description: "Creates and manages reusable character profiles (Soul IDs) for consistent facial and stylistic identity across multiple image and video generations. Provides identity-vs-motion prompt separation, character sheet creation workflows, micro-expression direction, and Soul Cast AI actor configuration. Use when the user wants to maintain character consistency across multiple generations, asks about Soul ID, creating reusable characters, or generating consistent people across different scenes and shots."

Higgsfield Soul ID — Character Consistency

QUICK FACTS

*Generated-checked block (scripts/build_index.py verifies anchors). Read the linked sections for full context — these lines are routing aids, not the rules themselves.*

• Hard rule: every Soul ID prompt splits into Identity Block (static descriptors only) + Motion Block (temporal/camera only) [→](#identity-vs-motion-separation--hard-rule)
• Don't re-describe the face or core features — only describe what differs from the base character [→](#prompting-with-soul-id)
• Reference image rules: front or 3/4 angle, even lighting, neutral-to-slight expression, no blur, solo subject [→](#creating-a-strong-soul-id-reference)
• Reference generators: Soul 2.0 (fashion-forward), Nano Banana Pro (max sharpness), Seedream 4.5 (style range) [→](#creating-a-strong-soul-id-reference)
• Character sheet angles: front face, 3/4, side profile, optional full body + optional embedded prop sheets [→](#character-sheet-creation)
• Two-image floor per character: one clear face + one full body, on neutral grey — never a single image; the grey law's shade and mechanism live once in `../../templates/ad-asset-prep.md` [→](#character-sheet-creation)
• **The Untouched Base**: face pass in close-up, then a looks pass; the base close-up is never run through a model again — changes go on with masks, and a new state is a new named asset [→](#the-untouched-base--build-a-character-in-two-passes)
• **Reference plates**: biological realism ON, photographic capture behaviour OFF (no key direction, cast shadow, bokeh, flare); the background is a field, not a room; lean prompts once a reference carries identity [→](#the-reference-plate--the-two-axes)
• Prefer the single-prompt 3×2 six-panel sheet (one 16:9 generation) — identity locks better than multi-step assembly [→](#single-prompt-6-panel-character-sheet-32-grid)
• Outfit change without identity drift: split-panel sheet — ghost-mannequin outfit LEFT + "face matches input 100%" close-up RIGHT [→](#split-panel-outfit-change-sheet-ghost-mannequin--identity-panel)
• Crowds: a single-character reference makes a clone army — build a multi-character lineup and declare it a "VARIETY reference" [→](#variety-sheets--crowds-without-clones)
• Character Anchor Block = 10 per-shot attributes (identity, screen position, depth layer, frame occupancy, orientation, pose, gaze, contact points, state lock, expression) [→](#character-anchor-block)
• One Soul ID sheet PER character state — 5 transformation stages = 5 distinct sheets; the prompt names the stage [→](#multi-form-state-tracking)
• Micro-expression presets: 9 core + 10 extended [→](#core-set)
• Cinema Studio: identity goes in the @ Element definition, motion goes in the prompt field [→](#beforeafter-examples)
• Soul Cast is Business/Team plans only; 8 parameter categories incl. 12 Archetypes, Budget $10M–$500M, Era 1900s–2020s [→](#cinema-studio-30-soul-cast-businessteam-plan)
• Soul Cast specs: up to 4K (Character/Location modes) / 2K (General); batch 1 or 10; 0.125 credits per image [→](#30-soul-cast-specs)
• Use 2–3 reference shots (frontal, 3/4, side); if features drift, use the character sheet as @Image1 [→](#character-consistency-best-practices)
• Soul Cinema is the default CS 3.0/3.5 image-mode model — single-step, ~0.125 credits/image [→](#soul-cinema-as-the-cs-3035-default-image-model)
• Studio-feeling output is an intermediate, not a final — re-pass through Soul Cinema with grade, directional lighting, lens character; the result is a derived look frame, never the identity base or a reference plate [→](#studio-look-vs-cinematic-look--soul-cinema-as-the-re-pass)
• Skip Soul ID for single shots or when you want maximum creative variation [→](#when-to-use-soul-id)
• Plasticky face in wide shots: crop the face from a closer-shot panel and replace it in post [→](#face-from-wide-shot-workaround)
• Casting a REAL person: the sheet alone returns a lookalike — erase the head on the body panels and paste their actual photo into the portrait panel [→](#the-hybrid-sheet--casting-a-real-person)
• Run the same sheet prompt through 2–3 image models and compare before locking; the deciding axis changes per character [→](#pick-the-sheet-model-per-job-not-per-project)

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 wan
