Basic Collider Query

I don’t get it. My collider (which isn’t a trigger) is large enough not to go through an object (that also has a collider that isn’t a trigger). It then goes through said object. I’m not entirely sure why this is happening.

I am using the stock FPS controller in Standard Assets as something to test with, maybe there’s something relating to the Character Controller. The Rigidbody Standard Asset doesn’t have this problem.

Could someone please advise on why this is taking place? Below is a quick video of my scene showing that the collider goes through another collider. The Character Controller however does not go through the collider of the other prefab.

Make sure that the layers your objects are on are set to collide with each other in the Physics settings.
