Generative Shape Fill, powered by Adobe Firefly, fills a selected shape with detailed vector graphics, guided by the shape's outline and an optional text prompt. It works on open and closed paths, basic shapes, grouped objects and compound paths, and can fill several shapes at once.
It first appeared in beta in Illustrator 28.6 in July 2024, powered by the latest Firefly Vector Model, and the April 2025 release, Illustrator 29.5, lists it as a new feature without the beta label.
What I did
- The problem: you draw a rough shape and Illustrator fills it with generated vector art. The generative model needs a mask, a clear inside region to fill. Rough sketches often have open paths, and an open path has no inside, so tracing the paths into a mask (a concave hull) broke down. That's where the open-path and clipped-fill failures came from.
- What we did: we trained a model that infers the region the user meant to fill from the rough sketch, whether its paths are open or closed. I brought it into Illustrator, so the fill now follows the shape you meant, not just the paths you drew.Rough outlineConcave hullOur model
Each row is one rough sketch: the mask a concave hull traces from its paths, then the mask our model infers. - The result: I led the quality work around it, which fixed open paths, poor shape adherence and clipped results, and improved background detection.
