Use these settings to preview certain AOVs to aid in the development of your creative linework.


The Beauty AOV being rendered before the Stylized Looks filters are applied

Final Lines

View the output of the lines only.

Final Lines Invert

An inverted visualization of your lines

Final Lines + Beauty

This is the default visualizer and combines your linework with the beauty AOV

Final Lines Alpha

The alpha generated by the lines.

Line Thickness from Pattern

Visualize the thickness of your lines being generated from any patterns or textures plugged into the Line Thickness Input of your PxrStylized Control node.

Line Thickness from Lighting

Visualize the line thickness generated from the scene lighting

Diffuse Luminance

The luminance of the diffuse AOV

Diffuse Energy

The energy emitted by the Diffuse AOV

Z CamDist

Use this selection to visualize your CamDist 

Light Signal AOV

The name of a color AOV to do line detection on. 

Typically this would be diffuse, but you can also put a light AOV here to determine the transition between photoreal and stylized based on the light emission.  This AOV has to be set up in Maya/Katana/Houdini or DisplayFilter will exit.

Diffuse Energy From

Under the hood a white shader approximation is created based off the Signal AOV to drive the Hatching. By default using average of RGB components of Signal AOV, but can also divide Signal AOV lighting results with a pure albedo from NPRalbedo AOV or albedo AOV. If NPRalbedo AOV chosen, must set Albedo Color in Stylized Controller Pattern node.

Light Mask Switch

Use light aov defined in signal_aov_string above as mask for previously daisy-chained Stylized shaders and/or physically based lighting

Line Type

aov - custom AOV defined below
outline - line on alpha of object
sections - line on random id
lineNZ - line on combination of X Y components of surface normal and Z depth, good for unit scale
curvature - line on change in surface normal
camdist - line on change in camera distance

Final Line Gamma

After line detection happens, runs gamma on final lines.  When using the Curvature Line Type, you can use this parameter to control the curvature falloff to fine-tune your linework

Weight Type

During line detection weighting to get a variance

Different weight types graph:

Sigmoid Sharpness

See: and modify sharpness variable "a"

Sigmoid Offset

 See: and modify offset variable "o"

Activation Function

During line detection weighting to get a variance

Line Thickness From

Determine how to calculate the line thickness

Line Thickness

The thickness of the lines

Line Thickness Scale

Globally scale line thickness. If you have line thickness set per object and they are all different values, and you up the resolution of the render, use this global scale to increase or decrease line thickness of all lines, since they are based on pixel width.

Line Color From

Offers a number of different functions to determine line color

Use Line Mask

Mult by line mask from pattern node in AOV NPRlineMask

Lines Inside

Mult by alpha for only inside lines from line detect, don't go off geo

Light Response

Color lines by lighting
