Getting Ensuring Character Consistency Across Generations right takes more than a single prompt. This 4-stage guide covers Diagnose the Wall, Isolate and Fix, Verify the Resolution, and more, breaking the whole process into focused steps where each prompt builds on the last. Inconsistent character appearances across generations can be frustrating as it disrupts the visual storytelling or branding efforts. This inconsistency can lead to wasted time and resources in refining designs. By following these prompts and techniques, creators can achieve a more uniform look for their characters or objects across multiple generations. Every prompt is optimized and runs in ChatGPT, Claude, and Gemini.

Diagnose the Wall

Start by testing different aspects of your prompt to identify what causes the inconsistencies in character appearance. This will help isolate the root cause of the problem.

Test Core Subject

Run a baseline test prompt using only the core subject: '[CHARACTER NAME]'. Analyze the AI's interpretation of this subject and provide insights on how it understands the character without any additional descriptors or stylistic influences. Include any notable strengths or weaknesses in the AI's response.

Diagnose the Wall

Use a Reference Prompt

Provide a known-working reference prompt that has successfully generated the character before. For example, use '[CHARACTER NAME], [STYLE], [BACKGROUND]' and analyze the output to determine if the issue lies within your current prompt. Explain any differences you observe and suggest adjustments to improve consistency.

Diagnose the Wall

Change One Parameter

Modify one parameter at a time in the character design, starting with changing the style preset to '[STYLE PRESET]'. After each modification, analyze the impact on character consistency and document any noticeable changes in appearance or behavior.

Diagnose the Wall

Generate Variations

Generate four variations of the prompt '[CHARACTER NAME], [STYLE], [BACKGROUND]'. After generating these variations, compare the outputs to evaluate the differences in character appearance and identify any inconsistencies in the portrayal of the character across the variations.

Diagnose the Wall

Compare Against Reference

Generate an image of the character based on the description provided. Then, compare this generated image against a reference image of the character. Identify and describe specific differences in features, colors, and overall style, highlighting any inconsistencies that may affect the character's representation.

Diagnose the Wall

Isolate and Fix

After diagnosing the issue, apply specific techniques to fix the inconsistencies in character generation. These adjustments will help ensure a more uniform appearance.

Add Specific Descriptors

Rephrase your prompt to include specific descriptors for the character. For example, use '[CHARACTER NAME], [HAIR COLOR], [EYE COLOR], [CLOTHING STYLE]' to provide clear details. This will ensure the AI can maintain consistency in the character's portrayal throughout the narrative.

Isolate and Fix

Incorporate Negative Prompts

Incorporate negative prompts to exclude unwanted variations in the generated content. Specify the exact negative prompts you want to use, such as "no distortions" and "no variations in hair color," and explain how these exclusions should guide the AI to produce more consistent results.

Isolate and Fix

Change Style Mode

Change the style mode to 'Custom' and describe the desired style for the character. For example, specify the character as '[CHARACTER NAME]' and detail the art style you want, such as '[SPECIFIC ART STYLE]', to ensure visual consistency throughout the project.

Isolate and Fix

Restructure Prompt Order

Restructure the prompt by placing the subject first and the style last. For example, format it as '[CHARACTER NAME], [BACKGROUND], [STYLE]'. Explain how this organization can help the AI prioritize the subject's features effectively and provide an example of a prompt using this structure.

Isolate and Fix

Lock the Seed

Lock the seed value for randomization in the nano-banana project to ensure consistency across generations. Specify a seed number, such as [SEED NUMBER], and explain how using this seed will affect the output results in terms of reproducibility and reliability.

Isolate and Fix

Verify the Resolution

Once adjustments are made, verify that the changes have resolved the inconsistencies. Run tests to confirm the effectiveness of the fixes.

Generate New Variations

Generate four new variations based on the prompt: '[CHARACTER NAME], [HAIR COLOR], [EYE COLOR], [CLOTHING STYLE]'. Ensure that each variation maintains consistency in character traits and style, and provide a brief explanation of how each variation aligns with the original prompt.

Verify the Resolution

Compare with Baseline

Compare the new outputs for the character's appearance against the Stage 1 baseline prompt. Analyze the uniformity in features and style, and provide a detailed assessment of any inconsistencies or improvements observed in the character's design.

Verify the Resolution

Test with Harder Subject

Test the AI's ability to maintain character consistency by generating an image of '[CHARACTER NAME] in an action pose'. Ensure that the character's features, colors, and style remain consistent with previous representations while adapting to the dynamic pose.

Verify the Resolution

Lock Seed and Generate

Lock the seed and generate a new image using the following prompt: '[CHARACTER NAME], [BACKGROUND], [STYLE]'. Ensure that the generated image reflects the character's consistency with the locked seed by comparing it to previous images created with the same seed. Provide a brief analysis of any differences observed.

Verify the Resolution

Check Different Aspect Ratios

Check the character consistency by running the same prompt at a different aspect ratio, specifically 16:9. Analyze the output for any variations in character appearance or behavior compared to the original aspect ratio, and summarize your findings on how the aspect ratio influences character consistency.

Verify the Resolution

Prevent Recurrence

To avoid future inconsistencies, create reusable templates and workflows that ensure uniformity in character generation. These templates will streamline your process.

Base Prompt Template

Generate a character for the Nano Banana universe using the following template: '[CHARACTER NAME], [HAIR COLOR], [EYE COLOR], [CLOTHING STYLE]'. Ensure that each variable is filled with unique and creative details that fit the theme of the game, and provide a brief backstory for the character that highlights their personality and motivations.

Prevent Recurrence

Negative Prompt Bank

Create a negative prompt bank that includes phrases such as 'no distortions' and 'no variations in hair color'. Provide at least ten additional phrases that can help maintain character integrity across various scenarios, ensuring that these phrases are clear and specific for consistent use in prompts.

Prevent Recurrence

Seed-Locking Workflow

Establish a seed-locking workflow by locking the seed before generating images. Specify a seed number, such as [SEED NUMBER], for all character generations to ensure consistency across outputs. Explain how this method prevents inconsistencies in character appearance and provide examples of how to implement it effectively.

Prevent Recurrence

Style-Consistency Checklist

Create a style-consistency checklist that includes the following elements: [CHARACTER NAME], [STYLE], and [BACKGROUND]. Ensure that this checklist is comprehensive enough to guide the structuring of all prompts in a uniform manner, highlighting specific criteria for each element to maintain consistency across different entries.

Prevent Recurrence

Parameter Combination Template

Create a parameter combination template for character style that includes the following elements: [CHARACTER NAME], [HAIR COLOR], [EYE COLOR], [CLOTHING STYLE], and [STYLE PRESET]. Ensure that this template serves as a foundational guide for every character generation, allowing for consistent and varied outputs based on these parameters.
