How to Maintain Character Consistency

Maintaining character consistency is crucial in AI-generated art for high-quality results. Consistent features, outfits, and details enhance coherence and immersion.

In AI-generated art, maintaining character consistency is essential for creating high-quality character images. Consistent appearance, outfits, and details enhance the coherence of the work and improve audience immersion. This guide introduces two methods to ensure the character’s appearance remains consistent across multiple generations.

Method 1: Fixed Seed

This is the simplest and fastest way, often used to create AI influencers.

The steps are as follows:

Model: The Most Pure Realism

Step 1

Generate a random character image and obtain the seed from the image.

Seed: 397096412

Prompts: Retro, beautiful female model, attractive figure, long hair, blonde, smooth skin, blue eyes, delicate makeup, beige lips, heavy eye makeup, ((draped suspender dress)), cardigan, knitted sandals, realism, open air, hyperrealistic 8K, ultra-detailed realistic, pose sculpture, hair blowing in the wind

Step 2

Use the same seed as the previous image (fixed seed) and modify some of the prompts. You can freely change the character’s background, outfit, pose, etc., while keeping other parameters the same.

Prompts: Retro, beautiful female model, seductive figure, long hair, blonde, smooth skin, blue eyes, delicate makeup, beige lips, heavy eye makeup, wearing yoga pants, realism, grass, hyperrealistic 8K, ultra-detailed lifelike, hair blowing in the wind

Prompts: Vintage, beautiful female model, seductive figure, long hair, blonde, smooth skin, blue eyes, delicate make-up, beige lips, heavy eye makeup, wearing a white dress, realistic, on the beach, she wears a shell necklace around her neck and braided bracelets on her wrists, hyperrealistic 8K, ultra detailed realistic

Prompts: Retro, beautiful female model with seductive figure, long hair, blonde, smooth skin, blue eyes, delicate make-up, beige lips, heavy eye makeup, wearing a thick down jacket with matching scarf and gloves, photo-realistic, with a fur hat on her head, climbing on snowy mountains, surreal 8K, ultra detailed realistic

This method is suitable when no reference image is available. The reference image is randomly generated by the AI, and subsequent images can retain the appearance of the first one.

Method 2: Training LoRA

Train a character LoRA using reference images of the character and set a trigger word. Then proceed with image generation.

You can refer to the following article for a detailed LoRA training guide.

3-2 LoRA Training (Advance)

This method is suitable when you have a large collection of character images, resulting in more diverse outputs.

Both methods are applicable to real-life or anime characters.
