Hi, I have a GLTF where each mesh has a unique name (stored in the mesh.name field) that is used as an index to a property database to describe the application specific properties of that mesh. During the tiling process (I’m using the model-tiler), the mesh’s name is lost (I think all meshes have the same name as ‘mesh\_0’ after the conversion). Is there a way to change the behavior?

I heard there are some upcoming updates in 3D Tile Next that can support per-vertex, per-mesh metadata, is there some good example describing how this is implemented, i.e. how such metadata is added to the tiles using what tiling tool and how the runtime get those metadata from the 3D tiles?

Thanks!
