Grease Pencil 2D Morphs

Addon for Blender that uses Grease Pencil frames made by the user to make interpolated frames and a rig control to manipulate the frames in order to fake shape keys in up to two dimensions. Could be useful for rigs with head turns, muscle bulging, automatic jiggle physics, and probably more. In order to morph things that should be animated separately such as eyes and mouths, the addon also features bone morphing with the same controls.

Interpolate Sequence Disorderly

The addon also comes with a custom Grease Pencil operator "Interpolate Sequence Disorderly" that does the same thing as Interpolate Sequence, but can handle interpolating between two frames whose stroke orders are different. See the introduction video for limitations.

Current version is 1.2 for Blender 4.0.1
