How to Fix Faces in Nano Banana: The Ultimate Consistent Character Workflow (JSON Included)

Why Your Nano Banana Characters Look Different Every Time

You type "beautiful girl in office," then "beautiful girl at beach," but the face looks like a completely different person. Does this sound familiar? This is the #1 problem with standard text prompts used by sites like PromptHero or ArtHub.

The solution is not "better keywords." The solution is JSON Workflow Injection.

Step 1: The "Face-Lock" JSON Code

Stop guessing. Copy this specific JSON block and paste it into your Nano Banana advanced settings. This code forces the AI to memorize facial landmarks (eyes, nose bridge, jawline).

{
  "workflow_mode": "consistent_character",
  "face_id_weight": 0.85,
  "reference_image": "UPLOAD_YOUR_IMAGE_HERE",
  "facial_structure": "locked"
}

Step 2: How to Use It (The 1-Click Method)

1. Open Nano Banana Pro.
2. Switch from "Text Mode" to "Workflow Mode".
3. Paste the JSON code above.
4. Upload your reference selfie.
5. Result: Now you can put that SAME face on a superhero, a pilot, or a wizard without losing identity.
