## Opacity

These three tabs give you complete control over the color, thickness and opacity of lines. They enable you to create any type of line effect, from simple lines that fade out to complex brush effects. Each tab works in a similar way:

- Set the general color, thickness and opacity using the Color, Thickness and Opacity settings at the top of the tabs.
- Modify the color, thickness and opacity using the modifier options. To switch on a modifier, enable its option. You will see its settings appear in the bottom part of the tab, where you can adjust them.

### Opacity

Parameter ID: `OUTLINEMAT_OPACITY` · Range: [0..10000%]

Use this setting to define the overall opacity.

### Link to Thickness

Parameter ID: `OUTLINEMAT_OPACITY_LINKTHICKNESS`

The Opacity tab has a **Link To Thickness** option which enables you to use the same modifier settings for thickness and opacity. Instead of setting the modifiers on both tabs, set them on the Thickness tab only and enable the Link To Thickness option on the Opacity tab.

With a few exceptions, each tab has the same modifier options. For example, the **Along Stroke** modifier is present on all three tabs.

The **Distance** modifier modifies the color, thickness or opacity based on distance from the camera.

# Material Editor settings

### Strength

Parameter ID: `OUTLINEMAT_OPACITY_DISTANCE_STRENGTH` · Range: [0..10000%]

This is the strength of the modifier's effect, from 0% (no effect) to 100% (full effect).

### Range

Parameter ID: `OUTLINEMAT_OPACITY_DISTANCE_RANGE`

The **Range** setting defines the range over which the color, thickness or opacity is modified.

Object

This range is from the part of the object nearest the camera to the part furthest away.

Camera

This uses the camera's **Front Blur End** and **Rear Blur End** values (**Depth** tab) when you enable them. If the options are disabled then Sketch and Toon will use the **Target Distance** in place of **Rear Blur End** and the **Camera** in place of **Front Blur End**.

Custom

When you select the Custom range, you will see the **Min** and **Max** boxes appear. These define the start and end of the range as distances from the camera.

### Mode

Parameter ID: `OUTLINEMAT_OPACITY_DISTANCE_MODE`

> **Tip:** TIPNot all modifiers offer different modes from which to select.

A Distance modifier set to Linear mode in the Thickness tab. The graph controls the thickness of the line in relation to its distance from the camera.

Use this mode to define how thickness or opacity should influence a particular area. The Linear mode mixes line thickness or opacity evenly over a given area. The Invert option will reverse the direction of the mixing. If, on the other hand, you set Mode to Spline, a spline graph will appear in which you can draw a gradient that will influence thickness and opacity. The X axis represents the area from start to end of a given line, the Y axis represents its thickness or opacity.

### Invert

Parameter ID: `OUTLINEMAT_OPACITY_DISTANCE_MODE_INVERT`

- In the **Material Manager**, double-click the Sketch material to display its settings in the Material Editor.
- On the Thickness tab, set Thickness to, say, 30 pixels. On the Color tab, enable the **Along Stroke** option and define a gradient.

- On the Opacity tab, enable the **Texture** option and in the Texture settings that appear, click the Texture triangle and choose **Load Image**. Use the dialog that opens to load the chalk_chunky.jpg texture from Cinema 4D's library/pattern location.
- Set **Spacing** to 8% to form a continuous line of tiles (Figure 3, right line).
- The stroke looks too uniform. For a more natural effect, set the Variation value for Size to 20% and the Variation value for Angle to 10%. This varies the size and direction of the tiles (Figure 4, left line).

### Mapping

Parameter ID: `OUTLINEMAT_OPACITY_NOISE_MAPPING`

The Mapping drop-down list controls which coordinates are used to generate the noise. This can affect how the noise looks, how it changes as the object or camera moves and whether the noise is continuous over line segments if strokes are disabled.

Line 1D, Line 2D

![Image: 002989.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/002989.jpg)\
Strokes disabled (left) and enabled (right).

This modifier uses the position along the line. Avoid using this type if strokes are disabled, otherwise poor results are likely (see left cylinder above).

Screen

The noise is calculated in the space of the screen. The noise will change as the object's position on the screen changes.

Object

The noise is calculated in object space and remains the same regardless of object and camera moves.

World

The noise is calculated in world coordinates. The noise remains the same if you move the camera but changes if you move the object.

Controls the number of octaves over which the noise will span.

### Scale

### Detail

Parameter ID: `OUTLINEMAT_OPACITY_DETAIL` · Range: [0..+∞%]

Used for antialiasing. In general, leave the value set to the default of 100% but if the line texture flickers when you animate, try increasing the value. Or if you are rendering a high-res still and you want crisp detail, set the value lower.

### Low Clip

Parameter ID: `OUTLINEMAT_OPACITY_LOW_CLIP` · Range: [0..100%]

Use this setting to define lowest the point at which the noise will be cut off. All lesser values will be set to **0**.

### High Clip
