Reptile Skin

Reptile Skin simulates the scale patterns common to lizard and snake skin. Control the shape of the scales and whether they overlap. Apply Reptile Skin to photo color sources, patterns or solid colors. Create solid or tileable textures or apply Reptile Skin to any selection.

## Control Descriptions

### Basic Tab

Reptile Type

Selects one of the following scale options:

• Lizard—Yields non-overlapping scales.

• Snake—Yields overlapping scales.

Solid Color

Select this option to choose a single scale color. 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.

Color from Original

Select this option to color the texture using underlying color details.

Above right: Reptile Skin applied with the Color from Original option selected. Yes, that’s Animal Fur.

Feature Size

Zooms the selected surface in and out. High values yield a close up view of the texture with larger scales. Low values yield a distant view of the texture; scales become smaller and more densely packed.

Surface Height

Controls the bevelled elevation of the scales. Higher values increase the elevation.

Left to right: Increasing Surface Height.

Aspect Ratio

Manipulates the width of each scale. Increasing the value yields a wider scale.

Orientation

Rotates the texture. Use the circular slider or enter a value between 0 and 360 degrees.

Shrink Bumps

Controls the size of each scale. Low values yield scales that abut, forming hexagonal shapes. Higher values reduce the scales, creating scales divided by flat space.

Left to right: Increasing Shrink Bumps.

Flatten Bumps

Flattens the top of the scale. Higher values increase the size of the flattened surface.

Make Pointed

Controls the roundness of scales.

Left to right: Increasing Make Pointed values (Snake pattern).

Left to right: Increasing Make Pointed values (Lizard pattern).

Lighten/Darken Edges

Controls the darkness of the scale edges to mimic certain types of reptile scales.

Left to right: Increasing Lighten/Darken Edges.

Draw Outside Selection

Select this box to prevent scales from being cut flat at selection edges. Clear the box to cut scales off at the selection edge.

Left to right: Draw Outside Selection checked and deselected.

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.

### Distortion Tab

Distortion

Controls the uniformity of scale dimensions. Increasing values yield stretched scales of different sizes.

Left to right: Increasing Distortion.

Surface Roughness

Adds bumps to the surface of the scales. Higher values increase the apparent elevation and density of the bumps.

Add Bumps at Edges

Adds rough bumps to the edges of converging scales or the space surrounding scales.

### 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 45 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. You can select a color using the eye dropper or choose the foreground or background color. You can also choose one of the six most recently used colors.

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.
