Stone Wall

Stone Wall imitates rough-hewn stone masonry. You can control the width and profile of the mortar and the color of the stones. You can also create a three-dimensionally raised stone with a coarse or smooth surface.

## Control Descriptions

### Basic Tab

Stone Size

Zooms the selected surface in and out. Higher values zoom in, making the stones appear larger.

Surface Height

Adds three-dimensional height to the stones. High values extrude the surface. Low values yield a flat surface, like patio stones.

Left to right: Increasing Surface Height.

Stone Color

Selects the color of the stones. You can select a color using the eye dropper, the default color palette, or choose the foreground or background color. You can also choose one of the six most recently sampled colors.

Mortar Thickness

Controls the thickness of the cement between the stones. Higher values broaden the mortar. Mortar width scales with stone size.

Left to right: Increasing Mortar Thickness.

Mortar Color

Selects the color of the mortar.

Color Variation

Increases and decreases the brightness and hue of individual stones. Higher values widen the range of stone colors.

Left to right: Increasing Color Variation.

Edge Roughness

Adds a jagged edge to the perimeter of each stone. Higher values produce an increasingly uneven edge.

Grain

Adds subtle, organic noise—randomly placed blobs that add natural variation to the stone texture. Use only as much as needed.

Flat Mortar

Selecting this box produces a level surface. Clearing the box bevels the mortar. See Flat Mortar in the Brick Wall chapter.

Seamless Tile

Select this box to create a repeatable pattern with no seams.

Random Seed

Controls the random elements of this filter. Click it until you get a result you like.

### Lighting Tab

Direction

Controls the direction from which the light falls on your selection. Click and drag within the lighting control box to change the direction, or enter a value between 0 and 360 degrees.

Inclination

Controls the angle formed by the light and the page. Click and drag within the lighting control box to change the inclination, or enter a value between 0 and 90 degrees.

Highlight Brightness

Controls the intensity of the shiny highlights appearing on areas facing the light.

Highlight Size

Controls the size of the shiny highlights on areas facing the light; higher values yield larger highlights.

Highlight Color

Choose any color for the shiny highlights.

Light Boost

Strengthens the light source. High values yield a brighter light source. It’s like changing out a 40 watt bulb for a 100 watt bulb.
