Hi:

I want to build a micraft like game; and when i render a face of block like this:

commands.spawn_bundle(PbrBundle {
        mesh: quad_handle.clone(),
        material: texture.forward.clone(),
        transform: get_transform_by_face_type_form_vec3(FaceType::Forward, vec3, cube_size),
        ..default()
    });

You can toggle the 'is_visible' bool in the 'Visibility' component that is part of the 'PbrBundle'
