The Line Art modifier generates Grease Pencil strokes automatically from your 3D geometry. Aim it at the environment you built on Days 2–3 and you get a drawn version of it — one that updates when you change the model.
- See what it finds, and what it misses
Try it on your character too. Line Art detects silhouettes, creases and intersections, and it is good at the first two. Where it misses is instructive: it cannot know which lines matter, only which ones geometrically exist.
That gap — between the lines that are there and the lines a person would draw — is most of what makes drawing a skill.
- Look at where it leads
This is the doorway to stylised and toon-shaded looks, and half an hour is enough to know it exists and roughly what it can do. Chasing a finished stylised render is a much longer project than this track.
Grease Pencil does not travel into a game engine as drawn strokes. Its outputs here are rendered images and image sequences. There is no export that lands these lines in Unreal as lines.
Its real value to you is as a thinking and planning tool — which is how professional animators use drawing anyway. Knowing that now saves you a frustrating afternoon later, hunting for an exporter that does not exist.
That is the track
Two hours or so, entirely optional, nothing graded. If one thing survives from it, make it GP3: planning motion by drawing it is a habit that will keep paying off long after you have forgotten which menu Line Art lives in.
- Line Art is running on one of your own models.
- You can name one line it found and one a person would draw that it missed.
- You know Grease Pencil's output is images, not engine geometry.
