The Build modifier make strokes appear or disappear in a frame range to create the effect of animating lines being drawn or erased.
This documentation refers to the Build Modifier specific to the Grease Pencil object. For uses with other object types refer to the general Build Modifier.
Determines how many strokes are being animated at a time.
Strokes appear/disappear one after the other, but only a single one changes at a time.
Multiple stroke appear/disappear at a time.
Builds only the strokes that are new compared to last keyframe. The assumption is Additive Drawing was used so that the shared strokes are the same.
- Transition (in Sequential and Concurrent Mode)
Determines the animation type to build the strokes.
Shows points in the order they occur in each stroke, from first to last stroke. (Simulating lines being drawn.)
Hide points from the end of each stroke to the start, from last to first stroke. (Simulating lines being erased.)
Hide points in the order they occur in each stroke, from first to last stroke. (Simulating ink fading or vanishing after getting drawn.)
The way you want to time the building of the strokes.
- Natural Drawing Speed (in Sequential and Additive Mode)
Use the recorded speed of the stylus when the strokes were drawn.
- Factor de Velocidad
The recorded speed is multiplied by this value.
- Maximum Gap
The maximum gap between strokes in seconds.
- Number of Frames
Set a fixed maximum number of frames for the build animation. (Unless another Grease Pencil keyframe occurs before this time has elapsed.)
The maximum number of frames used.
Number of frames after each Grease Pencil keyframe before the modifier has any effects.
- Percentage Factor
Manually set a percentage factor to control the amount of the strokes that are visible.
The factor from 0 to 1.
- Time Alignment (in Concurrent Mode)
- Align Start
All stroke start at the same time (i.e. shorter strokes finish earlier).
- Align End
All stroke end at the same time (i.e. shorter strokes start later).
Use the distance to an object to define the order in which strokes appear.
If enabled, only modify strokes during the specified frame range.
- Inicio, Fin
Determines the start and end frame for the build effect.
Defines how much the stroke is fading in/out.
How much strength fading is applied to the stroke’s thickness.
How much strength fading applies to the stroke’s opacity.
- Weight Output
Assign a weight value to points that have started/finished the fade.
