# Brush

> **Note:** **What is it about?**
>
> This page documents the **Brush tool** in **Cinema 4D**, a modeling function for organically shaping meshes. It moves, smears or smooths all components within an adjustable radius — a lightweight alternative to the full Sculpting brushes for quick mesh adjustments.

The Brush tool works in all three modes (points, edges, polygons) and affects all points within the preview sphere defined by the radius.

You can use the Brush to shape existing polygon meshes in a variety of ways (although you have considerably more options with the [Sculpting Brushes](https://help.maxon.net/c4d/en-us/Content/html/49929.html.md)).

This tool has been available in Cinema 4D for some time now, allowing users to interactively and organically deform 3D meshes. Starting with version 2026.3, these functions can also be applied to UV points, edges, or polygons in the *UV Editor*.

The Brush works very similarly to the [Magnet](https://help.maxon.net/c4d/en-us/Content/html/TOOLMAGNET.html.md) and shares most of the settings with it. The fundamental difference (see [image](https://help.maxon.net/c4d/en-us/Content/html/TOOLMAGNET.html.md)):

- The **Magnet** is limited to the area on which you pressed the mouse button at the start.
- The **Brush** is always active where the cursor is when the mouse button is pressed.

The Brush radius is displayed with a spherical preview in the Viewport. Most painting modes require a Brush center point, to which the Brush draws attention with a dot that is also colored.

The deformation of meshes in particular opens up completely new possibilities for interactive modeling. You can now easily paint tentacles or other outgrowths on objects. Or, as in the above image on the right, give a figure a hollow back in Brush mode **.**

Make sure that your object is subdivided finely enough, as the Brush can only process existing points.

# How to use it

The Brush also works as follows: The more often you pass over a spot, the greater its influence. You can deactivate this effect by setting the **Strength** to **100%**, as the process will then be carried out like a mallet.

The following keys apply:

- `Ctrl/Cmd`: The effect will be reversed (more precisely, the **Strength** will be inverted).
- `Shift`: The mesh will be smoothed...
- `MMB` + mouse left/right adjusts the Brush size.
- `MMB` + mouse up/down adjusts the Brush hardness.
