Brush Imbed and Depth
To offer a new way to create the brush which fits your needs, ZBrush now has a better control on the shape of the brush itself. By default, the brush of ZBrush is a sphere, which hemisphere is oriented to the surface, represented by the double disk cursor that you are familiar with.
With the new Brush Imbed and Brush Depth parameters located in the Brush palette, you can now change the shape of this sphere and flatten the top, the bottom of both sides, and even move up or down its center.
By flattening the top of the brush, only the parts which are on the same level of the hemisphere, or below, are affected by the stroke. If the brush is intersecting a surface which is in the upper hemisphere, nothing will happen.
Edit the following settings, located in the Brush >> Depth menu to change your brush behavior:
- Brush Imbed: this slider change the center of the Brush sphere by moving it up or down, the center is by default located on the top of the surface.
- Brush Depth: activate this option to enable the change of the outer and inner depth settings.
- OuterDepth: this slider lets you flatten the top of the brush sphere.
- InnerDepth: this slider lets you flatten bottom of the brush sphere.
- Brush Depth Curve: this curve will let you define the profile of the brush depth.
You can change these three slider settings by clicking on or by directly manipulate the widget. Three different settings with three different results.
Samples
- Buildup: When applying brushstrokes, information is constantly picked from the canvas and used to update the stroke.
- If Buildup is turned off, the current brushstroke is ignored while picking the information, until the mouse/pen button is released.
- If it’s turned on, the information is picked both from the canvas and from changes made by the current brushstroke.
- Samples Radius: ZBrush will sample the Normals and Position of the mesh under the cursor when being applied. If the settings are set at .75 then ZBrush is evaluating 75% of the mesh that is under the cursor.
- ConstSamples: Will keep the samples of the normals and position at a constant number based on the default brush size of ZBrush.
- OnSurface: This will keep the brush flat to surface when evaluating the curvature of a mesh. For example, if you apply the clay brush from the center to the outside of the polysphere with the OnSurface on and off you will see a smoother stroke around the sphere with OnSurface turned on.
- Preserve Edge: Will keep the edge of a mesh preserved when a brush comes into contact with an edge. This is a key setting when hard surface modeling.
- Stabilize Orientation: averages stroke normals. This will add stabilization to rough surfaces.
- Stabilize Direction: Will keep the surface normals stabile to the direction of the stroke. If you take the Clay Tubes brush along the Sphere with the setting at 100 you will see how the surface normal is following the stroke. This will also cause a slower reaction to the surface.
Modifiers
The Modifiers menu, located in the Brush palette, provides fine control over the brush itself and its shape. With the Tilt slider, set an angle to rotate your brush and create new sculpting effects. With this option, you will be able to sculpt the scales of a lizard easier than before.
The trails option, used by QuickSketch makes a connection between the beginning and the end of your stroke, by continuing it, depending of the option value.
- Tilt Brush: This will apply a tilt to the brush. If the slider is set to 35 then the tilt of the brush will be 35 degrees.
- ConstantTilt: This button will keep the tilt constant to the setting in the Tilt Brush slider.
- Trails: This slider will apply the selected brush bush multiple times depending on the setting. If the setting was at 50 then the brush will be applied 50x along the stroke.
As you move along the stroke the current brush will be applied 50 more times from the point of the brush cursor. If you set this setting relatively high you will see the stroke continue to grow even though your cursor is well past the point.
- Intensity: This will control the intensity of the trails.
Mask by Polygroups
Mask By Polygroup, located in the Brush >> Automasking menu, will apply virtual masking based upon the polygroups of the tool. If you have the setting at 100 then the first selected polygroup will be the only part of the mesh that can be edited by the selected brush. If you have the slider any lower then that it will allow multiple polygroups to be edited on a given stroke but with less intensity than the first selected polygroup.
Alpha and Texture
Vertical Aperture- This curve will control the vertical roll off of selected alpha. The selected alpha will be stretched to fit the selected brush size. This is a great way to create your own Radial Fade (Rf) that you fide in the Alpha Palette. Horizontal Aperture- This curve will control the horizontal roll off of selected alpha. The selected alpha will be stretched to fit the selected brush size. This is a great way to create your own Radial Fade (Rf) that you fade in the Alpha Palette. Polypainting modes
There are multiple polypaint modes available now when appling RGB to your tool. There are 5 modes which include, Standard, Colorize, Multiply, Lighten, and Darken.
Directional
The Directional mode and its associated curve, located in the Brush >> Automasking menu, makes the stroke and its associated alpha, following the path of your stroke while having a consistent draw to the mesh: if you choose a long and rectangle alpha, when doing a rounded stroke, the created shape will be smooth and not rotated.
Tablet Pressure : Use Global Settings
This mode, located in the Brush >> Tablet pressure menu lets you define the same tablet pressure settings for all your brushes, based on the setting set in the Preferences >> Tablet menu.
The Use Global settings option, in the Tablet Pressure menu.
