Avatar Builder turns a person description or your own photos into a saved avatar you can reuse in Generate. You review the person before using them across products and scenes. Meet Mara, the avatar we created for this walkthrough. Both photos below use the same saved avatar and a coordinated outfit description: a chocolate wool blazer, ivory knit, ecru denim, and brown loafers. We used Nano Banana Pro, 4K, with soft window light for one photo and an overcast street setting for the other.

Build the avatar

1

Define the person

Open Avatar Builder in the Studio sidebar. Choose a gender option and add the appearance you want under Attributes. Press Enter to add an attribute; you can also paste a comma-separated list.For Mara, we used:
Describe stable features here. Choose the outfit, setting, and campaign pose later in Generate.Choose an image model and quality, then review the displayed credit cost. Our starter used Nano Banana Pro, 2K; the saved reference set below used Nano Banana 2, 2K.

Start with a small set of clear appearance details.

Starting from a real person? Add source photos instead. Use clear photos of the same person, with an unobstructed face and consistent appearance. You can add up to eight photos you have permission to use. With source photos, the builder can go directly to generating references.

Review the starter portrait

When starting from a description, choose Generate Starter. Check the face, hair, age, and overall appearance when it finishes.Use Regenerate if the person is not right yet. When the starter looks good, choose Generate References.

Approve the person before creating the reference set.

Check all four views

The builder creates a Neutral Headshot, 45-Degree Headshot, Full-Body Front, and Full-Body Angled Pose. Together, these give future generations face and body references from different views.Inspect every image. The face, hair, skin tone, and proportions should describe the same person. Headshots should be clean portraits; full-body views should include the feet without awkward crops or extra body parts.

If one view needs work, use Regenerate on that card. Changes to Characteristics apply to the next regeneration; they do not rewrite finished images. Wait until all four views are ready, then choose Continue to Save.

Save a recognizable name

Enter an Avatar Name, review the reference thumbnails and description, then choose Save Avatar. We named this one Mara.

Save the reviewed references as a reusable avatar.

Use the avatar in Generate

Open Generate, select the Avatar tile, and choose the saved avatar. Add your garment and a preset, then generate a first product photo.Keep the avatar selected for the next image. Change the product, pose direction, or preset according to the shot you need, and compare each result with the references.

​
Make the identity easier to keep

  • Reuse the saved avatar instead of re-describing a similar person each time.
  • Keep faces clear and avoid conflicting person references in the same generation.
  • Check a neutral product photo before introducing dramatic lighting or strong profile views.
  • Review the set together. We optimise the workflows for high accuracy, but occasional mistakes can still happen.
