This reverts commit 0b5302d96a.
# Objective
- Fixes#18158
- #17482 introduced rendering changes and was merged a bit too fast
## Solution
- Revert #17482 so that it can be redone and rendering changes discussed
before being merged. This will make it easier to compare changes with
main in the known "valid" state
This is not an issue with the work done in #17482 that is still
interesting
# Objective
Transparently uses simple `EnvironmentMapLight`s to mimic
`AmbientLight`s. Implements the first part of #17468, but I can
implement hemispherical lights in this PR too if needed.
## Solution
- A function `EnvironmentMapLight::solid_color(&mut Assets<Image>,
Color)` is provided to make an environment light with a solid color.
- A new system is added to `SimulationLightSystems` that maps
`AmbientLight`s on views or the world to a corresponding
`EnvironmentMapLight`.
I have never worked with (or on) Bevy before, so nitpicky comments on
how I did things are appreciated :).
## Testing
Testing was done on a modified version of the `3d/lighting` example,
where I removed all lights except the ambient light. I have not included
the example, but can if required.
## Migration
`bevy_pbr::AmbientLight` has been deprecated, so all usages of it should
be replaced by a `bevy_pbr::EnvironmentMapLight` created with
`EnvironmentMapLight::solid_color` placed on the camera. There is no
alternative to ambient lights as resources.
Fixes#17192.
Replaces "animated_fox" with "animated_mesh".
I considered a few different names - should it say "skinned_mesh" to be
precise? Should it mention gltf? But "animated_mesh" seems intuitive and
keeps it short.
## Testing
- Ran all three examples (Windows 10).
