Character Reference Sheet Prompt Template for ChatGPT image 2.5

X postM. AsifResource

M. Asif shares a detailed prompt framework designed for ChatGPT image 2.5 to turn a single reference image into a multi-panel character production model sheet, aiming for strict identity preservation across angles and poses.

Key points

  1. Generates a 16:9 studio-style model sheet using an uploaded image as the single source of truth for identity.
  2. Structured sections cover a hero portrait, full-body turnarounds, a six-expression grid, signature poses, and detailed callouts.
  3. Includes dedicated areas for material definition, an anchored colour palette, and technical proportion guides.
  4. Design continuity rules explicitly prevent the model from altering proportions, facial features, or costume details.
  5. The author positions the sheet as a production foundation for subsequent image or video workflows, though some users note potential tool-specific limits.

Why it matters

Character consistency across varying perspectives, actions, and expressions remains a core bottleneck in generative workflows. Formalised model sheets provide models with anchored reference data.

Analysis

By adapting classical production workflows from animation and concept design into a prompt, this method forces the image model to commit to specific proportions, outfits, and materials. While this establishes clear visual anchors, community feedback highlights trade-offs: packing multiple panels and guides into a single image can yield smaller facial resolutions that downstream video tools may struggle to interpret.

  1. @itsshara_ai @ChatGPT Exactly. A strong reference sheet gives the model a visual source of truth and makes consistency much easier to maintain.
  2. @Viniai_ @ChatGPT Thank you! That was the goal — something genuinely useful for a production workflow, not just a pretty reference.
  3. @afrinxai @ChatGPT Absolutely. The right prompt structure makes a huge difference in getting consistent, usable results.
  4. @m_zubaair @ChatGPT Appreciate it, boss! 🙌 Glad you found it useful.
  5. @nadiaai530 @ChatGPT Thank you! Consistency across angles and expressions was one of the main priorities behind the workflow.
  6. @aiseomastery @ChatGPT It really does. The identity lock helps keep the character anchored while still allowing different poses, angles, and expressions.
  7. @petradyn @ChatGPT 🙌 Appreciate it!
  8. @francisluz @ChatGPT It can work for both. The main purpose is to establish a consistent character foundation that can then be carried into different image or video workflows.
  9. @LocalBananaAI @ChatGPT Exactly — those recurring visual anchors are what make the character recognizable across different views.
  10. @heygulati @ChatGPT Thank you! I wanted the sheet to be detailed enough to actually support a production workflow.

  • @renatolaurino @meAsifAi @ChatGPT In my tests, this overly comprehensive sheet actually produced worse results. It’s simply too much information for Seedance to handle effectively. Small faces tend to become inconsistent, and you often get all sorts of unnatural expressions. “Material studies” and “proportion and

  • @nadiaai530 @meAsifAi @ChatGPT This is seriously production-ready, the consistency across every angle and expression is impressive
  • @itsshara_ai @meAsifAi @ChatGPT Reference sheets are what keep a character consistent.
