# Objective
- Support WebGPU
- alternative to #5027 that doesn't need any async / await
- fixes#8315
- Surprise fix#7318
## Solution
### For async renderer initialisation
- Update the plugin lifecycle:
- app builds the plugin
- calls `plugin.build`
- registers the plugin
- app starts the event loop
- event loop waits for `ready` of all registered plugins in the same
order
- returns `true` by default
- then call all `finish` then all `cleanup` in the same order as
registered
- then execute the schedule
In the case of the renderer, to avoid anything async:
- building the renderer plugin creates a detached task that will send
back the initialised renderer through a mutex in a resource
- `ready` will wait for the renderer to be present in the resource
- `finish` will take that renderer and place it in the expected
resources by other plugins
- other plugins (that expect the renderer to be available) `finish` are
called and they are able to set up their pipelines
- `cleanup` is called, only custom one is still for pipeline rendering
### For WebGPU support
- update the `build-wasm-example` script to support passing `--api
webgpu` that will build the example with WebGPU support
- feature for webgl2 was always enabled when building for wasm. it's now
in the default feature list and enabled on all platforms, so check for
this feature must also check that the target_arch is `wasm32`
---
## Migration Guide
- `Plugin::setup` has been renamed `Plugin::cleanup`
- `Plugin::finish` has been added, and plugins adding pipelines should
do it in this function instead of `Plugin::build`
```rust
// Before
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>()
.init_resource::<OtherRenderResource>();
}
}
// After
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<OtherRenderResource>();
}
fn finish(&self, app: &mut App) {
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>();
}
}
```

# Objective
- Enabling AlphaMode::Opaque in the shader_prepass example crashes. The
issue seems to be that enabling opaque also generates vertex_uvs
Fixes https://github.com/bevyengine/bevy/issues/8273
## Solution
- Use the vertex_uvs in the shader if they are present
# Objective
- Mesh entities should cast shadows when not having Aabbs and having
NoFrustumCulling
- Fixes#8442
## Solution
- Mesh entities with NoFrustumCulling get no automatic Aabbs added
- Point and spot lights do not cull mesh entities for their shadow
mapping if they do not have an Aabb, but directional lights do
- Make directional lights not cull mesh entities from cascades if the do
not have Aabbs. So no Aabb as a consequence of a NoFrustumCulling
component will mean that those mesh entities are not culled and so are
visible to the light.
---
## Changelog
- Fixed: Mesh entities with NoFrustumCulling will cast shadows for
directional light shadow maps
# Objective
The default StandardMaterial values of `pbr_material.rs` and
`pbr_types.wgsl` are out of sync.
I think they are out of sync since
https://github.com/bevyengine/bevy/pull/7664.
## Solution
Adapt the values: `metallic = 0.0`, `perceptual_roughness = 0.5`.
Fixes issue mentioned in PR #8285.
_Note: By mistake, this is currently dependent on #8285_
# Objective
Ensure consistency in the spelling of the documentation.
Exceptions:
`crates/bevy_mikktspace/src/generated.rs` - Has not been changed from
licence to license as it is part of a licensing agreement.
Maybe for further consistency,
https://github.com/bevyengine/bevy-website should also be given a look.
## Solution
### Changed the spelling of the current words (UK/CN/AU -> US) :
cancelled -> canceled (Breaking API changes in #8285)
behaviour -> behavior (Breaking API changes in #8285)
neighbour -> neighbor
grey -> gray
recognise -> recognize
centre -> center
metres -> meters
colour -> color
### ~~Update [`engine_style_guide.md`]~~ Moved to #8324
---
## Changelog
Changed UK spellings in documentation to US
## Migration Guide

