Migrate cameras to required components (#15641)
# Objective Yet another PR for migrating stuff to required components. This time, cameras! ## Solution As per the [selected proposal](https://hackmd.io/tsYID4CGRiWxzsgawzxG_g#Combined-Proposal-1-Selected), deprecate `Camera2dBundle` and `Camera3dBundle` in favor of `Camera2d` and `Camera3d`. Adding a `Camera` without `Camera2d` or `Camera3d` now logs a warning, as suggested by Cart [on Discord](https://discord.com/channels/691052431525675048/1264881140007702558/1291506402832945273). I would personally like cameras to work a bit differently and be split into a few more components, to avoid some footguns and confusing semantics, but that is more controversial, and shouldn't block this core migration. ## Testing I ran a few 2D and 3D examples, and tried cameras with and without render graphs. --- ## Migration Guide `Camera2dBundle` and `Camera3dBundle` have been deprecated in favor of `Camera2d` and `Camera3d`. Inserting them will now also insert the other components required by them automatically. |

Migrate motion blur, TAA, SSAO, and SSR to required components (#15572)
# Objective Again, a step forward in the migration to required components: a bunch of camera rendering cormponents! Note that this does not include the camera components themselves yet, because the naming and API for `Camera` hasn't been fully decided yet. ## Solution As per the [selected proposals](https://hackmd.io/@bevy/required_components/%2FpiqD9GOdSFKZZGzzh3C7Uw): - Deprecate `MotionBlurBundle` in favor of the `MotionBlur` component - Deprecate `TemporalAntiAliasBundle` in favor of the `TemporalAntiAliasing` component - Deprecate `ScreenSpaceAmbientOcclusionBundle` in favor of the `ScreenSpaceAmbientOcclusion` component - Deprecate `ScreenSpaceReflectionsBundle` in favor of the `ScreenSpaceReflections` component --- ## Migration Guide `MotionBlurBundle`, `TemporalAntiAliasBundle`, `ScreenSpaceAmbientOcclusionBundle`, and `ScreenSpaceReflectionsBundle` have been deprecated in favor of the `MotionBlur`, `TemporalAntiAliasing`, `ScreenSpaceAmbientOcclusion`, and `ScreenSpaceReflections` components instead. Inserting them will now also insert the other components required by them automatically. |

Migrate meshes and materials to required components (#15524)
# Objective A big step in the migration to required components: meshes and materials! ## Solution As per the [selected proposal](https://hackmd.io/@bevy/required_components/%2Fj9-PnF-2QKK0on1KQ29UWQ): - Deprecate `MaterialMesh2dBundle`, `MaterialMeshBundle`, and `PbrBundle`. - Add `Mesh2d` and `Mesh3d` components, which wrap a `Handle<Mesh>`. - Add `MeshMaterial2d<M: Material2d>` and `MeshMaterial3d<M: Material>`, which wrap a `Handle<M>`. - Meshes *without* a mesh material should be rendered with a default material. The existence of a material is determined by `HasMaterial2d`/`HasMaterial3d`, which is required by `MeshMaterial2d`/`MeshMaterial3d`. This gets around problems with the generics. Previously: ```rust commands.spawn(MaterialMesh2dBundle { mesh: meshes.add(Circle::new(100.0)).into(), material: materials.add(Color::srgb(7.5, 0.0, 7.5)), transform: Transform::from_translation(Vec3::new(-200., 0., 0.)), ..default() }); ``` Now: ```rust commands.spawn(( Mesh2d(meshes.add(Circle::new(100.0))), MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))), Transform::from_translation(Vec3::new(-200., 0., 0.)), )); ``` If the mesh material is missing, previously nothing was rendered. Now, it renders a white default `ColorMaterial` in 2D and a `StandardMaterial` in 3D (this can be overridden). Below, only every other entity has a material:   Why white? This is still open for discussion, but I think white makes sense for a *default* material, while *invalid* asset handles pointing to nothing should have something like a pink material to indicate that something is broken (I