Hello.

I have a problem in keeping the main camera locked into position form areas in my scene that I have passed by.  For example, I have a room where I move the camera starting from the left side of the room facing the left wall and gradually I move the camera through the whoe room facing each subsequent wall.  While I am moving the camera everything looks perfectly aligned as far as it facing the correct wall and items I have on that wall.  I place keyframes at various points as the camera travels and on the turns it makes to the other walls.  All looks good while I am making the animation from one wall to the next. 

However, by the time I get to the 3rd wall, if I back track I find that where the camera once looked perfectly position it is no longer correct. Its as though somewhere along the path I created, something causes the path of where the camera was earlier to change and no longer view that part of the room correctly. Is there a way to lock the camera for paths I created so that they don't change by something I am doing farther down the animation path? In my case, when I saw the left wall looking perfect, how can I lock that path along the left wall before I turn the camera the the next wall so that the left wall travel path continues to look as I saw it originally?

 

Not sure it was the best solution but decided to make the camera linked to a small object that I move around the room.  That seemed to reduce some of the problems I had earlier. At least this way its not as easy to mistakenly move one of the camera movement points.