# Objective
The clippy lint `type_complexity` is known not to play well with bevy.
It frequently triggers when writing complex queries, and taking the
lint's advice of using a type alias almost always just obfuscates the
code with no benefit. Because of this, this lint is currently ignored in
CI, but unfortunately it still shows up when viewing bevy code in an
IDE.
As someone who's made a fair amount of pull requests to this repo, I
will say that this issue has been a consistent thorn in my side. Since
bevy code is filled with spurious, ignorable warnings, it can be very
difficult to spot the *real* warnings that must be fixed -- most of the
time I just ignore all warnings, only to later find out that one of them
was real after I'm done when CI runs.
## Solution
Suppress this lint in all bevy crates. This was previously attempted in
#7050, but the review process ended up making it more complicated than
it needs to be and landed on a subpar solution.
The discussion in https://github.com/rust-lang/rust-clippy/pull/10571
explores some better long-term solutions to this problem. Since there is
no timeline on when these solutions may land, we should resolve this
issue in the meantime by locally suppressing these lints.
### Unresolved issues
Currently, these lints are not suppressed in our examples, since that
would require suppressing the lint in every single source file. They are
still ignored in CI.
# Objective
- Closes https://github.com/bevyengine/bevy/issues/8008
## Solution
- Add a skybox plugin that renders a fullscreen triangle, and then
modifies the vertices in a vertex shader to enforce that it renders as a
skybox background.
- Skybox is run at the end of MainOpaquePass3dNode.
- In the future, it would be nice to get something like bevy_atmosphere
built-in, and have a default skybox+environment map light.
---
## Changelog
- Added `Skybox`.
- `EnvironmentMapLight` now renders in the correct orientation.
## Migration Guide
- Flip `EnvironmentMapLight` maps if needed to match how they previously
rendered (which was backwards).

# Objective
- We support enabling a normal prepass, but the main pass never actually
uses it and recomputes the normals in the main pass. This isn't ideal
since it's doing redundant work.
## Solution
- Use the normal texture from the prepass in the main pass
## Notes
~~I used `NORMAL_PREPASS_ENABLED` as a shader_def because
`NORMAL_PREPASS` is currently used to signify that it is running in the
prepass while this shader_def need to indicate the prepass is done and
the normal prepass was ran before. I'm not sure if there's a better way
to name this.~~
# Objective
Fixes#8089.
## Solution
Splits the MainPass3dNode into 2 nodes, one for the opaque + alpha
passes and one for the transparent pass.
---
## Changelog
- Split MainPass3dNode into MainOpaquePass3dNode and
MainTransparentPass3dNode
- Combine opaque and alpha phases in MainOpaquePass3dNode into one pass
- Create `START_MAIN_PASS` and `END_MAIN_PASS` empty nodes as labels
- Main pass becomes `START_MAIN_PASS -> MAIN_OPAQUE_PASS ->
MAIN_TRANSPARENT_PASS -> END_MAIN_PASS`
## Migration Guide
Nodes that previously added edges involving `MAIN_PASS` should now add
edges to or from `START_MAIN_PASS` or `END_MAIN_PASS` respectively.

# Objective
- Implement an alternative antialias technique
- TAA scales based off of view resolution, not geometry complexity
- TAA filters textures, firefly pixels, and other aliasing not covered
by MSAA
- TAA additionally will reduce noise / increase quality in future
stochastic rendering techniques
- Closes https://github.com/bevyengine/bevy/issues/3663
## Solution
- Add a temporal jitter component
- Add a motion vector prepass
- Add a TemporalAntialias component and plugin
- Combine existing MSAA and FXAA examples and add TAA
## Followup Work
- Prepass motion vector support for skinned meshes
- Move uniforms needed for motion vectors into a separate bind group,
instead of using different bind group layouts
- Reuse previous frame's GPU view buffer for motion vectors, instead of
recomputing
- Mip biasing for sharper textures, and or unjitter texture UVs

- Fixes#7965
- Code quality improvements.
- Removes the unreferenced function `dither` in pbr_functions.wgsl
introduced in 72fbcc7, but made obsolete in c069c54.
- Makes the reference to `screen_space_dither` in pbr.wgsl conditional
on `#ifdef TONEMAP_IN_SHADER`, as the required import is conditional on
the same, as deband dithering can only occur if tonemapping is also
occurring.
