[Hands-On] How I Unified a Character's Appearance Using Midjourney v7's Omni-Reference

Hello. My name is Momoi (@momoitter), and I’m a designer in the Creative Office at KINTO Technologies.

In this article, I’ll walk through the process of using Midjourney V7’s new Omni-Reference feature to keep the look of the original character KTC AI WEB consistent.

This article is for:

• Those who want to learn more about Omni-Reference in Midjourney V7
• Those looking to generate character images with a consistent look
• Those interested in creating high-quality visuals using AI tools

I’ll walk through how to use Omni-Reference, along with tips for fine-tuning, using actual prompts and generated images.

What is Omni-Reference?

In May 2025, a long-awaited feature called Omni-Reference was introduced in Midjourney V7.

This feature allows you to generate new images while maintaining visual consistency by referencing a specific image. It is now possible to maintain characterization, which was previously difficult in V7, and it’s not limited to people; it works with objects and vehicles, too.

There’s also a parameter called Omni Strength (ow), which lets you fine-tune how closely the output follows the reference image using numerical values.

About "KTC AI WEB"

What is KTC AI WEB?

In November 2024, an AI-generated character named KTC AI WEB made her debut in the opening video of KINTO Technologies’ internal event CHO All-Hands Meeting.

Since then, she’s served as a navigator, appearing at developer events and recruitment events to help introduce KINTO Technologies.

Why Unify Her Appearance?

Since the birth of KTC AI WEB, image and video generative AIs have evolved rapidly. As a result, her original visuals started to feel a bit outdated.

Shortly afterwards, Midjourney V7 and Runway Gen-4 were released, dramatically improving generation quality. We also decided to update KTC AI WEB’s visuals at this time.

However, while V7’s expressive power is extremely high, it didn’t initially offer a way to keep a character’s appearance consistent. KTC AI WEB’s face changed slightly with each generation.

Furthermore, while the update improved quality, it came with a side effect—some of KTC AI WEB’s original approachable charm faded.

Meanwhile, in May 2025, a new feature called Omni-Reference was added to Midjourney V7.

I used this feature to reconstruct an "evolved KTC AI WEB" that combines the beauty and realism of V7 with the original character’s look and feel.

Let’s Put it into Practice!

Consulting ChatGPT

To start, I asked ChatGPT the following:

I want to upload an image to Midjourney V7’s Omni-Reference to generate a front-facing image of this pink-haired female character with a clean background while keeping her look consistent. Give me some prompts for Midjourney."

ChatGPT responded with these prompts:

upper body portrait of a female virtual operator in a clean futuristic interior, facing camera directly, symmetrical composition, looking straight ahead, centered, gentle expression, slightly relaxed face, subtle smile, brightly illuminated face, soft front lighting, high key lighting on the face, studio-style lighting setup, clear and vivid facial features, softly lit background, minimalistic sci-fi control room, white and silver tones, crisp details

How to Use Omni-Reference

Step 1: Drag and drop the image

Drag the image you want to reference into the Midjourney prompt input box. A bar labeled Omni-Reference will appear at the top of the screen, drop it there.

Step 2: Adjust Omni Strength (ow)

Omni Strength allows you to adjust the strength of consistency (how closely the output matches the reference image). The numerical value is specified by the parameter called ow.

Step 3: Start generating

Enter the prompt you got from ChatGPT and start generating!

Changes by "ow" values

• Low ow (e.g. 100-200): Less similar to the original image, but with Midjourney’s signature soft, beautiful rendering.
• High ow (e.g. 800-1000):Closer to the original image, but with less of Midjourney’s distinctive feel.

ow100

ow200

ow400

ow600

ow800

ow1000

Finding the Right Balance

After much trial and error, I found that setting ow between 200 and 400 worked best for updating KTC AI WEB. With these values, the output preserved her original features while still capturing Midjourney’s signature soft, beautiful rendering.

At one point, "This is it!" I came across an image that felt just right. It was the ideal image capturing KTC AI WEB’s feature with Midjourney’s signature fine, delicate beauty.

Expanding Scenes and Building a World

Using the final image as a base, I expanded the composition and backgrounds using Omni-Reference. I also consulted ChatGPT again to get scene ideas and prompts for Midjourney.

Having a solid base made it easier to build out a consistent world around her.

The updated look for KTC AI WEB is also featured at the start of the company’s introduction video. https://www.youtube.com/watch?v=8Df_0StDAiw

Application: Expanding to Other Internal Content

KTC AI WEB was also featured in presentation materials for a recent internal study session. Thanks to Omni-Reference, there’s no need to stress over whether the visuals stay on-model, making it much easier to use her across slides, event visuals, and other materials.

Tips Learned Through Practice

Omni-Reference is a very powerful feature, but the reference can be too strong.

• Want to change the outfit -> Attach an image that only shows the face
• Want to change the hairstyle, too -> Focus on just the eyes or another minimal area

Fine-tuning the reference range like these allows for consistent facial features while preserving Midjourney’s signature creative flexibility.

Summary: A Time When Anyone Can Create "KTC AI WEB"

The introduction of Omni-Reference has made it possible to create high-quality scenes while maintaining consistent character visuals.

In other words, we’ve entered a time when anyone can create something like KTC AI WEB.

It feels like a waste to keep her confined to my own imagination. That’s why I hope KTC AI WEB will continue to grow through the creativity of everyone in the company.

I want to expand the range of expression and help her spread her wings even further. As AI technology continues to evolve, so will KTC AI WEB.
