Week 8 spline – facial performance animation

In this week, I convert my blocking to spline:

When I switched the animation to spline mode, I ran into some issues. I noticed that the character’s movements were too large and too fast, so I had to remove some keyframes. Otherwise, the character looked hyperactive—shaking back and forth while talking.

I did my best to adjust those key frames, but that led to a new problem: after reducing the rotation in the waist, the poses of the head and neck changed unexpectedly. Because of this, I had to go back and tweak each pose again to make sure everything stays accurate and flows smoothly.

I realized that I included too many expression changes during the blocking phase, which made the character’s face look overly busy. I’m hoping to get some feedback from George in this week’s review session to help me address the facial animation issues. When all the facial features are moving at once, it becomes hard to find a clear visual focal point. I think I should reduce some of the key frames for the eyebrows and mouth to create a stronger, more readable expression.
