gltf is rendered without texture

[xbz-24]

this is my project structure

    commands.spawn(SceneBundle{
        scene: asset_server.load("gltf/scene.gltf#Scene0"),
        ..default()
    });

[xbz-24]

gltf/scene.gltf is the scene its loading, and its correct but I need this whole whole model to use this aqua_diffuse.png

like this

[xbz-24]

im just doing in main:

fn main() {
    let mut app = App::new();
    app.add_plugins(DefaultPlugins);
    #[cfg(debug_assertions)]
    {
        use bevy::diagnostic::FrameTimeDiagnosticsPlugin;
        app.add_plugins(FrameTimeDiagnosticsPlugin::default());
    }
    app.add_systems(Startup, setup);
    app.add_systems(Update, camera_movement);
    app.run();
}

[xbz-24]

and in setup():

fn setup(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
    mut materials: ResMut<Assets<StandardMaterial>>,
    mut meshes: ResMut<Assets<Mesh>>,
) {
    commands.spawn(Camera3dBundle {
        transform: Transform::from_xyz(3.0, 3.0, 3.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..std::default::Default::default()
    });

    commands.spawn(SceneBundle{
        scene: asset_server.load("gltf/scene.gltf#Scene0"),
        ..default()
    });

among other lines of code but this is the only ones that refer to the gltf

please help

also, when I try either exporting this, as glb or gltf (with the textures mapped) and I try to load that exported file with the asset_server

this is what I get

like only the fan gets rendered

at least with the correct textures tho

but only the fan out of the whole scene/mesh

[xbz-24]

also if I try to call for Scene1 instead of Scene0 I get this

this is the message from the console output: https://pastebin.com/m1xHr93u

[xbz-24]

please let me know how to put textures to this model

I am so close to actually mapping the textures but I am not sure how

please help

https://github.com/Xbz-24/Bevy-Sandbox.git

this is the code if needed.

[xbz-24]

please

can

someone

take a look

at why is

this

not mapping the textures properly?

[torsteingrindvik]

I cloned your repo and used this: https://gltf-viewer.donmccurdy.com/

I dropped the entire gltf folder into the validator such that it has access to all files.

The viewer shows the same as Bevy: The meshes are there but the textures are not attached.

I think it's more likely you are having Blender exporting issues than Bevy issues.

My advice then is to figure out the Blender side of things first, validate (with the one I linked or any GLTF validator) that things are working, then try it with Bevy.

but how do I do that without requiring of blender?
I want to do that through code, I was thinking maybe uisng a PbrBundle take as mesh the gltf model and using a standardmaterial of the aqua_diffuse.png as the material the entire #Scene0 from the .gltf needs to be mapped with the same png

[xbz-24]

I dont want to do it in blender, I know this model is not PBR so if I try to use a PBR bundle with the material as the texture of aqua_diffuse.png do you think i twill work?

[xbz-24]

thi is the content of my aqua_emissive.png
this is for aqua_diffuse.png

[xbz-24]

I am loading the emissive png using asset server
then I add it as a Standard material to my ResMut<Assets>
how do I use it though

pub fn setup(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
    mut materials: ResMut<Assets<StandardMaterial>>,
    mut meshes: ResMut<Assets<Mesh>>,
    mut window_query: Query<&mut Window, With<PrimaryWindow>>,
) {
    commands.spawn(Camera3dBundle {
        transform: Transform::from_xyz(3.0, 3.0, 3.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..std::default::Default::default()
    }).insert(Player::default());

    let emissive_texture_handle = asset_server.load("assets/gltf/textures/aqua_emissive.png");

    let emissive_material = materials.add(StandardMaterial {
        emissive_texture: Some(emissive_texture_handle.clone()),
        emissive: Color::WHITE, 
        ..default()
    });


    commands.spawn(SceneBundle{
        scene: asset_server.load("gltf/scene.gltf#Scene0"),
        ..default()
    });

for example SceneBundle does not receive a material
should I use a PbrBundle then?

if I use PbrBundle then it doesnt render at all anything
and it doesnt even say error log
look

pub fn setup(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
    mut materials: ResMut<Assets<StandardMaterial>>,
    mut meshes: ResMut<Assets<Mesh>>,
    mut window_query: Query<&mut Window, With<PrimaryWindow>>,
) {
    commands.spawn(Camera3dBundle {
        transform: Transform::from_xyz(3.0, 3.0, 3.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..std::default::Default::default()
    }).insert(Player::default());

    let emissive_texture_handle = asset_server.load("gltf/textures/aqua_emissive.png");

    let emissive_material = materials.add(StandardMaterial {
        emissive_texture: Some(emissive_texture_handle.clone()),
        emissive: Color::WHITE, 
        ..default()
    });


    commands.spawn(PbrBundle{
        mesh: asset_server.load("gltf/scene.gltf#Scene0"),
        material: emissive_material,
        ..default()
    });
