3D Onion Skinning v0.21.3

3D Onion Skinning is a Blender addon that visualizes animation spacing by displaying multiple frames simultaneously. This technique helps animators understand how their characters and objects move across successive frames, making it easier to identify spacing issues and refine motion quality. Version 0.21.3 provides the core functionality needed to overlay previous and subsequent frames in your viewport, giving you immediate visual feedback on your animation work.

The addon is essential for traditional animation workflows where onion skinning—viewing multiple frames at once—has long been a standard practice. By bringing this established animation technique into Blender, it allows you to evaluate frame-to-frame differences without switching between timeline views or manually toggling layer visibility. This streamlines the animation review process and helps ensure smooth, intentional movement throughout your sequences.
