# Additive Layer

> Documentation for Additive Layer.

## Description

**Additive Layer** has 2 main functions: weapon recoil and curve-based animations.

Curve-based animations are extracted from the **WeaponBoneAdditive** Game Object, which is animated by the *Animator Controller*:

<Tip>
  **Tip:** the demo project implements CurveEquip and CurveUnequip motions procedurally using this method. These animations only animate the WeaponBoneAdditive, so they do not affect other bones.
</Tip>

The procedural recoil is extracted from the [Recoil Animation](/scriptable-animation-system/recoil-system/recoil-animation) component.

* **Additive Bone**: an element used to extract the additive animation.

* **Interp Speed**: smoothing speed for curve animations.

* **Aiming Input Property**: float property which will scale down effect of curve animations.

* **Ads Scalar**: a multiplier which will scale down the curve animations influence when aiming. It is used to reduce procedural motion when aiming.
