# Is Included

> **Note:** **What is it about?**
>
> This page covers the newer **Is Included node** variant of the Scene Nodes system in **Cinema 4D**. It tests whether a value exists in an array, outputting a boolean plus the matching indices — content-based lookup.

This node outputs a simple bool signal, depending on whether a certain value is present in the linked array (*true*) or not (*false*). You can also read out the indices of all values found and the smallest index number at which the value can be found.
