# Objective
Fix gltf validation errors in `Fox.glb`.
Inspired by #8099, but that issue doesn't appear to describe a real bug
to fix, as far as I can tell.
## Solution
Use the latest version of the Fox from
[glTF-Sample-Assets](https://github.com/KhronosGroup/glTF-Sample-Assets/blob/main/Models/Fox/glTF-Binary/Fox.glb).
## Testing
Dropped both versions in https://github.khronos.org/glTF-Validator/
`cargo run --example animated_mesh` seems to still look fine.
Before:
```
The asset contains errors.
"numErrors": 126,
"numWarnings": 4184,
```
After:
```
The asset is valid.
"numErrors": 0,
"numWarnings": 0,
```
## Discussion
The 3d testbed was panicking with
```
thread 'main' panicked at examples/testbed/3d.rs:288:60:
called `Result::unwrap()` on an `Err` value: QueryDoesNotMatch(35v1 with components Transform, GlobalTransform, Visibility, InheritedVisibility, ViewVisibility, ChildOf, Children, Name)
```
Which is bizarre. I think this might be related to #17720, or maybe the
structure of the gltf changed.
I fixed it by using updating the testbed to use a more robust method of
finding the correct entity as is done in `animated_mesh`.
