How to Make Your AI Characters Match Every Time
Your comprehensive Midjourney identity-locking guide for creating consistent, on-brand AI-generated characters across every scene, outfit, and pose.
The Real Reason Your AI Looks Keep Changing
When you want the same character to show up across different outfits, scenes, or poses, you need two powerful tools working in perfect harmony. Most creators struggle with consistency because they don't understand how these elements interact with each other.
Think of OMNI as your "identity anchor" — the tool that locks down who your character fundamentally is. Your moodboard acts as your "style director" — controlling the aesthetic environment your character inhabits.
When you combine both strategically, you finally get those clean, consistent, on-brand shots every single time. No more random variations that look like different people. No more off-vibe results that waste your time and credits.
OMNI
Who they are — locks down facial features, body type, and core identity characteristics
Moodboard
The vibe they show up in — controls colors, lighting, fashion, and overall aesthetic
What OMNI Really Controls
Understanding OMNI levels is crucial for mastering character consistency. Each level serves a specific creative purpose, and knowing when to use each setting will transform your workflow. Here's the complete breakdown in a beginner-friendly way that will help you make smart decisions every time you generate.
Here's the critical insight most people miss: Low OMNI (100–300) gives you new hair, new clothes, new poses every time, while High OMNI (600–1000) sticks close to your original reference. Understanding this spectrum allows you to dial in exactly the level of variation versus consistency you need for your specific project.
What Your Moodboard Controls
Your moodboard is the "vibe engine" that transforms good results into exceptional ones. While OMNI handles the identity, your moodboard orchestrates everything else that makes your images feel cohesive, professional, and aesthetically compelling.
Think of it as your silent art director — the invisible hand that ensures every image matches your creative vision. When your OMNI holds the identity and your moodboard sets the vibe, you get pure magic. Clean shots. Consistent aesthetics. Reusable images that work together as a collection.
The power of a well-crafted moodboard cannot be overstated. It's the difference between random AI outputs and a curated portfolio that looks professionally shot.

Recommended Combos (So You Don't Have to Guess)
These battle-tested combinations will save you hours of experimentation. Each combo has been refined through countless generations to give you predictable, professional results.
1
Same Character + New Outfits
OMNI: High
Moodboard: ON (--p code)
Stylize: ~100
This gives you consistency without losing creativity. Perfect for fashion lookbooks, character design variations, or content series.
2
New Scene + Same Overall Aesthetic
OMNI: Low or Medium
Moodboard: ON
Stylize: 100–140
This keeps the vibe consistent while freeing up composition and background elements for maximum variety.
3
Product + Character in Clean Realism
OMNI: Medium
Moodboard: Simple/clean set
Stylize: 80–100
Perfect for advertisements, product photography, content creators, and professional mockups.
Quick Fixes When Something Looks "Off"
Even experienced creators run into issues. The key is knowing exactly which dial to turn when something doesn't look right. These troubleshooting strategies will help you diagnose and fix common problems quickly, saving you time and credits.
Face Keeps Changing
  • Raise OMNI to High
  • Lower stylize values
  • Reuse the same seed number
  • Simplify your text prompt
Style Is Taking Over the Face
  • Lower stylize (90–110 range)
  • Use fewer moodboard references
  • Keep OMNI setting at High
  • Remove competing style cues
Pose/Background Won't Switch
  • Drop OMNI down (Max → Medium)
  • Explicitly describe new pose/angle
  • Add camera angle prompts
  • Reduce reference image weight
Mixed References = Weird Results
  • Use 2–3 references MAX
  • Use refs from same person/look
  • Remove visual outliers
  • Match lighting across all refs
The Easy Formula You Need to Remember
If you remember nothing else from this guide, remember this foundational principle that will serve you in every single generation. This is the mental model that professional AI artists use to make split-second decisions about their settings.
OMNI
Controls identity — who your character fundamentally is at their core
Moodboard
Controls vibe — the aesthetic environment and style context
Stylize
Controls freedom — how much creative interpretation AI can apply
Start with this default combo: OMNI: Medium • Moodboard: ON • Stylize: ~100
Then adjust depending on whether you want more identity control (increase OMNI) or more creative flexibility (decrease OMNI and raise stylize). This framework keeps you from fighting with the AI and gives you repeatable, gorgeous results every single time you generate.
Understanding the Identity-Style Balance
The secret to mastering Midjourney character consistency lies in understanding the delicate balance between identity preservation and creative freedom. Too much identity lock and your images become repetitive and stiff. Too much freedom and your character becomes unrecognizable across generations.
Professional AI artists think of this as a spectrum, not a binary choice. Every project sits somewhere on this continuum, and your job is to find the sweet spot that serves your specific creative needs. A fashion brand needs high consistency across outfit changes. A storyteller needs more flexibility to show their character in varied emotional states and environments.
The most sophisticated approach involves adjusting your settings dynamically as your project evolves. Start with medium settings to explore possibilities, then lock down identity once you've found your character's core look.
High Identity Lock
Maximum consistency, limited variation
Balanced Approach
Identity maintained with creative flexibility
Creative Freedom
High variation, looser character identity
Advanced Tips for Professional Results
Once you've mastered the basics, these advanced techniques will elevate your work to a professional level. These are the insider strategies that separate amateur AI art from portfolio-quality character work.
01
Build a Reference Library
Save your best generations as reference images for future projects. Organize them by character, style, and OMNI settings used.
02
Document Your Settings
Keep a spreadsheet tracking which combinations work best for different scenarios. Note OMNI values, stylize settings, and moodboard codes.
03
Test Systematically
When starting a new character, generate test grids with varied OMNI levels to find your ideal setting before committing to full production.
04
Refine Your Moodboards
Create multiple moodboard variations for different scenarios — casual, formal, action, portrait — all using the same core aesthetic.
05
Use Seed Values Strategically
Lock your seed when you find a perfect pose or composition, then vary only the elements you want to change.

Pro Tip: The most consistent results come from using the same reference image, the same moodboard, and only changing your text prompt for variations. This gives you maximum control over what changes and what stays the same.
Your Action Plan: Start Creating Consistent Characters Today
You now have everything you need to create consistently beautiful AI characters. The difference between knowing these techniques and actually using them comes down to taking action. Here's your roadmap to get started immediately and see results in your very next generation session.
Choose Your Character Reference
Select or generate your base character image. Make sure it's clean, well-lit, and shows the features you want to maintain.
Create Your Moodboard
Gather 2-3 images that represent your desired aesthetic. Keep them visually cohesive — same lighting style, similar color palette.
Start With Default Settings
OMNI: Medium, Moodboard: ON, Stylize: 100. Generate your first batch and evaluate the results.
Adjust Based on Results
Too much variation? Increase OMNI. Too rigid? Lower OMNI slightly. Keep iterating until you find your sweet spot.
Document and Repeat
Save your winning combination and use it consistently across your project. You've just unlocked repeatable, professional results.
