# Objective
- Fixes https://github.com/bevyengine/bevy/issues/15871
(Camera is done in #15946)
## Solution
- Do the same as #15904 for other extraction systems
- Added missing `SyncComponentPlugin` for DOF, TAA, and SSAO
(According to the
[documentation](https://dev-docs.bevyengine.org/bevy/render/sync_component/struct.SyncComponentPlugin.html),
this plugin "needs to be added for manual extraction implementations."
We may need to check this is done.)
## Testing
Modified example locally to add toggles if not exist.
- [x] DOF - toggling DOF component and perspective in `depth_of_field`
example
- [x] TAA - toggling `Camera.is_active` and TAA component
- [x] clusters - not entirely sure, toggling `Camera.is_active` in
`many_lights` example (no crash/glitch even without this PR)
- [x] previous_view - toggling `Camera.is_active` in `skybox` (no
crash/glitch even without this PR)
- [x] lights - toggling `Visibility` of `DirectionalLight` in `lighting`
example
- [x] SSAO - toggling `Camera.is_active` and SSAO component in `ssao`
example
- [x] default UI camera view - toggling `Camera.is_active` (nop without
#15946 because UI defaults to some camera even if `DefaultCameraView` is
not there)
- [x] volumetric fog - toggling existence of volumetric light. Looks
like optimization, no change in behavior/visuals
