How can I target specific meshes from a group gltf with ray caster?

let model = null
var children =

/**

  • Model
    */
    gltfLoader.load(
    ‘/resources/datacemetry.glb’,
    (gltf) =>
    {
    model = gltf.scene
    model.position.y=-19
    gltf.scene.traverse(function(child) {
    if(child.isMesh){
    children.push(child)
    }
    })
    scene.add(model)
    })

const tick = () =>
{
const elapsedTime = clock.getElapsedTime()

raycaster.setFromCamera(mouse, camera)

if(model){

    const stones= [children[2],children[3],children[4],children[5],children[6],children[7],children[8],children[9],children[10],children[11],children[12],children[13],children[14],children[15],children[16],children[17],children[18],children[19],children[20],children[21],children[22]]
    const intersects = raycaster.intersectObjects(stones)


    if(intersects.length)
    {
        stones.scale.set(1.2, 1.2, 1.2)
    }
    else
    {
        stones.scale.set(1, 1, 1)
    }
}




// Update controls
controls.update()

lerp.current = GSAP.utils.interpolate(
    lerp.current,
    lerp.target,
    lerp.ease
)

if (model) model.position.z = lerp.current
// Render
renderer.render(scene, camera)

// Call tick again on the next frame
window.requestAnimationFrame(tick)

}
