The Interpolate tool creates an in-between keyframe by interpolating strokes between the previous and next Grease Pencil keyframes. When used on a frame between two keyframes, clicking and dragging will add a new breakdown keyframe, interpolating the stroke's shape based on the drag distance.

This allows artists to manually control how strokes evolve between poses or drawings, providing fine control over the interpolation result.

Note

When interpolating between curves of different types, a priority system determines which curve type is used. The priority from highest to lowest is: NURBS --> Bézier --> Catmull-Rom --> Polyline.

用法

  1. Place the timeline playhead between two existing Grease Pencil keyframes.

  2. In the 3D Viewport, click and drag left to right to set the desired interpolation factor.

  3. Release the mouse button to confirm and create a new breakdown keyframe.

The resulting keyframe contains strokes that are interpolated between the neighboring keyframes according to the chosen factor.

工具设置

层

Restrict interpolation to either the Active Layer or All Layers.

仅选中（编辑模式）

当此模式开启时，只有选中的笔画会被插值。

排除间断帧

Exclude existing Breakdown keyframes from being used as interpolation extremes.

翻转模式

Reverses the interpolation direction, swapping the start and end strokes. Automatic mode attempts to determine the correct direction for each stroke automatically.

平滑

The amount of smoothing applied to interpolated strokes to reduce jitter or visual noise.

迭代

The number of times smoothing is applied to newly created strokes. Higher values result in smoother interpolation but may reduce shape fidelity.
