Learn how to use Generative Shape Fill to add detailed vector graphics to shapes.

Generative Shape Fill, powered by Adobe Firefly, lets you fill shapes with detail and color in your own style.

Try it yourself
Follow along with a sample file to learn how to quickly generate a shape fill.

Generate unique fills guided by the outlines of shapes and optional text prompts.

Use the Selection   tool to select the shape you want to fill with vector graphics.

You can use shapes such as open and closed paths, basic shapes, grouped objects, and compound paths. You can also select multiple shapes.

In the Contextual Task Bar that appears, select Gen Shape Fill   .

You can also access this feature from Object > Generative, the Quick Actions section of the Properties panel, the Gen Shape Fill   icon in the Control panel, and the right-click menu.

In the prompt field, describe the fill you want to generate. The prompt is optional, but without it, the fill will be based entirely on the outline of the shape.

If you don’t want prompt suggestions, select View all settings   , and then toggle off Suggestions.

Use the options in Shape strength and detail   as needed:

  • Shape Strength: Move the slider to adjust how closely the fill must match the shape's outline. When set to High, the fill will fully match the outline. When set to Low, the fill will have contours closer to that of real-life objects without always fully matching the outline.
  • Detail: Move the slider to adjust the level of detail required in the fill.

Use the options in Style Reference   as needed:

  • Style reference: Leave Auto enabled if you want the style of the fill to match the style of the objects (vector or image) surrounding the selected shape. To pick a style from a specific object in your artwork, select Choose asset or Replace asset. Then, either select the object or draw a lasso around it.
  • Effects: Apply one or more preset effects. Select Clear all to remove the effects.

Select Clear all next to Styles to remove the style reference and the effects.

To refine the colors, select View all settings   . In the Gen Shape Fill dialog box that opens, select Color and Tone:

  • Color Presets: Apply a color preset.
  • No. of colors: Leave it as Auto or set the number of colors you want in the fill.
  • Specify Colors: Specify up to 12 colors. To edit or remove a color, select it and then make the changes in the menu that appears. Select Clear all next to Specify Colors to remove all the colors.

Select Clear all at the top of Color and Tone to remove all color settings, and Clear all in the Gen Shape Fill dialog to remove all settings.

Select Generate in the Gen Shape Fill dialog box:

  • Variations of the fill appear in the Properties panel. The first variation automatically appears on the canvas as a Generative Object, indicated by   on its bounding box, filling the shape. The shape remains on the canvas independent of the fill.
  • A Generative Object layer appears in the Layers panel.

In the Contextual Task Bar, use the arrows to preview the variations and select the one that best suits your artwork.

You can manage the generated variations from the Properties panel or the Generated Variations panel. You can also copy the Generative Object with its linked variations or re-run Generative Shape Fill and choose how to re-run.
