On - enables or disables the VRayToon effect
Line color - this is the color of the outlines
Width Type - specifies weather the width of the lines will be measured in Pixels or in World units
Line Width - specifies the width of the outlines
Line Width Map - a multiplier texture for the outline width
Opacity - opacity of the outlines.
Compensate Camera Exposure - when enabled the VRayToon will compensate the Line Color brightness to adjust for any Exposure correction from a VRayPhysicalCamera
Opacity map - a texture for the outline opacity.
Hide Inner Edges - determines whether lines will be created for parts of the same object with varying surface normals (for example, at the inside edges of a box)
Normal threshold - this determines when lines will be created for parts of the same object with varying surface normals (for example, at the inside edges of a box). A value of 0.0 means that only 90 degrees or larger angles will generate internal lines. Higher values mean that more smooth normals can also generate an edge. Don't set this value to pure 1.0 as this will fill curved objects completely.
Overlap threshold - this determines when outlines will be created for overlapping parts of one and the same object. Lower values will reduce the internal overlapping lines, while higher values will produce more overlap lines. Don't set this value to pure 1.0 as this will fill curved objects completely.
Do reflections/refractions - this will cause the outlines to appear in reflections/refractions as well. Note that this may increase render times.
Trace bias - this parameter depends on the scale of your scene, it determines the ray bias when the outlines are traced in reflections/refractions.
Distortion Map - a texture that will be used to distort the outlines. This works similar to bump-mapping and will take the gradient of the texture as direction for distortion. Note that high output values may be required for larger distortion. Screen-mapped textures work best, although World XYZ mapping is also supported.
Result Affect - specifies a list of objects which will be affected by the VRayToon
As inclusive set - this option controls the meaning of the Result Affect option. When on the Result Affect is considered as an "Include list" and when off the the Result Affect is considered as "Exclude list"
