How important graph editor is ??
For 3D animator, sometime or may be more, think about Graph editor, which means animation curves.
For me, It was more important things. I struggled every time.... add keys on curve and delete them..
I believed it is the best method for me at that time.
But now, I'm not using Graph editor a lot. I know that curve represent movement, but I notice that most important things is "Silhouette", In other word "Posing".
Good "Posing" represents lots of things for audiences.
In my point of view, good "Posing" is more important than smooth movement.
If you make good "Posing" at each frame, It makes definitely smooth movement.
I do not deny importance of curves but I notice power of "Posing".
Just one "Pose" but It represent a lots......
