Spacing Sculptor : Blender Animation Addon

Spacing Sculptor is a Blender addon which offers an interesting new approach to tweaking animation curves in the viewport.

It does not use “Editable Motion Paths”. Instead the workflow is as follows:

• you set your main keyframes/poses
• in-between the poses, you use a special offset mode that the addon provides to control the interpolation between the main poses. The offset is done in Blender’s 3d view.
• without adding new keyframes, this process tweaks the curves in the Graph Editor to achieve your desired motion, spacing and timing
