How can I apply a texture loaded from a file to a UVSphere mesh?

[pfueyor]

I want to create several balls using shape::UVSphere. I've successfully rendered balls of different colors with a code similar to this one:

commands.spawn_bundle(PbrBundle {
        mesh: meshes.add(Mesh::from(shape::UVSphere { radius: 0.5, ..default() })),
        material: materials.add(Color::rgb(1.0, 1.0, 1.0).into()),
        ..default()
    });

These are solid balls painted with a single color each one. What I want to accomplish is to paint them with a custom texture loaded from a PNG file. How can this be done? Is it needed to use bevy::pbr::MaterialMeshBundle? Something like?:

commands.spawn_bundle(MaterialMeshBundle {
        material: materials.add(Material {
            color: Color::RED,
            color_texture: asset_server.load("some_image.png"),
        }),
        ..Default::default()
    });

Yeah. Such an example can be found in this example: https://github.com/nicopap/bevy_mod_paramap/blob/f2ecc42b79e9eb469485d79c7f2357fdf21f9fee/examples/earth3d.rs#L126-L159

This uses a custom material, but you can translate this to use the standard bevy material with:

    commands
        .spawn_bundle(PbrBundle {
            transform: Transform::from_rotation(Quat::from_euler(XYZ, -TAU / 4.0, 0.0, TAU / 2.0)),
            mesh: meshes.add(sphere),
            material: materials.add(StandardMaterial {
                base_color_texture: Some(asset_server.load("earth/base_color.jpg")),
                ..default()
            }),
            ..default()
        })

The default UV map seemingly uses an equirectangular projection.

It works! Thank you very much.
