I am integrating camera into our scene which is is a room-like setting and I would like the camera to be able to move all around the room boundaries which is basically the box. I want to have one of the camera modes that would use free camera to move all round the room but not get out of bounds. With another mode (orbit mode) I can just limit the zoom to/from the avatar to avoid getting out of the room. But with free camera I wanted to use the boundaries that com with Touch Camera but it seems only work with 2d shape, is it possible to extend it to 3d shape like box? Thanks!
