# Falloff

## Description

Falloff is a complex tool that allows you to affect property values based on the position of a "falloff controller"

## Setup

1. Select all layers you would like to affect with the falloff controller. With all layers selected, now select one or more properties on **a single layer** that you would like affected across all layers. E.g., if you want to affect Opacity and Position, you should only select those properties on a single layer. If you select them across all layers, a new effect control will be created for each one of the layers, rather than a master control that affects all at once.
2. Run Falloff, and modify the corresponding effect controls

{% hint style="info" %}
You can add new properties to an existing Falloff controller by also selecting the Falloff control layer before running the tool
{% endhint %}

## Effect Controls

### Master

**Enable**\
Enables falloff

**Invert**\
Invert the affected property values when in the falloff zone

**Falloff**\
Changes the radius of the inner circle on the falloff controller. By doing this, it changes the "smoothness" by which the falloff controller changes the intended property values. 

### Falloff - Property Control

**X Amount**\
Affects the first dimension property value of the intended property

**Y Amount**\
Affects the second dimension property value of the intended property

**Z Amount**\
Affects the third dimension property value of the intended property
