> This page documents the **Abs node** of the Redshift renderer in **Cinema 4D**, one of its scalar math utilities. It outputs the absolute value of its input — handy for turning signed data like dot products into always-positive masks.

Returns the absolute value of *Input*. For example, a value of -1.0 will be returned as 1.0.
