So can you still move if you click through the walls? (IE. Your camera is outside the wall, while you are in)
Sorry for slow response. Tried to answer earlier on my laptop, but it was having issues and it wasn't worth fighting with it for one post.
So long as you aren't directly beside the wall, with a low camera angle, or have the camera near parallel to the floor, then you should be able to click and move around easily, despite the wall.
The wall can not be gone through however, it is still a solid object. This merely makes it easy to find your boundaries while not having to worry too much about the walls interfering with your vision.
