    You must call CompositeShadowCaster2D.RegisterShadowCaster2D per each subtransform you add with a ShadowCaster2D.

    CompositeShadowCaster2D compositeShadow = source.transform.gameObject.GetComponent<CompositeShadowCaster2D>();
    if (compositeShadow == null)
    {
    compositeShadow = transform.gameObject.AddComponent<CompositeShadowCaster2D>();
    }

    compositeShadow.RegisterShadowCaster2D(shadow);

    Something like that must work.
