# Base Modifiers

Base modifiers are alterations that change an animation as a whole, rather than at a specific moment within it.

### What they have in common

Every base modifier acts on the entire performer. Switching one on changes the whole animation. Each one meaningfully alters the result.

Base modifiers can also be saved together with a style as a single **Preset**. A Preset captures a style plus the modifiers applied to it, so a look you've dialled in once becomes a cohesive custom style you can reuse.

### What's included

* **Loop** - creates looping animation from the provided root motion.
* **Mirror** - mirrors the animation left-to-right.
* [**Key Idle Pose**](/learn/concepts/motion-stage/key-idle-pose-kip.md) - defines the pose the character reaches when coming to a stop, or accelerates from, at idle.
* **Phase-Shift** - shifts the gait phase, changing which foot hits the ground throughout.
* **Character Scale** - scales the character and provides believable results at different heights while keeping root motion the same.

### What isn't a base modifier

* **Cues** directs a performance at a specific point across time while a base modifier applies across the whole performer.
* **Styles** are the underlying movement character. Base modifiers alter a style; they don't replace or become one.

### When to reach for a base modifier

Reach for one when the thing you want to change is true of the entire animation - it should loop, it should face the other way, the character is a different size. If you want something to happen at a particular moment, that's a cue. If the movement itself is wrong, change the style rather than modifying it.
