These buttons can be used if you want to archive brushes with individual settings for later use. Your brushes (as well as all other Cinema 4D presets) will be saved to a library in your user directory under MAXON/Version/library/browser/user.lib4d.
In the Content Browser you will find the presets (to download, delete, etc.) in the Presets/user/Sculpt Brush Preset directory.
The following commands are available in the Customize Commands Manager:
These only work if a Sculpt brush is active and can be accessed quickly via hotkeys.
Here you can define the size of the brush. This can also be done interactively in the Viewport by pressing
At the right is a second fx button that offers the 3D functionality of the Effector as you know it from BodyPaint 3D.
Here you can define if the region beneath the Grab brush should be moved in the direction of the mouse (Mouse) in the direction of the average Normals (Normals; most often perpendicular to the surface or to a specific axis of the coordinate system (X, Y, Z)).
Sometimes the Grab brush should not affect surfaces across its entire defined radius but should determine where its effect should end based on the underlying topology. This is what occurs when the Surface Distance option is enabled. As you can see at the center of the image above, the Grab brush normally affects surfaces across its entire radius, falling off towards the edge. Even the upper lip and the nose were pulled down slightly. On the head at the right on the other hand these regions remained unchanged because the brush’s effect was greatly reduced at distinctive edges or where the surface topology changed dramatically.
However, there is a disadvantage: the brush’s falloff effect is not uniformly round but square (see far right of image). This is more apparent for larger deformations.
