I am trying to make a animation looking at a building facade. As the camera moves along the path it rotates or points the wrong way. How do I lock the view of the camera so that it continues to point in one direction and not rotate? Sorry if this has been asked before Cheers
Use [Track To] Constraint or perhaps secondly the [Locked Track] Constraint on the Camera. You can use this constraint as a complement to the camera moving along a path. Often you may use a third object to as a target to look at specific locations of another object. In the building example you could move any non rendered object to focus the track on floors or windows.
There are free video tutorials on the settings of these constraints on various websites. You can also experiment to determine the correct settings for you in a few minutes.
