How to mix track in Unity

KLCL

Hi, I am trying to Additively mix tracks and make a breathing effect.
It's easily done in Spine by pressing the green plus button (see image).

The question is, what code should I use in Unity?
Somehow I cannot get them to function the same way as in Spine.
The working animation becomes distorted when I export them to Unity.
Any help would be appreciated.

I see nothing obviously wrong with your code. In general, when setting the first animation on track 13, you would usually call SetAnimation(13, _breathe, true) instead of AddAnimation(), but anyway this should not create distorted animation.

Could you please show us a video or screenshots showing in which way your animation gets distorted?
