4. Observe the Console
Expected result: No exceptions are thrown
Actual result: “NullReferenceException: Object reference not set to an instance of an object.” exceptions are constantly thrown
Reproducible with: 6000.0.22f1
Couldn’t test with: 2021.3.44f1, 2022.3.49f (RenderGraph is not supported)
Reproducible on: Windows 11
Not reproducible on: No other environment tested
Note:
- The Renderer Feature was created following the documentation: [https://docs.unity3d.com/6000.0/Documentation/Manual/urp/renderer-features/create-custom-renderer-feature.html|https://docs.unity3d.com/6000.0/Documentation/Manual/urp/renderer-features/create-custom-renderer-feature.html|smart-link]

Resolution Note:
There is an issue in BlurRenderPass.cs:
public override void OnCameraCleanup(CommandBuffer cmd)
{
cmd.Release(); // <-- This is the cause of the NullPointerException
}
Removing the OnCameraCleanup override function and/or the call to cmd.Release() fixes the issue.
Calling cmd.Release() destroys the internal CommandBuffer's representation, so when the outer call the EndSample is triggered from the Dispose, the underlying internal representation was released and set to null causing the error. The CommandBuffer is shared between passes, so Release() should not be called manually.
