A transition is the blending between a newly played motion (in transition) and previously playing motions (out transition). This process happens every time an animation is played or stopped.

In an effort to maximize the tool ease of use, transitions are reduced to only 2 variables:

• Time: The duration of the transition
• Easing: The easing function used to compute the layers weight over time.

FlexMotion allows to control transitions in 3 different ways:

• Via the FlexMotionAnimator default transition setting. The transition will be applied on every future animation played disregarding their avatar mask layer.
• Via the FlexMotion containers override transition setting.
• Via the FlexMotionLayer transition related settings like SetTransition. Modifying a transition this way is not persistent. As soon as another animation will be played the animator's default transition will be used again. Thus, it is typically set just after playing an animation via method chaining.

For example, this is how you would change the transition for a specific animation by script:

using System.Collections;
using SV.FlexMotion;
using SV.Utilities;
using UnityEngine;

public class PlaySpecificTransition : MonoBehaviour
{
    [SerializeField]
    private FlexMotionAnimator animator;

    [SerializeField]
    private FlexMotion flexMotion;

    private IEnumerator Start()
    {
        animator.defaultTransition.SetTime(0.8f);
        
        // Despite having set the default transition to 0.8 seconds
        // the transition will last 5 seconds due to having set a transition time
        // to the layer being played.
        animator.Play(flexMotion)
            .SetTransitionTime(5f)
            .SetTransitionEasing(Easing.Functions.CubicEaseOut);

        yield return new WaitForSeconds(6f);
        
        // Here the transition might also not be 0.8 seconds as I'm using a
        // FlexMotion container that can override the default transition.
        animator.Play(flexMotion);
    }
}
