Technical Term Explanations

Core Concept Analysis

LoRA Fine-tuning Model: A lightweight AI model that allows training visual consistency for specific characters without changing the original model. It can be understood as giving AI a "character visual handbook."

Character Feature Embedding: Converting a character's core features (such as hairstyle, clothing details) into data labels, allowing AI to consistently retain these features during generation. This is like giving a character a unique "visual DNA."

Interdisciplinary Theory Integration

Jungian Archetypes and AI Generation

In the concept ideation phase, we can combine Jungian archetype theory with AI generation:

For example, when generating a character based on the "Shadow Archetype," we can prompt the AI: "Please generate a character based on the 'Shadow Archetype' - a seemingly righteous character with a dark secret, including 3 subversive traits, such as a hero showing cowardice at critical moments."

This combination helps creators develop characters with greater psychological depth, avoiding overly flat characterizations.

MBTI Personality Model and AI Psychological Profiles

In the psychological depth development phase, we can combine the MBTI personality model with AI psychological profiles:

For example, using ChatGPT to generate defense mechanisms for an INFJ personality character, then simulating their dialogue reactions in stressful scenarios through Character.AI. This combination helps creators better understand the character's psychological state and behavioral patterns.

Prompt Engineering Layered Guidance

Basic to Advanced Prompt Design

Taking Midjourney as an example, prompt design can be divided into three levels:

Basic level prompt: "Generate a female character wearing steampunk clothing, with brown short hair and a mechanical eye."

Style level prompt: "Add cyberpunk lighting, reference the high-contrast color scheme of Blade Runner, character holding a gear-shaped weapon."

Narrative level prompt: "The character's left mechanical eye hides an identity chip, expression revealing disgust with the mechanical body, background set in an abandoned gear factory."

Counterfactual Prompt Techniques

To explore character development possibilities, we can use counterfactual prompts:

"Generate a character variant completely opposite to the initial concept, such as transforming an optimistic character into a depressive version, for exploring character arc possibilities."

Tool Integration and Workflow

Three-Modal Character Creation Process

A complete character creation process can follow these steps:

1. Use Claude to generate character core contradictions, such as "desiring love but fearing intimacy."

2. Generate 3 visual solutions through Midjourney: melancholic version, disguised happy version, and indifferent version.

3. Use Character.AI to simulate dialogue differences under different visual solutions.

4. Select the visual-dialogue combination that best matches psychological logic, then generate corresponding voice lines with ElevenLabs.

Tool Conflict Resolution

When AI-generated visual images conflict with text personality, we can resolve this through:

1. Adding personality keywords to prompts, such as "introverted," "anxious," etc.

2. Adding visual constraints, such as "avoid exaggerated expressions," "maintain restrained body language," etc.

3. Conducting multiple iterations, gradually adjusting visual elements to match psychological characteristics. Ready to develop more compelling characters? Apply these techniques in conjunction with our guides on character design fundamentals and creating memorable character backstories to create truly unforgettable characters for your stories, games, or creative projects.
