improve shader import model (#5703) # Objective operate on naga IR directly to improve handling of shader modules. - give codespan reporting into imported modules - allow glsl to be used from wgsl and vice-versa the ultimate objective is to make it possible to - provide user hooks for core shader functions (to modify light behaviour within the standard pbr pipeline, for example) - make automatic binding slot allocation possible but ... since this is already big, adds some value and (i think) is at feature parity with the existing code, i wanted to push this now. ## Solution i made a crate called naga_oil (https://github.com/robtfm/naga_oil - unpublished for now, could be part of bevy) which manages modules by - building each module independantly to naga IR - creating "header" files for each supported language, which are used to build dependent modules/shaders - make final shaders by combining the shader IR with the IR for imported modules then integrated this into bevy, replacing some of the existing shader processing stuff. also reworked examples to reflect this. ## Migration Guide shaders that don't use `#import` directives should work without changes. the most notable user-facing difference is that imported functions/variables/etc need to be qualified at point of use, and there's no "leakage" of visible stuff into your shader scope from the imports of your imports, so if you used things imported by your imports, you now need to import them directly and qualify them. the current strategy of including/'spreading' `mesh_vertex_output` directly into a struct doesn't work any more, so these need to be modified as per the examples (e.g. color_material.wgsl, or many others). mesh data is assumed to be in bindgroup 2 by default, if mesh data is bound into bindgroup 1 instead then the shader def `MESH_BINDGROUP_1` needs to be added to the pipeline shader_defs.

Work around naga/wgpu WGSL instance_index -> GLSL gl_InstanceID bug on WebGL2 (#9383) naga and wgpu should polyfill WGSL instance_index functionality where it is not available in GLSL. Until that is done, we can work around it in bevy using a push constant which is converted to a uniform by naga and wgpu. # Objective - Fixes #9375 ## Solution - Use a push constant to pass in the base instance to the shader on WebGL2 so that base instance + gl_InstanceID is used to correctly represent the instance index. ## TODO - [ ] Benchmark vs per-object dynamic offset MeshUniform as this will now push a uniform value per-draw as well as update the dynamic offset per-batch. - [x] Test on DX12 AMD/NVIDIA to check that this PR does not regress any problems that were observed there. (@Elabajaba @robtfm were testing that last time - help appreciated. <3 ) --- ## Changelog - Added: `bevy_render::instance_index` shader import which includes a workaround for the lack of a WGSL `instance_index` polyfill for WebGL2 in naga and wgpu for the time being. It uses a push_constant which gets converted to a plain uniform by naga and wgpu. ## Migration Guide Shader code before: ``` struct Vertex { @builtin(instance_index) instance_index: u32, ... } @vertex fn vertex(vertex_no_morph: Vertex) -> VertexOutput { ... var model = mesh[vertex_no_morph.instance_index].model; ``` After: ``` #import bevy_render::instance_index struct Vertex { @builtin(instance_index) instance_index: u32, ... } @vertex fn vertex(vertex_no_morph: Vertex) -> VertexOutput { ... var model = mesh[bevy_render::instance_index::get_instance_index(vertex_no_morph.instance_index)].model; ```

Use GpuArrayBuffer for MeshUniform (#9254) # Objective - Reduce the number of rebindings to enable batching of draw commands ## Solution - Use the new `GpuArrayBuffer` for `MeshUniform` data to store all `MeshUniform` data in arrays within fewer bindings - Sort opaque/alpha mask prepass, opaque/alpha mask main, and shadow phases also by the batch per-object data binding dynamic offset to improve performance on WebGL2. --- ## Changelog - Changed: Per-object `MeshUniform` data is now managed by `GpuArrayBuffer` as arrays in buffers that need to be indexed into. ## Migration Guide Accessing the `model` member of an individual mesh object's shader `Mesh` struct the old way where each `MeshUniform` was stored at its own dynamic offset: ```rust struct Vertex { @location(0) position: vec3<f32>, }; fn vertex(vertex: Vertex) -> VertexOutput { var out: VertexOutput; out.clip_position = mesh_position_local_to_clip( mesh.model, vec4<f32>(vertex.position, 1.0) ); return out; } ``` The new way where one needs to index into the array of `Mesh`es for the batch: ```rust struct Vertex { @builtin(instance_index) instance_index: u32, @location(0) position: vec3<f32>, }; fn vertex(vertex: Vertex) -> VertexOutput { var out: VertexOutput; out.clip_position = mesh_position_local_to_clip( mesh[vertex.instance_index].model, vec4<f32>(vertex.position, 1.0) ); return out; } ``` Note that using the instance_index is the default way to pass the per-object index into the shader, but if you wish to do custom rendering approaches you can pass it in however you like. --------- Co-authored-by: robtfm <50659922+robtfm@users.noreply.github.com> Co-authored-by: Elabajaba <Elabajaba@users.noreply.github.com>

Mesh Skinning. Attempt #3 (#4238) # Objective Load skeletal weights and indices from GLTF files. Animate meshes. ## Solution - Load skeletal weights and indices from GLTF files. - Added `SkinnedMesh` component and ` SkinnedMeshInverseBindPose` asset - Added `extract_skinned_meshes` to extract joint matrices. - Added queue phase systems for enqueuing the buffer writes. Some notes: - This ports part of # #2359 to the current main. - This generates new `BufferVec`s and bind groups every frame. The expectation here is that the number of `Query::get` calls during extract is probably going to be the stronger bottleneck, with up to 256 calls per skinned mesh. Until that is optimized, caching buffers and bind groups is probably a non-concern. - Unfortunately, due to the uniform size requirements, this means a 16KB buffer is allocated for every skinned mesh every frame. There's probably a few ways to get around this, but most of them require either compute shaders or storage buffers, which are both incompatible with WebGL2.

update wgpu to 0.13 (#5168) # Objective - Update wgpu to 0.13 - ~~Wait, is wgpu 0.13 released? No, but I had most of the changes already ready since playing with webgpu~~ well it has been released now - Also update parking_lot to 0.12 and naga to 0.9 ## Solution - Update syntax for wgsl shaders https://github.com/gfx-rs/wgpu/blob/master/CHANGELOG.md#wgsl-syntax - Add a few options, remove some references: https://github.com/gfx-rs/wgpu/blob/master/CHANGELOG.md#other-breaking-changes - fragment inputs should now exactly match vertex outputs for locations, so I added exports for those to be able to reuse them https://github.com/gfx-rs/wgpu/pull/2704

update wireframe rendering to new renderer (#3193) Updates the wireframe rendering initialliy implemented in https://github.com/bevyengine/bevy/pull/562 to the new renderer. It lives in `bevy_pbr2` instead of `bevy_render2` because that way it can reuse the `MeshPipeline`.
