(URP 7.3.1, Unity 2019.3.9f1)

 

The scriptable render pass array gets cleared every frame in UniversalRenderPipeline.RenderSingleCamera so what you're doing isn't going to work. I don't know that there is a way around it without making a scriptable render feature.

 

Ah, OK, thanks.
I had no idea the pass queue was cleared every frame, must have missed that in the docs.

 

Hmm, EnqueuePass (for after transparent) doesn't work from
RenderPipelineManager.beginCameraRendering, so I guess I have to make a ScriptableRenderFeature

 

Having the same problem here. I need to add passes dynamically from script but this breaks my coding architecture.
