Grease Pencil Auto Interpolate
LAST UPDATED: October 2, 2026
2D Animation Made Effortless
Automatically generates smooth in-between frames while you focus on what matters most, your creative vision!
The Problem
You sketch perfect keyframes, hit play, and...choppy, jarring movement. Now begins the process of going through every layer, opening the interpolation tool, tweaking in-between settings for strokes, and repeating the process dozens of times for multiple strokes. What should take minutes can stretch into hours of tedious micro-management, especially when your drawings have a ton of individual stroke elements that all need their timing perfectly calibrated.
Draw & watch it flow
Powered by Grease Pencil Geometry Nodes, the addon works invisibly in the background, creating buttery-smooth interpolated animation with real-time playback processing.
