# Objective
- fixes https://github.com/bevyengine/bevy/issues/13473
## Solution
- When a single mesh is assigned multiple materials, it is divided into
several primitive nodes, with each primitive assigned a unique material.
Presently, these primitives are named using the format Mesh.index, which
complicates querying. To improve this, we can assign a specific name to
each primitive based on the material’s name, since each primitive
corresponds to one material exclusively.
## Testing
- I have included a simple example which shows how to query a material
and mesh part based on the new name component.
## Changelog
- adds `GltfMaterialName` component to the mesh entity of the gltf
primitive node.
