To set up the scenario, I have a building with a hole, a passageway if you will, bigger than the character. At the moment, the character is a cube. The character has a rigidbody and box collider. The building has a mesh collider and a rigidbody. I want the character to be able to just casually walk into the building and look at what is inside it.
My problem is that there is a collider around the entire building so I cannot walk straight into the passageway. I want to be able to walk into the hole, but I cannot find a collider that I can only apply to the walls and not the passageway.
How can I fix this so the passageway exists, the building has a collider (so stuff cannot just walk through the walls), and so the character can walk into the building without a problem?
