class bpy.types.BuildGpencilModifier(GpencilModifier)

Animate strokes appearing and disappearing

concurrent_time_alignment

When should strokes start to appear/disappear

  • START Align Start – All strokes start at same time (i.e. short strokes finish earlier).

  • END Align End – All strokes end at same time (i.e. short strokes start later).

Type

enum in [‘START’, ‘END’], default ‘START’

fade_factor

Defines how much of the stroke is fading in/out

Type

float in [0, 1], default 0.0

fade_opacity_strength

How much strength fading applies on top of stroke opacity

Type

float in [0, 1], default 0.0

fade_thickness_strength

How much strength fading applies on top of stroke thickness

Type

float in [0, 1], default 0.0

frame_end

End Frame (when Restrict Frame Range is enabled)

Type

float in [-1.04857e+06, 1.04857e+06], default 125.0

frame_start

Start Frame (when Restrict Frame Range is enabled)

Type

float in [-1.04857e+06, 1.04857e+06], default 1.0

invert_layer_pass

Inverse filter

Type

boolean, default False

invert_layers

Inverse filter

Type

boolean, default False

layer

Layer name

Type

string, default “”, (never None)

layer_pass

Layer pass index

Type

int in [0, 100], default 0

length

Maximum number of frames that the build effect can run for (unless another GP keyframe occurs before this time has elapsed)

Type

float in [1, 1.04857e+06], default 100.0

mode

How many strokes are being animated at a time

  • SEQUENTIAL Sequential – Strokes appear/disappear one after the other, but only a single one changes at a time.

  • CONCURRENT Concurrent – Multiple strokes appear/disappear at once.

  • ADDITIVE Additive – Builds only new strokes (assuming ‘additive’ drawing).

Type

enum in [‘SEQUENTIAL’, ‘CONCURRENT’, ‘ADDITIVE’], default ‘SEQUENTIAL’

object

Object used as build starting position

Type

Object

percentage_factor

Defines how much of the stroke is visible

Type

float in [0, 1], default 0.0

start_delay

Number of frames after each GP keyframe before the modifier has any effect

Type

float in [0, 1.04857e+06], default 0.0

target_vertex_group

Output Vertex group

Type

string, default “”, (never None)

transition

How are strokes animated (i.e. are they appearing or disappearing)

  • GROW Grow – Show points in the order they occur in each stroke (e.g. for animating lines being drawn).

  • SHRINK Shrink – Hide points from the end of each stroke to the start (e.g. for animating lines being erased).

  • FADE Vanish – Hide points in the order they occur in each stroke (e.g. for animating ink fading or vanishing after getting drawn).

Type

enum in [‘GROW’, ‘SHRINK’, ‘FADE’], default ‘GROW’

use_fading

Fade out strokes instead of directly cutting off

Type

boolean, default False

use_percentage

Use a percentage factor to determine the visible points

Type

boolean, default False

use_restrict_frame_range

Only modify strokes during the specified frame range

Type

boolean, default False
