Free Blender Add-on for converting mesh objects to Grease Pencil objects with edge filtering for sharp edges. It includes "Noise Modifier" for adding "wobble" and "variable line thickness" for cartoon effects. It also renders custom marked edges like "Marked Sharp", "Marked Crease" and "Marked Freestyle". It works with older Blender versions, from 2.81 and upwards.