don't handle that in this PR yet). This is kind of a mix of Godot and Unity: Godot just renders a white material for non-existent materials, while Unity renders nothing when no materials exist, but renders pink for invalid materials. I can also change the default material to pink if that is preferable though. ## Testing I ran some 2D and 3D examples to test if anything changed visually. I have not tested all examples or features yet however. If anyone wants to test more extensively, it would be appreciated! ## Implementation Notes - The relationship between `bevy_render` and `bevy_pbr` is weird here. `bevy_render` needs `Mesh3d` for its own systems, but `bevy_pbr` has all of the material logic, and `bevy_render` doesn't depend on it. I feel like the two crates should be refactored in some way, but I think that's out of scope for this PR. - I didn't migrate meshlets to required components yet. That can probably be done in a follow-up, as this is already a huge PR. - It is becoming increasingly clear to me that we really, *really* want to disallow raw asset handles as components. They caused me a *ton* of headache here already, and it took me a long time to find every place that queried for them or inserted them directly on entities, since there were no compiler errors for it. If we don't remove the `Component` derive, I expect raw asset handles to be a *huge* footgun for users as we transition to wrapper components, especially as handles as components have been the norm so far. I personally consider this to be a blocker for 0.15: we need to migrate to wrapper components for asset handles everywhere, and remove the `Component` derive. Also see https://github.com/bevyengine/bevy/issues/14124. --- ## Migration Guide Asset handles for meshes and mesh materials must now be wrapped in the `Mesh2d` and `MeshMaterial2d` or `Mesh3d` and `MeshMaterial3d` components for 2D and 3D respectively. Raw handles as components no longer render meshes. Additionally, `MaterialMesh2dBundle`, `MaterialMeshBundle`, and `PbrBundle` have been deprecated. Instead, use the mesh and material components directly. Previously: ```rust commands.spawn(MaterialMesh2dBundle { mesh: meshes.add(Circle::new(100.0)).into(), material: materials.add(Color::srgb(7.5, 0.0, 7.5)), transform: Transform::from_translation(Vec3::new(-200., 0., 0.)), ..default() }); ``` Now: ```rust commands.spawn(( Mesh2d(meshes.add(Circle::new(100.0))), MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))), Transform::from_translation(Vec3::new(-200., 0., 0.)), )); ``` If the mesh material is missing, a white default material is now used. Previously, nothing was rendered if the material was missing. The `WithMesh2d` and `WithMesh3d` query filter type aliases have also been removed. Simply use `With<Mesh2d>` or `With<Mesh3d>`. --------- Co-authored-by: Tim Blackbird <justthecooldude@gmail.com> Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

Migrate lights to required components (#15554)
# Objective Another step in the migration to required components: lights! Note that this does not include `EnvironmentMapLight` or reflection probes yet, because their API hasn't been fully chosen yet. ## Solution As per the [selected proposals](https://hackmd.io/@bevy/required_components/%2FLLnzwz9XTxiD7i2jiUXkJg): - Deprecate `PointLightBundle` in favor of the `PointLight` component - Deprecate `SpotLightBundle` in favor of the `PointLight` component - Deprecate `DirectionalLightBundle` in favor of the `DirectionalLight` component ## Testing I ran some examples with lights. --- ## Migration Guide `PointLightBundle`, `SpotLightBundle`, and `DirectionalLightBundle` have been deprecated. Use the `PointLight`, `SpotLight`, and `DirectionalLight` components instead. Adding them will now insert the other components required by them automatically. |

Rename rendering components for improved consistency and clarity (#15035)
