Find all locations where a ray/ raycast insects an object

I am trying to raycast through a funky shaped object, and I want to find each intersection between my object an my ray.

So far as I can tell, Raycast returns only the RaycastHit closest to the ray origin, and Raycast all does the same for multiple objects.

Things I have tried: 1. A forwards and backward raycast captures entry and exit points from an object, but misses times where the ray exists and re-enters the same object. 2. A recursive solution would cast a new ray from each intersection, but there is no guarantee that the new ray will not re-hit the same point. In my hands, this is leading to a "StackOverflow" error.

Any help would be appreciated!
