Is there any way to do a single Camera.Render() with URP?

Right now, a feature in our game relies on being able to disable some effects, then manually render one camera into a render texture, then re-enable the effects. all in one frame.

Is there any way to do this with the URP or not at all? Camera.Render() hook is listed as "not supported" and without this feature we can't really upgrade to URP at all.

Also, bonus question: Would our game theoretically be able to run on a Nintendo Switch with the built-in render pipeline?

 

Thanks for asking this question, kbm.

What Context do you pass RenderSingleCamera? I'm using it to render one frame of a secondary camera. I can't find any examples of its use.

Thanks in advance for any assistance!

I case you haven't figured this out, I ran into the same problem, just paying forward the help I was offered!

using UnityEngine.Rendering;

using UnityEngine.Rendering.Universal;

using RenderPipeline = UnityEngine.Rendering.RenderPipelineManager;

...



    private void OnEnable()

    {

        RenderPipeline.beginCameraRendering += UpdateCamera;

    }

...

    void UpdateCamera(ScriptableRenderContext SRC, Camera camera)

    {

...

        UniversalRenderPipeline.RenderSingleCamera(SRC, portalCamera);

...

    }

 

Is there a way to do this from an editor script?

(Just trying to render a texture from a temporary camera and save it to a file, something that used to work with camera.Render() with the classic render pipeline)

edit: Got it working after discovering the editor coroutines package, and using a coroutine to just wait a frame for the camera to render itself

 

The boat attack demo uses camera.Render() with URP, to capture the heightmap in editor and when starting game. So it may works in editor, with extra load.

Interesting. Might have just been a Graphics.CopyTexture (from RenderTexture to saveable Texture2D) not working as expected when I tried that then, as I ended up switching to Texture2D.ReadPixels to get the coroutine version working.
