How can I make the ray ignore an object without using a layer?

Answer 1

Physics.RaycastAll() - get an array of hits of all objects that the ray "pierces", select the desired collider from the array, for example, by tag

RaycastHit[] hits;
hits = Physics.RaycastAll(transform.position, transform.forward, 100.0F);
