Character Sheets

One of the main problems for video creators has always been maintaining the consistency of a character throughout various scenes, where poses change and AI often applies new, inconsistent features to provide what it can't see. This problem has recently been definitively solved with the creation of Character Sheets. A Character Sheet shows all the features and details of a character's body and face from different points of view, starting from a single reference image. To illustrate the process of creating a Character Sheet, I'll start with a single image of one of my favorite models, Diana. Here she is: Now I upload this image as reference image in the image-to-image section of BP, using the following prompt with Nano-Banana-Pro model (160 credits): " Create a professional character reference sheet based strictly on the uploaded reference image, preserving and exactly matching its existing visual style. Do not change the realism level or rendering approach; keep the same type of image as the reference (for example, if the reference is photographic, keep it photographic), with the same shading, texture, color treatment, and overall aesthetic. Use a clean, neutral plain background so the character is clear. Arrange the sheet so that the left side contains two large full body panels of the character in a relaxed pose with accurate anatomy and proportions: one full body front view and one full body back view, with consistent scale and alignment between them. On the right side, create four portrait panels arranged in two rows: a front portrait with the face looking straight at the camera, a lateral portrait (profile facing left), a side portrait (profile facing right), and an extreme close up face crop that clearly shows fine facial details such as eyes, eyelids or eyelashes, eyebrows, nose, mouth, skin or surface texture, and hair or head details. Maintain perfect identity consistency across every panel so the character always looks like the same individual from the reference image. Keep the facial scale consistent across the three standard portraits, and use even spacing and clean visual separation between all panels. Lighting should remain consistent across the entire sheet (same direction, intensity, and softness as in the original style), with controlled shadows that preserve detail without dramatic mood shifts, producing a crisp, print ready reference sheet with sharp details. " Be sure to enter the whole prompt, even if it exceeds the number of characters. Select 16:9 and 2K, or better 4K (more expensive). Here is one of the results you may get: As you can see, the character is defined in all its relevant details. Although Nano-Banana-Pro is suggested as the preferred model for Character Sheet creation, I often use SeeDream 4.5 which is cheaper (45 credits) and gives excellent results, as you can see in the following image: Moreover, for those who are interested, SeeDream 4.5 allows the creation of NSFW Character Sheets, while Nano-Banana does not. Alternatively, you can create Character Sheets with the following prompt: " Create a professional character reference sheet based strictly on the uploaded reference image. Use a clean, neutral plain background and present the sheet as a technical model turnaround while matching the exact visual style of the reference (same realism level, rendering approach, texture, color treatment, and overall aesthetic). Arrange the composition into two horizontal rows. Top row (three-quarters of the height of the sheet): four full-body standing views placed side-by-side in this order: front view, left profile view (facing left), right profile view (facing right), back view. Bottom row (a quarter of the height of the sheet): four highly detailed close-up portraits aligned beneath the full-body row in this order: front portrait, profile portrait facing left, profile portrait facing right, back view. Maintain perfect identity consistency across every panel. Keep the subject in a relaxed pose, with consistent scale and alignment between views, accurate anatomy, and clear features; ensure even spacing and clean panel separation, with uniform framing and consistent head height across the full-body lineup and consistent facial scale across the portraits. Lighting should be consistent across all panels (same direction, intensity, and softness), with natural, controlled shadows that preserve detail without dramatic mood shifts. Output a crisp, print-ready reference sheet look, sharp details. " Here is one of the possible results obtained with Nano-Banana-Pro (2K): And here is what you can get with SeeDream 4.5, using the same prompt (4K): It is always recommended to use the best resolution available, preferably 4K. Now, whatever model you'll use to create a video, upload the Character Sheet as a reference image, describing in the prompt the action you want your character to perform and the environment or background, and the consistency of your character will be ensured throughout the video. Many useful example of this process are available on YouTube.
