title: "Invert `bevy_gltf` dependency with `bevy_pbr`"
pull_requests: [22569]

---

Previously, bevy_gltf depended on bevy_pbr. This meant scene definition was tightly coupled to rendering. This dependency has been inverted, to allow bevy_gltf to function without any of the rendering stack present.

You can disable PBR rendering by initializing PbrPlugin as so:

PbrPlugin {
    gltf_render_enabled: false,
    ..Default::default()
}

GltfExtensionHandler trait's methods have been updated:

• on_material passes in the material_asset : &GltfMaterial and material_label: &str

• on_spawn_mesh_and_material also passes in the material_label: &str

UvChannel has moved from bevy_pbr to bevy_mesh.
