# 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*:

{% hint style="success" %} **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. {% endhint %} The procedural recoil is extracted from the [Recoil Animation](/scriptable-animation-system/recoil-system/recoil-animation.md) component. ## Properties

* **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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
