# Objective
update the `load_gltf_extras.rs` example to the newest bevy api
## Solution
uses the new type-safe code for loading the scene #0 from the gltf
instead of a path suffix
## Testing
the example runs as expected
# Objective
- fixes#4823
## Solution
As outlined in the discussion in the linked issue as the best current
solution, this PR adds specific GltfExtras for
- scenes
- meshes
- materials
- As it is , it is not a breaking change, I hesitated to rename the
current "GltfExtras" component to "PrimitiveGltfExtras", but that would
result in a breaking change and might be a bit confusing as to what
"primitive" that refers to.
## Testing
- I included a bare-bones example & asset (exported gltf file from
Blender) with gltf extras at all the relevant levels : scene, mesh,
material
---
## Changelog
- adds "SceneGltfExtras" injected at the scene level if any
- adds "MeshGltfExtras", injected at the mesh level if any
- adds "MaterialGltfExtras", injected at the mesh level if any: ie if a
mesh has a material that has gltf extras, the component will be injected
there.
