From the default smooth curve it gives, I usually would like to change it to either ease in or out. However changing the curve has to be done per axis of the vector even when selected together. How to change them all together so that their curve ended up exactly the same? Other than having to line it up manually? I have been doing this for 4-5 years, I guess it is about time to ask Also how to preview only once and not having it loops like crazy, other than having to add a dummy far away keyframe that I always forgot to remove?
