GLB model renders incorrectly

In game:

In blender:

Thanks for sharing the code, however please provide it as actual code. Markdown supports code blocks, e.g.

```rust
fn main(){}
```

results in

fn main()

Please also provide what bevy version you are using. I suspect the problem is some issue of winding direction or backface culling, but I'm not certain.

Thanks, but, I'm aware, just didn't think it was necessary.

    commands.insert_resource(audio_state);

    commands.spawn_scene(asset_server.load("models/parappa.glb#Scene0"));

    commands.spawn_bundle(PbrBundle {
        mesh: meshes.add(Mesh::from(shape::Plane { size: 5.0 })),
        material: materials.add(Color::rgb(0.3, 0.5, 0.3).into()),
        ..Default::default()
    });

    commands.spawn_bundle(PointLightBundle {
        transform: Transform::from_xyz(4.0, 8.0, 4.0),
        ..Default::default()
    });
    commands.spawn_bundle(PerspectiveCameraBundle {
        transform: Transform::from_xyz(-2.0, 2.5, 5.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..Default::default()
    });
    commands.spawn_bundle(UiCameraBundle::default());

    asset_server.watch_for_changes().unwrap();

Viewing this model in '3d viewer' gives
in the 'stats and shading' tab

Looking from the back gives:

i.e. the opposite. Therefore, your model is being correctly backface culled. I'm not sure how to disable it, unfortunately. Hopefully someone more experienced can chime in.

It's supposed to have a back face btw

Blender can turn on or off backface culling. Game engines often can't. A solution I often do is to duplicate the vertices and flip their normals.

[lukors]

I took a look at the model. Turn on backface culling in Blender and you will see the issue.

This model is not rendering incorrectly in Bevy. :)

Huh... Sorry, I'm new to 3D rendering. This stuff reads like hieroglyphs to me
