update shader imports (#10180) # Objective - bump naga_oil to 0.10 - update shader imports to use rusty syntax ## Migration Guide naga_oil 0.10 reworks the import mechanism to support more syntax to make it more rusty, and test for item use before importing to determine which imports are modules and which are items, which allows: - use rust-style imports ``` #import bevy_pbr::{ pbr_functions::{alpha_discard as discard, apply_pbr_lighting}, mesh_bindings, } ``` - import partial paths: ``` #import part::of::path ... path::remainder::function(); ``` which will call to `part::of::path::remainder::function` - use fully qualified paths without importing: ``` // #import bevy_pbr::pbr_functions bevy_pbr::pbr_functions::pbr() ``` - use imported items without qualifying ``` #import bevy_pbr::pbr_functions::pbr // for backwards compatibility the old style is still supported: // #import bevy_pbr::pbr_functions pbr ... pbr() ``` - allows most imported items to end with `_` and numbers (naga_oil#30). still doesn't allow struct members to end with `_` or numbers but it's progress. - the vast majority of existing shader code will work without changes, but will emit "deprecated" warnings for old-style imports. these can be suppressed with the `allow-deprecated` feature. - partly breaks overrides (as far as i'm aware nobody uses these yet) - now overrides will only be applied if the overriding module is added as an additional import in the arguments to `Composer::make_naga_module` or `Composer::add_composable_module`. this is necessary to support determining whether imports are modules or items.

Expand `FallbackImage` to include a `GpuImage` for each possible `TextureViewDimension` (#6974) # Objective Fixes #6920 ## Solution From the issue discussion: > From looking at the `AsBindGroup` derive macro implementation, the fallback image's `TextureView` is used when the binding's `Option<Handle<Image>>` is `None`. Because this relies on already having a view that matches the desired binding dimensions, I think the solution will require creating a separate `GpuImage` for each possible `TextureViewDimension`. --- ## Changelog Users can now rely on `FallbackImage` to work with a texture binding of any dimension.

Swap material and mesh bind groups (#10485) # Objective - Materials should be a more frequent rebind then meshes (due to being able to use a single vertex buffer, such as in #10164) and therefore should be in a higher bind group. --- ## Changelog - For 2d and 3d mesh/material setups (but not UI materials, or other rendering setups such as gizmos, sprites, or text), mesh data is now in bind group 1, and material data is now in bind group 2, which is swapped from how they were before. ## Migration Guide - Custom 2d and 3d mesh/material shaders should now use bind group 2 `@group(2) @binding(x)` for their bound resources, instead of bind group 1. - Many internal pieces of rendering code have changed so that mesh data is now in bind group 1, and material data is now in bind group 2. Semi-custom rendering setups (that don't use the Material or Material2d APIs) should adapt to these changes.

pbr shader cleanup (#10105) # Objective cleanup some pbr shader code. improve shader stage io consistency and make pbr.wgsl (probably many people's first foray into bevy shader code) a little more human-readable. also fix a couple of small issues with deferred rendering. ## Solution mesh_vertex_output: - rename to forward_io (to align with prepass_io) - rename `MeshVertexOutput` to `VertexOutput` (to align with prepass_io) - move `Vertex` from mesh.wgsl into here (to align with prepass_io) prepass_io: - remove `FragmentInput`, use `VertexOutput` directly (to align with forward_io) - rename `VertexOutput::clip_position` to `position` (to align with forward_io) pbr.wgsl: - restructure so we don't need `#ifdefs` on the actual entrypoint, use VertexOutput and FragmentOutput in all cases and use #ifdefs to import the right struct definitions. - rearrange to make the flow clearer - move alpha_discard up from `pbr_functions::pbr` to avoid needing to call it on some branches and not others - add a bunch of comments deferred_lighting: - move ssao into the `!unlit` block to reflect forward behaviour correctly - fix compile error with deferred + premultiply_alpha ## Migration Guide in custom material shaders: - `pbr_functions::pbr` no longer calls to `pbr_functions::alpha_discard`. if you were using the `pbr` function in a custom shader with alpha mask mode you now also need to call alpha_discard manually - rename imports of `bevy_pbr::mesh_vertex_output` to `bevy_pbr::forward_io` - rename instances of `MeshVertexOutput` to `VertexOutput` in custom material prepass shaders: - rename instances of `VertexOutput::clip_position` to `VertexOutput::position`
