Stop-O-Motion is an animation tool designed to give standard 3D animations a frame-by-frame, stop motion appearance. It provides a dedicated panel in the Dope Sheet where users can apply various operations to selected keyframes to break up perfectly fluid interpolations.

The tool includes features for quantizing keyframes to fixed intervals like twos or threes, applying constant interpolation to eliminate blending between poses, and filling intermediate spaces. Additionally, it offers non-destructive workflows through a stepped modifier and a noise modifier to introduce subtle imperfections. Users can adjust modifier parameters such as frame range, blend in/out, and influence directly from the interface without needing to open the Graph Editor.