# Objective The names of numerous rendering components in Bevy are inconsistent and a bit confusing. Relevant names include: - `AutoExposureSettings` - `AutoExposureSettingsUniform` - `BloomSettings` - `BloomUniform` (no `Settings`) - `BloomPrefilterSettings` - `ChromaticAberration` (no `Settings`) - `ContrastAdaptiveSharpeningSettings` - `DepthOfFieldSettings` - `DepthOfFieldUniform` (no `Settings`) - `FogSettings` - `SmaaSettings`, `Fxaa`, `TemporalAntiAliasSettings` (really inconsistent??) - `ScreenSpaceAmbientOcclusionSettings` - `ScreenSpaceReflectionsSettings` - `VolumetricFogSettings` Firstly, there's a lot of inconsistency between `Foo`/`FooSettings` and `FooUniform`/`FooSettingsUniform` and whether names are abbreviated or not. Secondly, the `Settings` post-fix seems unnecessary and a bit confusing semantically, since it makes it seem like the component is mostly just auxiliary configuration instead of the core *thing* that actually enables the feature. This will be an even bigger problem once bundles like `TemporalAntiAliasBundle` are deprecated in favor of required components, as users will expect a component named `TemporalAntiAlias` (or similar), not `TemporalAntiAliasSettings`. ## Solution Drop the `Settings` post-fix from the component names, and change some names to be more consistent. - `AutoExposure` - `AutoExposureUniform` - `Bloom` - `BloomUniform` - `BloomPrefilter` - `ChromaticAberration` - `ContrastAdaptiveSharpening` - `DepthOfField` - `DepthOfFieldUniform` - `DistanceFog` - `Smaa`, `Fxaa`, `TemporalAntiAliasing` (note: we might want to change to `Taa`, see "Discussion") - `ScreenSpaceAmbientOcclusion` - `ScreenSpaceReflections` - `VolumetricFog` I kept the old names as deprecated type aliases to make migration a bit less painful for users. We should remove them after the next release. (And let me know if I should just... not add them at all) I also added some very basic docs for a few types where they were missing, like on `Fxaa` and `DepthOfField`. ## Discussion - `TemporalAntiAliasing` is still inconsistent with `Smaa` and `Fxaa`. Consensus [on Discord](https://discord.com/channels/691052431525675048/743663924229963868/1280601167209955431) seemed to be that renaming to `Taa` would probably be fine, but I think it's a bit more controversial, and it would've required renaming a lot of related types like `TemporalAntiAliasNode`, `TemporalAntiAliasBundle`, and `TemporalAntiAliasPlugin`, so I think it's better to leave to a follow-up. - I think `Fog` should probably have a more specific name like `DistanceFog` considering it seems to be distinct from `VolumetricFog`. ~~This should probably be done in a follow-up though, so I just removed the `Settings` post-fix for now.~~ (done) --- ## Migration Guide Many rendering components have been renamed for improved consistency and clarity. - `AutoExposureSettings` → `AutoExposure` - `BloomSettings` → `Bloom` - `BloomPrefilterSettings` → `BloomPrefilter` - `ContrastAdaptiveSharpeningSettings` → `ContrastAdaptiveSharpening` - `DepthOfFieldSettings` → `DepthOfField` - `FogSettings` → `DistanceFog` - `SmaaSettings` → `Smaa` - `TemporalAntiAliasSettings` → `TemporalAntiAliasing` - `ScreenSpaceAmbientOcclusionSettings` → `ScreenSpaceAmbientOcclusion` - `ScreenSpaceReflectionsSettings` → `ScreenSpaceReflections` - `VolumetricFogSettings` → `VolumetricFog` --------- Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

Fix fog density texture offset seam (#14900)
