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.

In the prompt field, type in a description of the fill you’re looking for. Prompt suggestions guide you as you type, helping you add more detail. The prompt is optional, but without it, the fill will be based entirely on the outline of the shape.

Tip

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

To adjust how closely the variation matches the shape and how detailed it is, select Shape strength and detail and move the sliders as needed.

  • Shape Strength: 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: When set to High, the fill will include fine details. When set to Low, the fill will have a smoother appearance, closer to that of real-life objects without always capturing every small feature.

To change the style or add a reference, select Style Reference and adjust the setting 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.
Note

Select Clear all next to Styles to remove Style reference, Effects, and Color and Tone.

To adjust the color and tone for your fill, select View all settings 

In the Gen Shape Fill dialog box that opens, select Color and Tone and change the settings as needed:

  • 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: Select up to 12 colors to include in the fill. To edit or remove a color, select it and then select Color and make adjustments using the sliders or enter a hex number in the text field. 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 generated object, indicated by a sparkle   icon on its bounding box, filling the shape. The shape remains on the canvas independent of the fill. A Generative Object layer is also created 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.
