Creating Effective Characters: Best Practices

1. Start with Clear Descriptions

The quality of AI-generated characters depends heavily on your input descriptions. Be specific about:

• Physical attributes: Age, height, build, facial features
• Clothing and accessories: Style, era, materials, colors
• Personality traits: Expressions, posture, mannerisms
• Setting context: Fantasy, sci-fi, modern, historical

Example prompt:

"A 25-year-old female archaeologist with shoulder-length brown hair, wearing practical khaki expedition clothes, carrying a leather satchel, confident expression, standing in ancient ruins, realistic style"

2. Leverage Style Consistency

For game development projects, maintaining consistent character style is crucial. Consider these approaches:

• Create a style guide: Define color palettes, clothing styles, and artistic direction
• Use seed parameters: Many AI tools allow you to fix random seeds for consistency
• Batch generation: Create multiple character variations in a single session
• Reference images: Use existing character concepts as style references

3. Iterative Refinement

Don't expect perfect results on the first try. Successful character generation often requires:

• Multiple iterations: Generate several versions and select the best elements
• Fine-tuning: Adjust parameters and prompts based on initial results
• Post-processing: Use traditional editing tools to refine details
• Feedback loops: Share concepts with your team for collaborative improvement
