# Objective
- Progress towards #19887.
## Solution
- Convert `FromWorld` impls into systems.
- Run those systems in `RenderStartup`.
## Testing
- Ran `bloom_3d`, `auto_exposure`, `depth_of_field`, `motion_blur`,
`skybox`, `post_processing`, and `tonemapping` examples and they all
work :)
# Objective
- Progress towards #19887.
## Solution
- Convert FromWorld implementations into systems.
- Move any resource "manipulation" from `Plugin::finish` to systems.
- Add `after` dependencies to any uses of these resources (basically all
`SpritePipeline`).
## Testing
- Ran the `sprite`, and `mesh2d_manual` example and it worked.
# Objective
- Progress towards #19887.
## Solution
- For cases that don't need to conditionally add systems, we can just
replace FromWorld impls with systems and then add those systems to
`RenderStartup`.
## Testing
- I ran the `lightmaps`, `reflection_probes`, `deferred_rendering`,
`volumetric_fog`, and `wireframe` examples.
