I built some walls that normally don't have any collision on them so I had to put collision planes in front of them. This is okay for the player but when viewing in third person the camera passes through the walls like this:

And it also happens at the back of Hjerim House because the back does not have any collision:

The collision planes stop the player from passing through them but how do I stop the camera? This doesn't occur everywhere I've placed collision planes though - the camera bumps up against them as it should.
