Poseable Human Workflow with Flux Text-to-Image Model

AI Tool(s) Used

• Flux: A text-to-image model developed by Black Forest Labs, known for its high quality and precision in handling facial and hand details.
• Blender: For creating 3D models and integrating a Mixamo rig.
• Playbook 3D: For single-prompt retexturing.
• ComfyUI: To refine and upscale outputs from Flux.

Description of Result

This workflow demonstrates the creation of poseable human models using a combination of text-to-image AI and 3D modeling software. The process employs a Mixamo rig in Blender to set up a customizable character, which is retextured using Playbook 3D. Flux is used as the primary text-to-image tool, enhancing the model with fine details, particularly in hands and faces, often difficult areas in AI-generated images. Finally, ComfyUI refines and upscales the image, resulting in high-quality visuals ready for animation or traditional media use.

Step-by-Step Breakdown

1. 3D Model Setup: A character model with a Mixamo rig is created in Blender, allowing for customizable poses and animations.
2. Texturing with Playbook 3D: The model is textured using a single prompt in Playbook 3D, adding detail and realism.
3. Image Generation with Flux: Flux is used to generate high-quality textures and fine-tune the character, especially enhancing facial and hand details.
4. Upscaling with ComfyUI: ComfyUI processes the output from Flux, providing final upscale and refinement for crisp visuals.
5. Integration with Animation Workflows: The final, refined model is ready for use in animation, with full control over poses and motion, paving the way for creative freedom in character design.

Tips & Tricks

• Use a Mixamo Rig for Flexibility: Setting up a Mixamo rig in Blender provides flexibility, allowing for easy pose adjustments and motion controls.
• Leverage Flux for Detail Work: Flux excels in rendering complex details in hands and faces, so use it for tasks that require a high degree of precision.
• Combine with ComfyUI for Upscaling: Final refinements in ComfyUI help achieve professional-level detail and quality in the final image output.

Annotation

This process exemplifies a groundbreaking workflow for 3D character design by combining traditional 3D rigging with AI text-to-image generation. By using Flux to handle challenging details like hands and faces, the artist achieves a high level of quality in areas typically difficult for AI. This approach showcases how AI can complement traditional animation workflows, expanding creative possibilities and allowing for detailed, poseable characters.
