# Objective - Split PBR and 2D mesh shaders into types and bindings to prepare the shaders to be more reusable. - See #3969 for details. I'm doing this in multiple steps to make review easier. --- ## Changelog - Changed: 2D and PBR mesh shaders are now split into types and bindings, the following shader imports are available: `bevy_pbr::mesh_view_types`, `bevy_pbr::mesh_view_bindings`, `bevy_pbr::mesh_types`, `bevy_pbr::mesh_bindings`, `bevy_sprite::mesh2d_view_types`, `bevy_sprite::mesh2d_view_bindings`, `bevy_sprite::mesh2d_types`, `bevy_sprite::mesh2d_bindings` ## Migration Guide - In shaders for 3D meshes: - `#import bevy_pbr::mesh_view_bind_group` -> `#import bevy_pbr::mesh_view_bindings` - `#import bevy_pbr::mesh_struct` -> `#import bevy_pbr::mesh_types` - NOTE: If you are using the mesh bind group at bind group index 2, you can remove those binding statements in your shader and just use `#import bevy_pbr::mesh_bindings` which itself imports the mesh types needed for the bindings. - In shaders for 2D meshes: - `#import bevy_sprite::mesh2d_view_bind_group` -> `#import bevy_sprite::mesh2d_view_bindings` - `#import bevy_sprite::mesh2d_struct` -> `#import bevy_sprite::mesh2d_types` - NOTE: If you are using the mesh2d bind group at bind group index 2, you can remove those binding statements in your shader and just use `#import bevy_sprite::mesh2d_bindings` which itself imports the mesh2d types needed for the bindings.
