Inputs

Enables or disables contour lines drawn around the silhouette of an object.

External Line: Enabled	Disabled

Sets the color of external lines. This can also be driven by a texture.

External Line Color: Black	White	Pink and Blue	Textured

Controls the maximum thickness of the external lines. The Thickness parameter only accepts a constant value, to vary the thickness use the Thickness Modifier instead.

The thickness parameter is measured in pixels for a 1920x1080 resolution image, rendering in other resolutions rescales the thickness automatically so that it appears to have the same relative thickness at any resolution.

External Line Thickness: 0	3	8	15

Changes the width of the external lines, connect a texture here to vary the thickness along external lines. Lower values decrease the width of a line, with 0 resulting in no visible thickness, while higher values increase the width and a value of 1 results in full thickness. The maximum width of a line is always limited by the Thickness parameter, increase the overall thickness in order to give yourself more room for thickness variation.

Controls the opacity of external lines. Reducing the opacity reveals the base material underneath.

Opacity: 0	0.5	1

Enables or disables contour lines drawn along the prominent internal edges of an object. Use the Angle Threshold parameter to control which edges receive internal lines.

Internal Line: Enabled	Disabled

Sets the color of internal lines. This can also be driven by a texture.

Color: Black	White	Yellow and Pink	Textured

Controls the maximum thickness of the internal lines. The Thickness parameter only accepts a constant value, to vary the thickness use the Thickness Modifier instead.

The thickness parameter is measured in pixels for a 1920x1080 resolution image, rendering in other resolutions rescales the thickness automatically so that it appears to have the same relative thickness at any resolution.

Thickness: 0	2	4

Changes the width of the internal lines, connect a texture here to vary the thickness along internal lines. Lower values decrease the width of a line, with 0 resulting in no visible thickness, while higher values increase the width and a value of 1 results in full thickness. The maximum width of a line is always limited by the Thickness parameter, increase the overall thickness in order to give yourself more room for thickness variation.

Controls the opacity of internal lines. Reducing the opacity will reveal the base material underneath.

Opacity: 0	0.5	1

Controls the type of normal that is used for detecting internal edges.

When using Smooth Normal, by default, the shading normals are used which is commonly the best method as it will tend to capture the most prominent edges and detect edge breaks as long as the Angle Threshold is low enough.

When using Geometric Normals, the edges of each polygon are easily detected for line rendering. Using geometric normals can result in a wireframe style look at low Threshold values.

Normal Type: Smooth Normal	Geometric Normal

Controls when an internal line is detected and drawn based on the difference in angle between neighboring normals. Higher values result in fewer internal lines while lower values result in more lines. In general, it is recommended to start adjusting Angle Threshold to establish the main internal contours and then adjust Depth Threshold for additional control.

Controls how far apart two identically oriented faces can be in scene units before an edge is detected, this is based on z depth and the camera's angle. Higher values result in fewer edges being drawn because the faces need to be farther apart before edges can be detected. A value of 0 results in the internal lines covering the entire object. If you are already using a low Angle Threshold, changing this value may not result in much of a difference — balancing the two is important to finding the right look for your scene.
