If your bug is rendering-related, copy the adapter info that appears when you run Bevy.

` AdapterInfo { name: "NVIDIA GeForce RTX 2060", vendor: 4318, device: 7817, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "560.94", backend: Vulkan }`

What you did

In my game i have 3 cameras, one is rendering the world, other is rendering the view model and an ui camera. I added bloom to world camera and world camera started not rendering anything.

What went wrong

World camera stopped rendering after adding Bloom::NATURAL

Additional information

My camera setup:

    commands
        .spawn((
            Name::new("Player Camera"),
            ViewVisibility::default(),
            Visibility::default(),
            MainCamera, 
            AccumalatedCameraInput::default(),
            CameraRecoil::default(),
            Transform::from_xyz(0.0, 0.0, 0.0),
        ))
        .with_children(|parent| {
            parent.spawn((
                Camera3d::default(),
                Camera {
                    order: 0,
                    clear_color: ClearColorConfig::Default,
                    ..default()
                },
                RenderLayers::from_layers(&[LAYER_DEFAULT, LAYER_PARTICLES]),
                WorldCamera::default(),
                Bloom::NATURAL,
                Tonemapping::TonyMcMapface,
                Name::new("World Camera"),
            ));
            parent.spawn((
                Camera3d::default(),
                Camera {
                    order: 1,
                    ..default()
                },
                Projection::Perspective(PerspectiveProjection {
                    fov: 70.0_f32.to_radians(), // Wider FOV for viewmodel
                    ..default()
                }),
                ViewModelCamera,
                RenderLayers::from_layers(&[LAYER_VIEWMODEL, LAYER_PARTICLES]),
                Name::new("ViewModel Camera"),
            ));
        });

I fixed the issue adding Hdr::default( ) to other cameras, that fixed rendering problem but its unintuitive and not documented.

[PhantomMorrigan]

Applies a bloom effect to an HDR-enabled 2d or 3d camera.

From the documention for Bloom.

If this doesn't explain the Issue, please try wording it a bit more clearly.

It sounds like the problem is that all of the cameras seem to need HDR, rather than just the one that's intending to show bloom.
