Outlines

The Outlines node allows adding V-Ray Toon-like outlines to node materials. The Outlines node needs to be connected to the Outlines input of the Material node. You can then tweak the outlines' properties to your liking.

Line Color – Determines the color of the outlines. A texture can be attached to this input port.

Line Width – Determines the width of the outlines in pixels. The soft limit is 100. A texture can be attached to this input port.

Opacity – Determines how opaque the lines are. A texture can be attached to this input port.

Outer Overlap Threshold – Determines when outlines are created for overlapping parts of the object. Lower values reduce the outer overlapping lines, while higher values produce more overlapping outer lines.

Normal Threshold – Determines at what point lines are created for parts of the object with varying surface normals (for example, at the inside edges of a box). Lower values mean that only sharper normals generate an edge, while a value of 0.5 means that 90 degrees or larger angles generate internal lines. Higher values mean that smoother normals can also generate an edge. Don't set this value to pure 1.0, as this fills curved objects completely. 

Overlap Threshold – Determines when outlines are created for overlapping parts of the object. Lower values reduce the internal overlapping lines, while higher values produce more overlapping lines. Don't set this value to pure 1.0, as this fills the objects completely. 

Inner Line Control – When enabled, allows the inner line to be edited further. This option is disabled by default.

Inner Line Color – Determines the color of the inner lines. A texture can be attached to this input port.

Inner Line Width – Determines the width of the inner lines in pixels. A texture can be attached to this input port.
