Exposure settings (adopted) (#11347)
Rebased and finished version of https://github.com/bevyengine/bevy/pull/8407. Huge thanks to @GitGhillie for adjusting all the examples, and the many other people who helped write this PR (@superdump , @coreh , among others) :) Fixes https://github.com/bevyengine/bevy/issues/8369 --- ## Changelog - Added a `brightness` control to `Skybox`. - Added an `intensity` control to `EnvironmentMapLight`. - Added `ExposureSettings` and `PhysicalCameraParameters` for controlling exposure of 3D cameras. - Removed the baked-in `DirectionalLight` exposure Bevy previously hardcoded internally. ## Migration Guide - If using a `Skybox` or `EnvironmentMapLight`, use the new `brightness` and `intensity` controls to adjust their strength. - All 3D scene will now have different apparent brightnesses due to Bevy implementing proper exposure controls. You will have to adjust the intensity of your lights and/or your camera exposure via the new `ExposureSettings` component to compensate. --------- Co-authored-by: Robert Swain <robert.swain@gmail.com> Co-authored-by: GitGhillie <jillisnoordhoek@gmail.com> Co-authored-by: Marco Buono <thecoreh@gmail.com> Co-authored-by: vero <email@atlasdostal.com> Co-authored-by: atlas dostal <rodol@rivalrebels.com> |

Fix intra-doc link warnings (#10445)

Fix CI for Rust 1.72 (#9562)
# Objective [Rust 1.72.0](https://blog.rust-lang.org/2023/08/24/Rust-1.72.0.html) is now stable. # Notes - `let-else` formatting has arrived! - I chose to allow `explicit_iter_loop` due to https://github.com/rust-lang/rust-clippy/issues/11074. We didn't hit any of the false positives that prevent compilation, but fixing this did produce a lot of the "symbol soup" mentioned, e.g. `for image in &mut *image_events {`. Happy to undo this if there's consensus the other way. --------- Co-authored-by: François <mockersf@gmail.com> |

Add morph targets (#8158)
# Objective - Add morph targets to `bevy_pbr` (closes #5756) & load them from glTF - Supersedes #3722 - Fixes #6814 [Morph targets][1] (also known as shape interpolation, shape keys, or blend shapes) allow animating individual vertices with fine grained controls. This is typically used for facial expressions. By specifying multiple poses as vertex offset, and providing a set of weight of each pose, it is possible to define surprisingly realistic transitions between poses. Blending between multiple poses also allow composition. Morph targets are part of the [gltf standard][2] and are a feature of Unity and Unreal, and babylone.js, it is only natural to implement them in bevy. ## Solution This implementation of morph targets uses a 3d texture where each pixel is a component of an animated attribute. Each layer is a different target. We use a 2d texture for each target, because the number of attribute×components×animated vertices is expected to always exceed the maximum pixel row size limit of webGL2. It copies fairly closely the way skinning is implemented on the CPU side, while on the GPU side, the shader morph target implementation is a relatively trivial detail. We add an optional `morph_texture` to the `Mesh` struct. The `morph_texture` is built through a method that accepts an iterator over attribute buffers. The `MorphWeights` component, user-accessible, controls the blend of poses used by mesh instances (so that multiple copy of the same mesh may have different weights), all the weights are uploaded to a uniform buffer of 256 `f32`. We limit to 16 poses per mesh, and a total of 256 poses.

This allows controlling several mesh primitives through a unique entity _as per GLTF spec_. - Add `MorphTargetNames` component, naming each indices of loaded morph targets. - Load morph targets weights and buffers in `bevy_gltf` - handle morph targets animations in `bevy_animation` (previously, it was a `warn!` log) - Add the `MorphStressTest.gltf` asset for morph targets testing, taken from the glTF samples repo, CC0. - Add morph target manipulation to `scene_viewer` - Separate the animation code in `scene_viewer` from the rest of the code, reducing `#[cfg(feature)]` noise - Add the `morph_targets.rs` example to show off how to manipulate morph targets, loading `MorpStressTest.gltf` ## Migration Guide - (very specialized, unlikely to be touched by 3rd parties) - `MeshPipeline` now has a single `mesh_layouts` field rather than separate `mesh_layout` and `skinned_mesh_layout` fields. You should handle all possible mesh bind group layouts in your implementation - You should also handle properly the new `MORPH_TARGETS` shader def and mesh pipeline key. A new function is exposed to make this easier: `setup_moprh_and_skinning_defs` - The `MeshBindGroup` is now `MeshBindGroups`, cached bind groups are now accessed through the `get` method.
