Excuse my ignorance.
I have an objects Loc keyframed on frame 0, I advance the frameslider to frame 10, add a new object to the scene and key frame its location. if I play back the animation, both objects are to be seen from from 0, very startling for me.
I too a look in the dope sheet view and graph vie, the keys for the second object were placed on 10
Why is the image then to be seen all the time, from from 0?
