In this tutorial, we’ll explore how to design consistent and customizable human characters using Gemini AI. You’ll learn how to:

Use outfits that reveal the body shape for easier edits

Work with a pure white background for clean, professional results

Modify prompts to adjust body types, hair color, and facial details

Upload reference images and transform body types while keeping facial identity intact

Troubleshoot prompts when the AI doesn’t generate results as expected

We’ll create a slim male character, transform him into an overweight version, and then into an extremely athletic version—while keeping all other features consistent.

💡 Pro Tip: Even tiny adjustments in your prompt (like adding a space) can help fix failed generations.

Now it’s your turn! Copy the prompts above, experiment with your own edits, and share your best creations in the comments.
