Timeline Mixer provides three operating modes that define how timelines are evaluated and blended.

Each mode controls:

How many timelines may be active simultaneously
Whether animation balancing is applied

Mode	Multiple Active Timelines	Animation Balancing	Intended Use
Multiple	Yes	Enabled	Layered blending or general sequencing
Solo	No	Enabled	State-style switching
Animation Unsafe	Yes	Disabled	Advanced / debugging use

The “Intended Use” column reflects common usage patterns, not strict limitations. Modes may be used in any workflow that fits your design.

Multiple Mode

Allows multiple timelines to be active and blended simultaneously. If animation tracks target the same object, Timeline Mixer automatically balances animation weights to prevent conflicts.

Solo Mode

Ensures that only one timeline remains active at a time.

Calling FadeIn on a timeline automatically triggers FadeOut on all other active timelines.

Animation Unsafe Mode

Allows multiple timelines to be active, but disables animation balancing.

When multiple animation tracks target the same object, no automatic weight correction is applied. This may result in unexpected and unpredictable blending behavior.

This mode is not exposed in the standard inspector and is intended for advanced or diagnostic use.

It can be accessed from the debug mode inspector, or by calling:

timelineMixerComponent.SetMode(
    TimelineMixerBase.Mode.AnimationUnsafe
);
