base classes — bpy_struct, GpencilModifier

class bpy.types.BuildGpencilModifier(GpencilModifier)

Animate strokes appearing and disappearing

concurrent_time_alignment

How 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 strokes are being built

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

speed_factor

Multiply recorded drawing speed by a factor

Type:: float in [0, 100], default 1.2

speed_maxgap

The maximum gap between strokes in seconds

Type:: float in [0, 100], default 0.5

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)

time_mode

Use drawing speed, a number of frames, or a manual factor to build strokes

DRAWSPEED Natural Drawing Speed – Use recorded speed multiplied by a factor.
FRAMES Number of Frames – Set a fixed number of frames for all build animations.
PERCENTAGE Percentage Factor – Set a manual percentage to build.

Type:: enum in [‘DRAWSPEED’, ‘FRAMES’, ‘PERCENTAGE’], default ‘FRAMES’

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

classmethod bl_rna_get_subclass(id, default=None)

Parameters:: id (string) – The RNA type identifier.
Returns:: The RNA type or default when not found.
Return type:: bpy.types.Struct subclass

classmethod bl_rna_get_subclass_py(id, default=None)

Parameters:: id (string) – The RNA type identifier.
Returns:: The class or default when not found.
Return type:: type
