This patch adds two options:
- Convert a mesh to grease pencil strokes.
- Bake the mesh animation into grease pencil strokes.
Both are related and must be included in the same patch.
Related to tasks: T77629 and T77630
Notice: The conversion is done for mesh edges and it's not considering any visibility clipping. All edges are exported, no matters if it's visible or not.
Example of Convert a Mesh to Grease Pencil strokes:
{F8606028}
This conversion was inspired by the technique used by @luamono in this tweet: https://twitter.com/luamono/status/1239983662176841730
Example of Bake Animation (the video is a little outdate, but the basic functionality is the same, only small changes in UI):
