How To Create Multiple AI Characters In One Scene
TLDRIn this tutorial, the speaker demonstrates how to create a scene with multiple AI characters without merging their traits, which is a common issue when generating images of characters together. The process involves using a canvas to compose the scene with a background and three characters, removing backgrounds, adjusting sizes, and ensuring proper lighting. The technique also includes duplicating the scene, manually adjusting character positions, and using image-to-image adjustments to achieve consistent lighting and details. The video concludes with tips on manual upscaling to improve details without affecting the original composition and the announcement of an upcoming update to the platform.
Takeaways
- 🎨 **Create Separate Assets**: Start by having a background and individual characters as separate elements to avoid merging issues when combining characters.
- 🖼️ **Remove Backgrounds**: Use the remove background feature to isolate characters for easier composition in the scene.
- 🔄 **Duplicate Scene**: Duplicate the scene and manually adjust the size of characters to fit the composition.
- 👥 **Character Positioning**: Position characters in a way that makes sense within the scene, considering their size and interaction with the environment.
- 🌄 **Adjust Lighting**: Address differences in lighting between characters and the background by using the image-to-image feature with a sunset lighting prompt.
- 🔍 **Image Strength**: Experiment with image strength (45-50) to find the right balance between the original composition and the new lighting.
- 📏 **Manual Upscaling**: Perform a manual upscale by cropping individual characters and using image-to-image to enhance details without affecting the entire composition.
- ✂️ **Crop Carefully**: When cropping, ensure to include shadows and details to maintain the integrity of the character in the final scene.
- 🔄 **Iterative Process**: Use an iterative approach to refine the image, regenerating areas that need improvement and using in-painting to fix any seams.
- 🧩 **Compose Final Scene**: Once individual character details are refined, compose the final scene by aligning and adjusting the new assets.
- ⚙️ **Control Your Composition**: This method, while time-consuming, allows for greater control over the final scene, ensuring the desired characters and elements are included.
Q & A
What is the main challenge when trying to generate an image of two distinct AI characters in one scene?
-The main challenge is that the AI might merge the characters, causing them to share traits from each other's costumes, which doesn't work well. This is a current limitation of the models.
Why is it recommended to keep the original character assets when starting the composition process?
-It is advised to keep the originals in case things go wrong or if you need to start over, ensuring you have a backup to return to.
How can one remove the background from the character images during the composition process?
-One can select each image and use tools within the canvas to remove the background, ensuring a clear separation between the characters and the background.
What is the purpose of duplicating the scene and manually adjusting the characters' positions?
-The purpose is to compose the scene with the desired arrangement of characters, adjusting their sizes and positions to create a coherent and visually appealing final image.
Why is image-to-image upscaling used to adjust the lighting in the composed scene?
-Image-to-image upscaling is used to apply consistent lighting across all subjects in the scene, which may otherwise have different lighting due to their original images.
What is the recommended image strength value for starting the image-to-image process?
-A good starting point for image strength is between 45 to 50, though it may be adjusted based on the specific needs of the composition.
How can one manually upscale individual character images to improve details?
-One can crop each character tightly, ensuring not to crop out important details like shadows, and then use image-to-image upscaling to increase the size and pull more details from the image.
Why is it important to include the subject in the prompt when using image-to-image upscaling?
-Including the subject in the prompt helps the AI to focus on the specific character or element being upscaled, ensuring that the generated image retains the desired details and characteristics.
What is the benefit of using a tight crop when upscaling individual character images?
-A tight crop helps to maintain the original composition and details of the character while allowing for an increase in size without significantly altering the background or other non-subject elements.
How can one fix areas in the upscaled image that do not blend well with the background?
-One can use the eraser tool to remove the blurry or mismatched areas and then use the in-painting feature to regenerate a seamless blend with the background.
What is the advantage of the described method for creating a scene with multiple AI characters?
-The advantage is the ability to control the scene composition, lighting, and character details, allowing for a more precise and customized final image, despite the limitations of current AI models.
What is Playground V3 and how does it relate to the discussed composition process?
-Playground V3 is an upcoming update that combines the functionalities of Canvas and Board into a new user interface. It is expected to change the UI but maintain the same tools and concepts, which will still be applicable to the discussed composition process.

🎨 Composing a Scene with Multiple Characters
The video begins with the host introducing a method to create a scene with multiple characters without merging their traits, which is a current limitation of AI models. The process involves using a canvas tool to compose the scene with a background and three separate character images. The host advises keeping the original images as a backup. Each character's background is removed, and the scene is composed by adjusting the size and position of the characters to create a narrative. The lighting is then harmonized across the scene using an 'image to image' feature with a sunset lighting effect. The host emphasizes the importance of starting with a comfortable familiarity with the canvas tool.
🖌️ Manual Upscaling and Detail Tweaking
The host demonstrates how to manually upscale individual character images while maintaining the original composition. This process involves cropping the characters tightly, ensuring shadows are retained, and then using the 'image to image' feature to upscale and enhance details. The image strength is adjusted for each character to achieve the desired level of detail. The host also explains the importance of including the subject in the prompt during the upscaling process to maintain consistency. After upscaling, the characters are re-integrated into the scene, with attention given to aligning them properly and addressing any inconsistencies in the background.
🔍 Final Scene Composition and Future Updates
The video concludes with the host discussing the final composition of the scene, emphasizing the control and customization achieved through the process. The host also mentions the potential for creative upscaling and shows a comparison between the upscaled and original images. They highlight the improved blending of lighting and details in the upscaled version. Additionally, the host teases upcoming changes with the development of Playground V3, which will feature a new UI combining canvas and board functionalities. They also reference other videos that cover utilizing drawings to further control and condition images.
