How to Use Character Context in Image Generation

There are two ways to generate images in MegaNova Studio.

The first is the Character Image Generator — a streamlined tool for creating character avatars. Everything is structured: choose a style, a gender, a pose, an outfit, and describe the appearance. The system assembles the prompt automatically.

The second is the main Image Generation page — a full-featured editor for any kind of image. Here, you write the prompt yourself. But you do not have to start from scratch. A panel called Character Context lets you pull fields directly from any character's Blueprint and inject them into the prompt with one click.

Both tools use character data to ground the visual output in something you have already written. This guide explains exactly how each one works.

The Character Image Generator

The Character Image Generator is the faster of the two. It is designed specifically for portrait-style character avatars and makes most decisions for you.

What you configure

Style — five visual aesthetics to choose from:

Gender — Female or Male. This controls which pose and outfit lists appear. The two lists are different — Female has options like "Hair Flip" and "Mirror Selfie"; Male has "Combat Ready Stance" and "Adjusting Tie." Changing gender resets both tags to their defaults.

Pose — a tag selected from the gender-specific list. Sets the body language and framing of the shot.

Outfit — a tag from the gender-specific list. Defines the costume. Female options include Maid Costume, Gothic Lolita, Cyberpunk, Japanese Kimono and more. Male options include Business Suit, Knight Armor, Samurai Outfit, Victorian Gentleman and more.

Appearance — a free-text field for any physical description not covered by the tags above. Hair color, eye color, facial features, distinguishing marks. This is the field where character-specific detail goes. If you arrive from Quick Create, this field is pre-filled with your character hints automatically.

How the prompt is assembled

You never see the raw prompt in this tool — the system builds it from your selections:

[Style keywords]. [Gender]. pose and outfit: [Pose tag], [Outfit tag]. appearance: [Appearance text]. character portrait, centered subject, 9:16

Example with Anime / Female / Hair Flip / Gothic Lolita / appearance text filled:

anime style, high quality illustration. female. pose and outfit: Hair Flip, Gothic Lolita. appearance: long silver hair, pale violet eyes, small scar on left cheek. character portrait, centered subject, 9:16

Resolution

All outputs are portrait format. The generator automatically selects the correct resolution based on the model:

• Seedream 4.5: 1440 × 2560 (required minimum pixel count)
• All other models: 768 × 1344

Both are 9:16. You cannot change the aspect ratio in this tool — it is fixed for character portraits.

Generation quantity

The default batch size is 4 images per generation. All four are generated and displayed in the gallery. Select the one you want and apply it as the character's avatar.

Character Context in the Image Generation Page

The main Image Generation page is for unrestricted prompting. You write the prompt, choose the model, set the aspect ratio, and generate.

The Character Context panel sits below the prompt field. It appears only if you have characters with Blueprints in your space — characters without any Blueprint data filled in are excluded.

How it works

1. Expand the Character Context panel by clicking it
2. Select a character from the dropdown — only characters with blueprint data appear
3. Check the fields you want to include in the prompt
4. Click Apply to Prompt

The selected field content is prepended to whatever is already in your prompt, separated by a blank line.

The fields available

The picker exposes 11 fields across 5 groups:

Appearance

• Appearance — identity.appearance
• Style & Clothing — identity.styleChoices
• Body Impact — identity.bodyImpact

Personality

• Core Traits — identity.coreTraits (joined as comma-separated list)
• Quirks — identity.quirks (joined as comma-separated list)
• Voice & Speaking Style — identity.voiceStyle

Scene

• Current Situation — background.currentSituation
• Scene Setting — dialogue.firstMessageContext.setting
• Character Action — dialogue.firstMessageContext.characterAction

Background

• Origin — background.origin
• World — background.world

Tagline

• Tagline — identity.tagline

Fields with empty content in the Blueprint are greyed out and cannot be selected. They appear at the bottom of the list under an "Empty fields" divider — a signal that those fields need content before they can contribute.

The format injected into the prompt

When you click Apply, the picker formats the selected fields as:

[Character Name] — [Field Label] content. [Field Label] content. [Field Label] content...

Example with Appearance, Style & Clothing, and Scene Setting selected:

Kaelin Drakonis — [Appearance] waist-length silver hair, amber eyes, weathered indigo coat. [Style & Clothing] scholar's ink-stained fingers, brass-buttoned travel coat. [Scene Setting] standing at the edge of a rain-soaked rooftop overlooking the city at dusk.

This text is placed before your existing prompt. You can edit it freely after applying.

Which Fields to Use for Which Goal

Not every field contributes equally to image generation. Personality and Voice fields describe behavior, not visuals — they rarely improve image output. The fields that matter most depend on what you are generating.

Character portrait (T2V or standalone image):

• Appearance ✓ — the most important field for visual accuracy
• Style & Clothing ✓ — outfit and aesthetic
• Tagline ✓ — sets the tonal mood if distinctive
• Everything else ✗ — personality and background add noise without visual signal

Scene or environment shot:

• Scene Setting ✓ — where the character is and the atmosphere
• Character Action ✓ — what they are doing in frame
• World ✓ — informs the visual texture of the environment
• Origin ✓ — cultural and world aesthetic
• Appearance ✓ — if the character is in frame

Establishing shot (no character):

• World ✓ — the macro visual context
• Scene Setting ✓ — the specific place and time
• Tagline ✓ — if evocative enough to color the mood
• Appearance ✗ — no subject to describe

Testing a new look:

• Appearance ✓ — one field is enough to test
• Everything else ✗ — keep the prompt minimal to isolate what is changing

What the Blueprint Quality Means for Output

The Character Context system pulls content verbatim from the Blueprint. It does not interpret or rewrite it.

A one-line Appearance field produces a one-line image prompt. A detailed, specific Appearance field — hair color and length, eye color, specific clothing items, distinguishing physical features — produces a prompt with enough information for the model to work from.

If the generated images are generic, the prompt is generic. And the prompt is generic because the Blueprint field is generic.

The fix is in the Blueprint Editor, not the image generation settings. Fill in the Appearance and Style & Clothing fields with the detail you would want in an image prompt — because that is exactly where it ends up.

The Full Workflow

For a character avatar (Character Image Generator):

1. Select your style and gender
2. Choose a pose and outfit from the tag lists
3. Fill in the Appearance field with physical description
4. Set quantity (default 4) and generate
5. Select the best result and apply it as the character's avatar

For a scene or standalone image (Image Generation page):

1. Write your base prompt or leave it empty
2. Expand Character Context, select your character
3. Check the fields relevant to your generation goal
4. Click Apply to Prompt — review and edit the injected text
5. Set model, aspect ratio, and generate

In both cases, the output quality is proportional to the specificity of what is in the Blueprint.
