Higgsfield Soul ID — Character Consistency

What Is Soul ID?

Soul ID is Higgsfield's character consistency system. Create a character reference once, then reuse it across unlimited generations — different scenes, angles, lighting, and actions — while the face and core appearance remain consistent.

How It Works

1. Create a Soul ID — Upload a reference image or generate one using Soul 2.0
2. The platform stores the character — assigns it an ID
3. Reference in future prompts — "using Soul ID character [name/reference]"
4. Character stays consistent — face, skin tone, basic features carry across generations

When to Use Soul ID

✅ You're building a multi-shot sequence with the same character ✅ You're creating a short film / story with a recurring protagonist ✅ You're making an AI influencer or brand mascot ✅ You want consistent faces across a product ad campaign ✅ You're doing a multi-scene action sequence and need the hero to look the same

❌ Don't use if you only need one shot — overkill for single generations ❌ Don't use if you want maximum creative variation — consistency limits style range

Prompting With Soul ID

When a Soul ID character is active, your prompt should:

1. Reference the character simply:

The Soul ID character walks through a crowded Tokyo street at night.

2. Describe what changes — not what the character looks like:

The Soul ID character now wears a formal black suit. She stands at a podium,
addressing a conference room. Camera: Dolly In toward her face.
Style: Cinematic, cool corporate lighting, 16:9.

3. You can change clothing, setting, expression:

The Soul ID character is now in a red dress, dancing alone in a ballroom.
Camera: 360 Orbit.
Style: Cinematic, warm golden chandelier light.

Key rule: Don't re-describe the face or core features — the Soul ID handles that. Only describe what is different from the base character.
