Generate vector artwork in Adobe Photoshop that conforms precisely to custom shapes using the Generate Shape Fill feature. Whether you're working with simple rectangles or complex hand-drawn outlines, this article shows how to fill any shape with AI-generated designs based on your prompts.
Key Insights
- Using the Generate Shape Fill feature in Photoshop allows artwork to be seamlessly generated within any vector shape, including ellipses, organic curves, and hand-drawn outlines.
- The generated vector fills are editable, meaning anchor points can be adjusted with the Direct Selection Tool, and the artwork remains part of the shape rather than a mask.
- This AI training course demonstrates how varying shapes, from rectangles to freeform paths, produce different styles of generative floral artwork, showcasing the flexibility of AI-assisted vector design.

Let's continue working with generated vectors. I’m going to start by clicking Generate Vectors again and entering a very simple prompt, flowers. I’m not changing any settings, just typing the prompt and generating the result.
As you can see, the generated flowers look very nice, but they appear more like a rectangular composition. To change that, I can move this artwork up and create a new shape instead.
I’ll select the Rectangle Tool and draw a large rectangle near the bottom of the canvas. With that shape selected, I can choose Generate Vectors again and enter the same prompt, flowers. This time, the flowers are generated to fit within the rectangle, creating more of a landscape-style composition that follows the shape.
The results here are not perfect, but if I cycle through the variations, you can see Photoshop attempting different layouts. Some versions look more vertical, while others resemble a bouquet-style composition.
If you want the generated artwork to conform precisely to a shape, you can use Generate Shape Fill instead. For example, I’ll select the Ellipse Tool and draw a large ellipse. I’ll add a black stroke so the shape is easy to see, then switch back to the Selection Tool.
With the ellipse selected, I click Generate Shape Fill and enter the prompt flowers. When I generate, Photoshop creates three variations that fill the entire ellipse. You’ll notice that the artwork follows the shape perfectly. This is not a pattern; it’s a generated vector fill that adapts exactly to the shape you created.
To demonstrate this further, I’ll create a more complex shape. Using the Curvature Tool, I’ll place a few points and form an organic shape, something irregular, almost like a bean. Once the shape is complete, I select it and choose Generate Shape Fill, again using the prompt flowers.
Even with this more complex shape, Photoshop generates floral artwork that conforms to the outline. You can adjust prompts, colors, or styles, but here the goal is simply to show how flexible shape-based generation can be.
These shapes are fully editable. If I use the Direct Selection Tool, I can see and adjust the anchor points. This is not a mask; the generated artwork is applied directly to the vector shape. If I separate or inspect the shape, you can see that it remains a standard vector object.
You can also draw shapes freehand. For example, I can use the Pencil Tool to draw a loose, irregular shape across the canvas. After switching back to the Selection Tool, I can apply Generate Shape Fill once again and enter flowers.
Even with a rough, hand-drawn shape, Photoshop fills the area with generated floral artwork. This is useful if you want something more organic or complex than basic geometric shapes. For example, you could create the outline of a jar, a patch of grass, or a decorative area filled with flowers or other elements.
The key idea here is that the generated vector fills adapt to any shape you create, whether simple or complex. Now it’s your turn to experiment with these tools and explore different shapes and prompts.