# Objective - There is a flaw in the implementation of `FogVolume`'s `density_texture_offset` from #14868. Because of the way I am wrapping the UVW coordinates in the volumetric fog shader, a seam is visible when the 3d texture is wrapping around from one side to the other:  ## Solution - This PR fixes the issue by removing the wrapping from the shader and instead leaving it to the user to configure the 3d noise texture to use `ImageAddressMode::Repeat` if they want it to repeat. Using `ImageAddressMode::Repeat` is the proper solution to avoid the obvious seam:  - The sampler cannot be implicitly configured to use `ImageAddressMode::Repeat` because that's not always desirable. For example, the `fog_volumes` example wouldn't work properly because the texture from the edges of the volume would overflow to the other sides, which would be bad in this instance (but it's good in the case of the `scrolling_fog` example). So leaving it to the user to decide on their own whether they want the density texture to repeat seems to be the best solution. ## Testing - The `scrolling_fog` example still looks the same, it was just changed to explicitly declare that the density texture should be repeating when loading the asset. The `fog_volumes` example is unaffected. <details> <summary>Minimal reproduction example on current main</summary> <pre> use bevy::core_pipeline::experimental::taa::{TemporalAntiAliasBundle, TemporalAntiAliasPlugin}; use bevy::pbr::{FogVolume, VolumetricFogSettings, VolumetricLight}; use bevy::prelude::*;<br> fn main() { App::new() .add_plugins((DefaultPlugins, TemporalAntiAliasPlugin)) .add_systems(Startup, setup) .run(); }<br> fn setup(mut commands: Commands, assets: Res<AssetServer>) { commands.spawn(( Camera3dBundle { transform: Transform::from_xyz(3.5, -1.0, 0.4) .looking_at(Vec3::new(0.0, 0.0, 0.4), Vec3::Y), msaa: Msaa::Off, ..default() }, TemporalAntiAliasBundle::default(), VolumetricFogSettings { ambient_intensity: 0.0, jitter: 0.5, ..default() }, ));<br> commands.spawn(( DirectionalLightBundle { transform: Transform::from_xyz(-6.0, 5.0, -9.0) .looking_at(Vec3::new(0.0, 0.0, 0.0), Vec3::Y), directional_light: DirectionalLight { illuminance: 32_000.0, shadows_enabled: true, ..default() }, ..default() }, VolumetricLight, ));<br> commands.spawn(( SpatialBundle { visibility: Visibility::Visible, transform: Transform::from_xyz(0.0, 0.0, 0.0).with_scale(Vec3::splat(3.0)), ..default() }, FogVolume { density_texture: Some(assets.load("volumes/fog_noise.ktx2")), density_texture_offset: Vec3::new(0.0, 0.0, 0.4), scattering: 1.0, ..default() }, )); } </pre> </details> |

Allow fog density texture to be scrolled over time with an offset (#14868)
# Objective - The goal of this PR is to make it possible to move the density texture of a `FogVolume` over time in order to create dynamic effects like fog moving in the wind. - You could theoretically move the `FogVolume` itself, but this is not ideal, because the `FogVolume` AABB would eventually leave the area. If you want an area to remain foggy while also creating the impression that the fog is moving in the wind, a scrolling density texture is a better solution. ## Solution - The PR adds a `density_texture_offset` field to the `FogVolume` component. This offset is in the UVW coordinates of the density texture, meaning that a value of `(0.5, 0.0, 0.0)` moves the 3d texture by half along the x-axis. - Values above 1.0 are wrapped, a 1.5 offset is the same as a 0.5 offset. This makes it so that the density texture wraps around on the other side, meaning that a repeating 3d noise texture can seamlessly scroll forever. It also makes it easy to move the density texture over time by simply increasing the offset every frame. ## Testing - A `scrolling_fog` example has been added to demonstrate the feature. It uses the offset to scroll a repeating 3d noise density texture to create the impression of fog moving in the wind. - The camera is looking at a pillar with the sun peaking behind it. This highlights the effect the changing density has on the volumetric lighting interactions. - Temporal anti-aliasing combined with the `jitter` option of `VolumetricFogSettings` is used to improve the quality of the effect. --- ## Showcase https://github.com/user-attachments/assets/3aa50ebd-771c-4c99-ab5d-255c0c3be1a8 |
