When we render double-character scenes on the ReadKidz storyboard page, we often encounter a series of problems such as the characters merging together, lack of interaction between characters, and chaotic character features!

How should we fine-tune the dual-character scene to achieve satisfactory picture book production? In fact, we just need to modify the two-person scene into a single-person scene, which will not affect the structure and integrity of the entire story! **Step 1 :** After entering the PPT page, review the picture book subtitles, as well as the especially important placeholder images! What is a placeholder image? It is the character portrait created when creating a character, and by selecting the corresponding character portrait based on the prompt words and subtitles, you can consistently generate illustrations with that character! Therefore, the selection and deletion of placeholder images play a crucial role in the image!

**Step 2 :** Find the subtitles for the corresponding two-person scenes, and click “AI Images” to enter the image generation page!

**Step 3 :** We will extract the keywords and divide them according to a certain format!

**Step 4 :** Then, based on the subtitle's corresponding story scene, keep the important character! For example："But remember," said the Fairy Godmother, "you must be home before the clock strikes midnight!" We only need to keep the character "Fairy Godmother"! Then we need to adjust the original prompt format! 1.Delete the number of people in the scene, the description of the actions of the two characters, and the character information of the character "Cinderella"! 2.The atmosphere in the space-time description must not contain interactive prompt words! 3.Character information prompt left cannot have any prompts that interact with other characters! Note: Be sure to add "solo" at the beginning of the character information to ensure the stability of single-player scenes!

**Step 5 :** Based on the keywords of the roles, remove the placeholder images of unnecessary roles in “Portrait reference” to generate a stable single-player scene image!
