Collision Only being detected on one of the objects involved in the collision - C#

Hi all!

I have an object, an asteroid to be precise, which is set up with a Sphere Collider & a non-kinematic rigidbody.

The other object involved in the collision is your Player object, which has a bubble-shaped Shield as one of it's children, set up with a Capsule Collider.

The shield is where I'm calling the OnCollisionEnter function from.

The script is below:

  void OnCollisionEnter(Collision col) {
  
          Debug.Log(col.gameObject.name);
  
          if(col.gameObject.name == "Asteroid") {
  
              Debug.Log("HitAsteroid!");
  
          //    HitForce = col.rigidbody.mass/GetComponent<Rigidbody>().mass * GetComponent<Rigidbody>().velocity.z; - Ingore this for now, this is for the next part of the code, I just need to get the initial collision detection to work first!
          }
  
      }
  

The two objects physically collide with eachother, however the problem is, I don't get any feedback from collision, it just doesn't register it as a hit.

I have also tried putting this script on the other object as a test, and it works, it detects when it hits the player, but I cannot detect on the player when it hits an asteroid, it's weird.

So to sum up, both objects have a Collider (without Trigger enabled), and one of them has a Rigidbody. In theory this should work right, or am I missing something?

Thank you in advance :)
