# Volume Scalar Attribute

> **Note:** **What is it about?**
>
> This page covers the **Volume Scalar Attribute node** of the Redshift renderer in **Cinema 4D**. It reads scalar volume grids — density, temperature — for programmable volume shading, including noise-based detail enhancement.

The *Volume Scalar Attribute* is a shading node that allows for programmable volume shading when used with a [Standard Volume shader](https://help.maxon.net/c4d/en-us/Content/html/COM_REDSHIFT3D_REDSHIFT4C4D_NODES_CORE_STANDARDVOLUME.html.md). For example, a VDB grid can be loaded and it can be displaced with a noise shader. This can be used for many creative effects and adding detail to low resolution volumes.

This node has no effect when not used with a [Standard Volume shader](https://help.maxon.net/c4d/en-us/Content/html/COM_REDSHIFT3D_REDSHIFT4C4D_NODES_CORE_STANDARDVOLUME.html.md).

## Example Graph

In the example below, a Volume Scalar Attribute node is used to load a density channel and directly drive the density input on a [Standard Volume shader](https://help.maxon.net/c4d/en-us/Content/html/COM_REDSHIFT3D_REDSHIFT4C4D_NODES_CORE_STANDARDVOLUME.html.md). This density channel is displaced by three Maxon noises, each uses the same noise type but with a different seed — this ensures that the volume is adequately displaced in 3D space. The three noises are fed into a vector maker which is then fed into a *Vector Change Range*. The *Vector Change Range* has the Output Min and Max on all three axes set to -1 to +1, this centers the displacement on the volumes axis. After this, a vector multiply node is used to control the intensity of displacement on each axis.
