# 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 ## Video Resources {% embed url="" %} --- # 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.
