Stroke palette
The Stroke palette

The Stroke palette provides a variety of stroke types which determine how each brush is applied when the cursor is dragged on the model. By default, most brushes are applied with the Dots or Freehand stroke selected — these produce lines which follow the cursor drag.

Stroke type selection slider

Strokes can be selected by their numerical ID using this slider.

Current Stroke thumbnail

The large thumbnail displays the selected Stroke. Clicking the thumbnail will show a pop-up window for choosing a different stroke.

Mouse Avg

Mouse Input Average Count. The Mouse Average slider affects the way cursor input is processed by ZBrushCore. A value of 1 means the actual mouse position is used at all times. A value of 2 or higher means a number of mouse positions are read and averaged before arriving at a final value. This can result in smoother drawing movement.

Stroke Jitter

Stroke >> Jitter will randomly place the alpha along the brush stroke path. The higher the value the more variation will be applied.

Brush Imperfection

Stroke >> Imperfections will introduce what is essentially noise along the brush stroke. The higher the slider value the greater the number of imperfections.



The Replay Last button re-traces the last brush stroke (from mouse/pen click to release), regardless of whether it was created using the same tool or settings.


The Replay Last Relative button will replay the last brush stroke at the new cursor position, as long as the mesh has not been rotated. The hotkey Shift+1 must be used as the start is dependent on the cursor position. (The button is provided so a new hotkey can be assigned if desired.)


Sculptris Pro

When the Sculptris Pro button is enabled all brushes that are compatible with Sculptris Pro mode will add triangle tesselation with each brush stroke. This mode will also deciamte where needed as the brush is applied to the surface.

Adaptive Size

When the Adaptive Size button is activated the Draw Size will control the amount of tesselation being added with each brush stroke. This ia a global setting that will affect all brushes that can use Sculptris Pro mode.

With the Adaptive Size button activated, a larger Draw Size will add less tesselation and a smaller Draw Size will add more tesselation.


When the Combined button is activated, each brush stroke will add tesselation relative to the SubDivide Size slider and decimate relative to the UnDivide Ratio slider.

If the Combined button is not activated then each brush stroke will only add tesselation.

This is a global setting that will affect all brushes that can use Sculptris Pro mode.

SubDivide Size

The SubDivide Size slider controls the degree of tesselation that will be added to the mesh when applying a brush stroke. A lower setting will add more small triangles; a higher setting will add fewer and larger triangles.

This is a global setting that will affect all brushes that can use Sculptris Pro mode.

UnDivide Ratio

The UnDivide Ratio slider controls the amount of decimation that will be applied with each brush stroke. A higher setting will add larger triangles. This is especially noticeable when smoothing the mesh when Sculptris Pro mode is activated.

This is a global setting that will affect all brushes that can use Sculptris Pro mode.


Lazy Mouse


When LazyMouse is on, drawing will take place not under the mouse cursor, but under a brush point that is being ‘dragged behind’ the mouse cursor by a virtual string (shown onscreen as a red line.) This allows for very precise control of the brush point, and is ideal for drawing smooth, predictable curves, or any sort of detail work.


Steps Relative To Brush Size. When the Relative button is on the LazyMouse stepping will be set by the brush size.


Allows lazy mousing to be applied in discrete steps. As you pull the brush around, the brush effect will be applied at intervals determined by LazyStep.


LazySmooth makes the lazy mouse effect stronger or weaker.


When the LazyMouse feature is on, LazyRadius sets the length of the ‘string’ connecting the mouse cursor to the drawing point. The longer the string, the more precise the stroke, but the further you’ll have to move your hand to make it.


LazySnap makes the lazy mouse snap to the model.
