How To Use

At a simple level Pencil Pro is as easy as choosing a target collection and hitting a single button. However for artistic control and a more full understanding please watch this video:

Settings

Line Settings:

Collection (Collection): Objects to apply Pencil Pro to (must coincide with collection in lineart modifier).
Light Source (Object): Objects to apply Pencil Pro to (must coincide with collection in lineart modifier).
Light Threshold (Float): Threshold to delete lines facing light source.
Quality Level (Integer): Number of subdivisions to apply to source collection (for calculating edge flow).
Resolution (Integer): Resolution of pencil lines.
Duplicates (Integer): Amount of redraws of lineart.
Density (Float): How many pencil lines are spawned.
Length (Float): Length of pencil lines (reduce to fix floating lines).
Opacity (Float): Opacity of pencil lines.
Radius (Float): Thickness of pencil lines.
Radius Variation (Float): Changes thickness of distributed pencil lines.
Smooth (Integer): Fillets pencil lines to smooth out strokes.
Rotation Variation (Float): Randomizes 3D rotation of strokes.
Scale Variation (Float): Randomizes 3D scale of strokes.
Noise Strength (Float): Strength of distortion.
Noise Scale (Float): Frequency of distortion.
Noise Detail (Float): Detail of distortion.
Overshoot Probability (Float): Probability of extruding stroke endpoints.
Overshoot Strength (Float): Strength of endpoint extrusion.

Shader Settings:

Time (Frame): Used for randomization over time (by default set to #frame driver).
Aspect Ratio (Float): The aspect ratio of your camera/render (this is 1.778 for 1920x1080 for example).
Light Multiplier (Float): How much influence lights have on the shading.
Fresnel IOR (Float): Index of refraction for fresnel effect.
Fresnel Strength (Float): Strength of fresnel effect (used to highlight boundaries).
Roughness (Float): How much light diffuses across the surface.
Smudge (Float): A cosmetic effect to break up hatching/dots.
Dot Spacing (Float): Scale of dots in screen space.
Dot Threshold (Float): Radius of dots.
Dot Randomness (Float): Randomizes dot positions (use 0 for a perfect array).
Hatch Scale (Float): Scale of cross hatching in screen space.
Hatch Angle (Angle): Rotation of cross hatching in screen space.
Hatch Thickness (Float): Thickness of hatching lines.
Hatch Distortion (Float): Strength of screen space noise.

Installation

Install Pencil Pro just like any other addon (for Blender 4.3 or above). Drag the .zip right into Blender and hit ok. Menu can be found in the N-Panel of the 3D Viewport.
