Somehow I’ve done something to my model that causes the Walk and Look around Tools not to work well. After positioning the camera, I can’t actually use the walk tool anymore, except occasionally it will let me take a couple of steps backward. If I’m in a wide open space on the model, I can still use it, but the moment I’m in a room, or near a structure (even outside a house, for example, but near an external wall), it will stop working. All I can do is rotate around.
The look around tool, then, will work, but I can see through everything. Not X-Ray mode, but when I spin around, if I’m close to a wall, instead of the way it used to work, as I spin around, I start seeing through the wall into adjacent rooms.
Are there settings I can change to affect this behavior? Thanks in advance for your help.
