Create a Scene that Includes Custom Clipart Instructions

Prerequisites

1. Sign in so your generations can be downloaded and tracked.
2. Open the Generator from the top navigation.

Step 1: Add the First Existing Clipart Object

1. In the floating toolbar on the left side of the canvas, click the Add new object button (clipart icon).
2. The Object Sketch Carousel will open, showing available clipart objects organized by category.
3. Browse or search for a reaction apparatus component (e.g., "flask", "beaker", "condenser", "round bottom flask"). Select one that will be part of your reaction setup.
4. Click on the clipart object to select it, then click Add to Canvas. The first clipart object will appear on your canvas.
5. Position the object where you want it in your reaction apparatus layout (you can drag it to move it).

Step 2: Add the Second Existing Clipart Object

1. Click the Add new object button again to open the Object Sketch Carousel.
2. Select a second clipart object that complements your reaction apparatus (e.g., a different type of flask, a heating mantle, a stirrer, or a condenser).
3. Click Add to Canvas to place the second object on the canvas.
4. Position this second object relative to the first one to begin building your reaction apparatus layout. You can resize objects by dragging their corner handles if needed.

Step 3: Create and Add a Custom Clipart Object

1. Click the Add new object button once more to open the Object Sketch Carousel.
2. In the carousel, look for the option to create custom clipart. You may see a "Create Custom" button or a text input field where you can describe the object you want.
3. Enter a description of the custom clipart you need for your reaction apparatus (e.g., "custom adapter", "specialized connector", "reaction vessel with side arm").
4. Select the generation mode:
   1. Choose Careful mode for higher quality generation.
   2. Select Photorealistic style if available, or use Pencil sketch style (the photorealistic conversion will happen later).
   3. Optionally select Gemini 3 Nano Banana as the model for custom clipart generation if you want to preview the photorealistic style.
5. Click Generate or Create to generate your custom clipart. Wait for the generation to complete.
6. Once generated, the custom clipart will appear in the carousel. Select it and click Add to Canvas.
7. Position the custom clipart object in your reaction apparatus layout alongside the two existing clipart objects.

Step 4: Select All Three Clipart Objects

1. To select multiple objects, you can use one of these methods:
   1. Click and drag: Click and hold on an empty area of the canvas, then drag to create a selection box that encompasses all three clipart objects.
   2. Shift-click: Click the first object to select it, then hold Shift and click the second object, then hold Shift and click the third object. All three should now be selected.
   3. Ctrl/Cmd-click: On Windows/Linux, hold Ctrl while clicking each object. On Mac, hold Cmd while clicking each object.
2. When all three objects are selected, you should see selection handles around each object, and they may be highlighted or shown with a selection border.
3. Verify that all three objects (the two existing clipart objects and your custom clipart) are selected before proceeding.

Step 5: Open the Generate Image Modal

1. With all three objects selected, look for the Generate Image or Create Image button. This button may appear in:
   1. The floating toolbar above the selected objects
   2. The right-side object editor panel
   3. The top toolbar of the canvas
2. Click the Generate Image button (often represented by a camera icon or AI pen icon).
3. The Generate Image Modal will open, showing a preview of your selected objects combined together.

Step 6: Configure for Photorealistic Generation with Nano Banana

1. In the Generate Image Modal, locate the AI Model dropdown menu.
2. From the model options, select Nano-Banana 🍌 (which corresponds to "Gemini 3 Pro Image Preview" or "gemini-3-pro-image-preview").
3. Ensure the Style is set to Photorealistic. If it's not, click the Style button and select "Photorealistic" from the style options.
4. Optionally, you can add a description in the Additional Image Description field to guide the AI (e.g., "modern laboratory reaction apparatus", "professional chemistry setup", "realistic glassware").
5. Review the preview image to ensure all three clipart objects are visible and positioned as desired.

Step 7: Generate the Photorealistic Image

1. Click the Generate Image button in the modal to start the photorealistic generation process.
2. The system will process your selected clipart objects and convert them into a photorealistic reaction apparatus image using the Nano Banana model.
3. Wait for the generation to complete. This may take a minute or two depending on the complexity and server load.
4. Once generation is complete, the photorealistic image will appear on your canvas, replacing the selected clipart objects (if "Replace selected objects" is enabled) or appearing as a new object.
5. The generated image will have a photorealistic appearance, showing your reaction apparatus as if it were a real laboratory photograph.

Step 8: Finalize and Adjust

1. Review the generated photorealistic image on your canvas. You can move, resize, or rotate it as needed.
2. If you're not satisfied with the result, you can select the generated image and click the Generate Image button again to regenerate with different settings or an updated description.
3. You can also add additional elements (text labels, arrows, other objects) to complement your reaction apparatus visualization.

Tips and Notes

1. When positioning clipart objects, think about how they would be arranged in a real laboratory setup. This helps the AI generate a more realistic final image.
2. The Nano Banana model excels at converting simple clipart into photorealistic images while maintaining the composition and layout of your original objects.
3. Custom clipart generation may take longer than selecting existing clipart, so be patient during the creation process.
4. If your custom clipart doesn't turn out as expected, try refining your description or using different keywords in the description.
5. You can select up to multiple objects (typically 4 or more) for generation, but for this tutorial, we're using three objects to build a reaction apparatus.
6. The photorealistic conversion works best when objects are clearly positioned and not overlapping excessively.
