# FadeFromTo Action

## Overview

![The FadeFromTo Action Node.](/files/bviVd3ESNcmUELVRNHwR)

The **FadeFromTo Action Node** continuously modifies the `Opacity` of an **Object** over a specified period of time, thus creating an **Animation**. Both the initial and final values of the `Opacity` are chosen by the user.

[**Scope**](/incari-studio/2022.1/toolbox/overview.md#scopes): **Scene**, **Function**, **Prefab**.
