Modificador Arte Lineal

The Line Art modifier generates stylized line art from the scene or selected source collection or objects.

Nota

Due to lack of global cache at the moment, each Line Art modifier will run the entire occlusion calculation for itself. So if you have multiple line art modifiers to select different parts of the scene (to apply different styles, etc.), the evaluation will take much longer. There are plans to remedy this in the future, but this is a known limitation for now.

Opciones

El mofidicador Arte Lineal.

Source Type

What type of geometry source should line art be generated from.

Scene, Collection, Object

Source Selector

Based on the source type, collection or object can be selected as source geometry.

Nota

Line Art will still load and calculate the entire visible scene to produce correct occlusion result, unless specified to do otherwise in object or collection Line Art Usage property.

Edge Types

Line Art can identify different edge types. Selected edge types will be included in the result.

Contour

Where the edge becomes the separation line of front/backfacing faces.

Material Borders

Where the edge separates faces with different materials.

Bordes Marcados

Freestyle edge marks.

Intersecciones

Intersection lines between faces.

Plegar

Where the edge angle is small enough. Controlled by Crease Threshold property.

Crease Threshold

Edge angles that are smaller than this value will be treated as crease.

Target Layer

The Grease Pencil Capas to put the result in.

Target Material

The Grease Pencil Materiales to generate strokes with.

Remove Doubles

Perform an «merge by distance» operation when loading geometry into Line Art. The threshold of this operation is internally set to a value that is optimal for Line Art algorithm precision.

Overlapping Edges as Contour

This option allows overlapping edges (e.g. from an edge split modifier or imported geometry where two edges occupy the exact same space) to be drawn as contour. Enabling this option will slow down the calculation slightly but it will handle edge overlapping cases without erroneous occlusion results.

Instanced Objects

This option enables particles and other instanced objects to be loaded for line art calculation. There will be performance impact when there are a large amount of instanced objects in the scene.

Clipping Boundaries

When enabled, line art will generate clipping lines as contour type at the place where near or far clipping planes cut the model. Otherwise there will be no lines.

Style

Style subpanel.

Grosor

The strokes generated by line art are given this thickness.

Opacidad

The strokes generated by line art are given this Opacity.

Occlusion

Occlusion subpanel.

Rango

If enabled, the modifier will select lines that have an occlusion level between start and end values.

Level

Desired occlusion level to be selected as line art result. A value of 0 means visible lines (no occlusion). A value of 1 means selecting lines that have been occluded by exactly 1 layer of faces.

Transparency

If enabled, Line Art will only select lines that are occluded by certain faces whose material have specific occlusion masks set.

Masks

To select edges that have been occluded by selected masks.

Match All Masks

If enabled, only lines that are occluded with the exact transparency bit combination will be selected. Otherwise, lines that have been occluded by any one of specified transparency masks will be selected.

Demonstration of the usage of transparency masks.

Chaining

Chaining subpanel.

Chain Intersection with Contour

Allows intersection lines to be chained together with contour lines.

Nota

Enabling this option will lead to ambiguity in intersection edge types. Intersection lines that have not been able to chain with any nearby contour lines will remain as intersection lines.

Chain All Lines

Enabling this option will cause all lines to have the type of contour and to be chained together.

Umbral

Allow the end point of short segments to be chained together if the 2D image space distance between them are within the specified threshold.

Angle Splitting

Split a chain at sharp «turning» points specified by this angle.

Vertex Weight Transfer

Vertex Weight Transfer subpanel.

Filter Source

If source mesh has vertex groups whose name starts with this string, then the vertex weight info will be transferred into weight groups in Grease Pencil strokes.

Match Output

Transfer the filtered object vertex weights into Grease Pencil weight groups with the same names as the filtered ones.

Destino

If Match Output is off, then a target vertex group has to be specified. If there are multiple weight groups copied into target, then the highest weight value is copied into it.

Baking

Baking subpanel.

Bake Line Art

Bakes Line Art strokes for active Grease Pencil object within the start, end frame range in scene. Bake Line Art (All) bakes all Grease Pencil objects that contains at least one Line Art modifier. After baking, baked Line Art modifier will be deactivated automatically.

Clear Baked Line Art

Clears baked line art frames within the scene frame range for active Grease Pencil object. Clear Baked Line Art (All) applies the same operation for all Grease Pencil objects that contains at least one Line Art modifier.

Advertencia

If you have drawn anything manually in the frame range of where line art runs, this operation will also clear those strokes!

Continue without Clearing

Re-activate a specific Line Art modifier without clearing baked strokes. This is useful for working on multiple portions of frames separately.
