Overview

Ink lines where the render's id, depth or normal passes step (silhouettes, creases, occlusions - exact, never fooled by a shadow) and hatching along the picture's flow in the dark tones, anchored to the surface. The engraving look over paper; luma_edges draws plates with no passes.

How to

How-to

Wire a render carrying id, depth and normal passes (a plate uses luma edges).
Turn on the edge sources you want and set their thresholds; thickness and pressure shape the line.
hatch adds tone-gated hatching on the painterly lattice; paper_colour and background set what the ink sits on.
Start from a preset (Engraving, Ink sketch, Contours only); ⚒ Bake frames when done.

Outputs

Output	Type
out	Image

Parameters

Parameter	Type	Default	What it does
id_edges	Float	1.0	Contours where the object id changes — silhouettes, exact.
depth_edges	Float	0.8	Contours where the depth steps — creases and occlusions.
normal_edges	Float	0.6	Contours where the normal turns hard.
luma_edges	Float	0.0	Contours from the picture's own luminance edges — for plates with no passes (fooled by shadows and texture, as any edge detector is).
depth_threshold	Float	0.04	A depth step counts when it exceeds this fraction of the depth.
normal_threshold	Float	0.3	A normal step counts when 1 − n·n′ exceeds this.
luma_threshold	Float	0.35	The luminance gradient that reads as a full-strength line.
thickness	Float	1.5	Line thickness, px.
pressure	Float	0.35	Pen-pressure variation along the line, seeded.
ink	Color	[0.02, 0.02, 0.03, 1.0]	Ink colour.
ink_opacity	Float	1.0	Ink opacity.
hatch	Choice	on	Hatching in the dark tones, along the picture's flow, anchored to the surface like the painterly strokes. `onoff`
hatch_level1	Float	0.35	Luminance below which hatching begins (one direction).
hatch_level2	Float	0.18	…below which it cross-hatches.
hatch_level3	Float	0.08	…below which it hatches densely (a third, diagonal family).
hatch_spacing	Float	6.0	Screen spacing of hatch lines, px.
hatch_length	Float	4.0	Hatch line length as a multiple of the spacing.
hatch_cell	Float	0.0	The hatching lattice's world cell size (0 = auto, reported — set it to lock the hatching to the surface across the shot).
hatch_angle	Float	0.0	Offset from the flow direction, degrees.
hatch_width	Float	1.2	Hatch line width, px.
grain_scale	Float	0.02	The paper / pressure grain's feature size in world units (with a position pass).
grain_scale_px	Float	6.0	…and in px without one.
paper_grain	Float	0.5	How much the paper's grain shows in the paper background.
baked	Text		The frames ⚒ Bake frames wrote; read instead of computed while set.
baked_hash	Text		The look fingerprint the bake was made from.
status	Text		What the node found in the stream — which passes drove the contours — and whether it plays from a ⚒ Bake.
background	Choice	paper	What the ink lands on: paper (a flat colour with grain), the plate, or transparency. `paperplatetransparent`
paper_colour	Color	[0.92, 0.9, 0.85, 1.0]	The paper's colour.
cadence	Choice	1	Stylize on ones, twos, threes or fours — the input is held at the stepped frame. `1234`
seed	Int	3	The random pattern's starting point. Change it for a different pattern of the same character; keep it to reproduce a frame exactly.
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
