Use this guide when you want to generate multiple images with the same person, model, or character.
The Characters area in Riverflow helps you reuse the same character across different generations. This is useful when you want a set of images to feel like they came from the same shoot.
Note: Only use images of people you have permission to use.
Add a character reference
Gather one or more clear images of the person or character.
Go to Characters in the side navigation, or open the character area from Photoshoots.
Click Add character.
Upload your images. If you have created a character sheet, upload the sheet as the reference image.
Name the character clearly.
Click Extract character identity.
Review the generated Prompt guidance. It should describe the person's stable identity: face shape, hair, skin tone, build, age range, and distinctive features.
Edit the prompt guidance if anything important is missing or wrong.
Click Save character.
Start generating with that character selected.
For better consistency, create a character sheet
A character sheet gives Riverflow a stronger reference than a single image. It should show the same person from multiple angles, with consistent features, hair, build, and styling.
Use this prompt in the Images section with your character references attached:
Create a clean 3x3 character reference sheet for [CHARACTER NAME].
Purpose:
This sheet will be used as a future AI generation reference. It must preserve the same character identity across all panels.
Reference priority:
- Use the supplied images only as the source of truth for face, age range, hairstyle, skin tone, body type, and distinctive features.
- Preserve the character's identity consistently across every panel.
- Do not turn the character into a different person.
- Do not make the character look younger, older, more glamorous, more muscular, slimmer, or more stylized than the references.
Sheet format:
Create a clean 3x3 grid on a neutral light grey background with thin dividers. Keep lighting soft and natural. Avoid dramatic poses, props, scenery, or fashion-editorial styling.
Panel 1: Front-facing head and shoulders, neutral expression.
Panel 2: Left three-quarter head and shoulders.
Panel 3: Right three-quarter head and shoulders.
Panel 4: Side profile.
Panel 5: Full-body standing view, neutral pose.
Panel 6: Half-body view, relaxed natural pose.
Panel 7: Expression variation 1, subtle smile.
Panel 8: Expression variation 2, neutral or focused expression.
Panel 9: Casual action pose suitable for future lifestyle generations.
Keep consistent:
- face shape
- eye shape and color
- nose and mouth shape
- hair color, length, and style
- skin tone
- body type and proportions
- age range
- distinctive marks or features
Use simple, neutral clothing unless the references show a specific outfit that should remain consistent.
Avoid:
- adding extra people
- changing identity between panels
- changing age, ethnicity, body type, or facial structure
- adding heavy makeup, dramatic styling, props, or scenery
- making the sheet look like a campaign image
Example of a character sheet
Save and use the character sheet
Once you have generated the character sheet:
Save the best sheet.
Go to Characters and click Add character.
Upload the character sheet as the reference image.
Name the character clearly.
Click Extract character identity.
Review the generated Prompt guidance and make small edits if needed.
Click Save character.
Use the saved character in Photoshoots.
The prompt guidance should describe the character's stable identity. It should not describe the grid, panels, poses, or layout of the character sheet.
Good prompt guidance usually describes:
face shape
hair color, length, and style
skin tone
age range
body type and proportions
distinctive features
any consistent styling that matters
For the most consistent results, keep the character's age, styling, and role stable across a set of generations.
