Animation playback speed not being respected
Hello. I work with Live2D SDK for Unity. It came to my attention that the animation playback speed isn't being respected for the following code when fading between animation clips:
When fading ends, animation speed works as intended, but at the end, parameters also snap between values, resulting in jerky movements.
The issue only occurs when switching between different animations with fading. When there's no fading, animation speed always works as intended.
Video example
Thank you for your time.
motionController.PlayAnimation(clip, layer, prio, looping, SPEED);When fading ends, animation speed works as intended, but at the end, parameters also snap between values, resulting in jerky movements.

Thank you for always using our products.
The motionController.PlayAnimation() method in the Cubism SDK for Unity does not currently support playback speed control.
Best regards.
MotionController.PlayAnimation() does have a speed param, so I'm a bit confused. I suppose it just doesn't work as intended in certain situations (with fades in particular)? Is there a particular way you'd recommend to control the playback speed, with the Animator approach for example? Are there plans to solve the issue in the upcoming updates, perhaps?
Thank you
animator.Play(state, 0);animator.speed = 0.2f;Are there plans to address the issue? Changing playback speed is rudimentary functionality for animation software, so it's a little puzzling that it doesn't work, to be honest. I can think of hundreds of different scenarios where it would be useful in a Unity project, whether it's a game with different spell effects (freezing effect, which slows animations down, for example), VTubing software, or anything else. I'd really appreciate it if you could share your thoughts on this.
Thank you.
The Cubism SDK for Unity includes a feature that smooths transitions between playing animations, but this feature does not support playback speed control.
If you want to control the playback speed of a Cubism model’s animations in Unity, please remove the `CubismFadeController` from the model’s Prefab and play the animations using the Animator.
We will share your request for playback speed control with the development team.
Best regards.
