RigSketch Puts a Skeleton Under Every Drawing

Field notes

The workflow uses a poseable 3D reference as an underlay: users choose a clip, scrub to a frame, draw over it, and step forward while the previous drawing remains visible as a ghost. The package lists 28 rigged models and about 340 clips, including animals, robots, a dragon, and human figures. It also accepts imported glTF or FBX characters and animation files, then exports PNG sequences, sprite sheets, GIF, MP4, or WebM. The page names Windows 10 and 11 as supported systems and recommends a pressure-sensitive stylus.
