## What you did

```rust
use bevy::{

pbr::{Atmosphere, AtmosphereSettings},
prelude::*,
};

fn main() {
App::new()
.add_plugins(DefaultPlugins)

.run();
}

fn setup(
mut commands: Commands,
mut meshes: ResMut>,
mut materials: ResMut>,
) {
commands.spawn((
Camera3d::default(),
Camera {
hdr: true,
..Default::default()
},
Atmosphere::EARTH,
AtmosphereSettings::default(),
Bloom::NATURAL,
Transform::from_xyz(2.5, 0., 10.).looking_at(Vec3::new(2.5, 0., 0.), Vec3::Y),
));

commands.spawn((
DirectionalLight::default(),
Transform::from_xyz(0., 5., 0.).looking_at(Vec3::ZERO, Vec3::NEG_Z),
));

commands.spawn((
Mesh3d(meshes.add(Plane3d::new(Vec3::Y, Vec2::splat(5.)))),
MeshMaterial3d(materials.add(Color::from(palettes::tailwind::BLUE_400).with_alpha(0.5))),
Transform::from_xyz(0., -3., 0.),
));
commands.spawn((
Mesh3d(meshes.add(Plane3d::new(Vec3::Y, Vec2::splat(5.)))),
MeshMaterial3d(materials.add(Color::from(palettes::tailwind::GREEN_800))),
Transform::from_xyz(0., -4., 0.),
));
commands.spawn((
Mesh3d(meshes.add(Cuboid::new(1., 5., 1.).mesh().build())),
MeshMaterial3d(materials.add(Color::WHITE)),
Transform::from_xyz(2.5, -5., -5.),
));
}

fn bob(mut camera: Single<&mut Transform, With>, time: Res) {
**camera = Transform::from_xyz(2.5, 2. * ops::sin(time.elapsed_secs()), 10.)
.looking_at(Vec3::new(2.5, 0., 0.), Vec3::Y);
}
```

## What went wrong

Parts of the transparent mesh don't render when below sea level (Y<0) with Atmosphere on
