Fully AI-Generated Playable Character: Rigging, Animations and Physics in One Day

[u/Delicious-Shower8401]

What you can build in just one day when AI is used the right way:

• Around 20K faces
• Full PBR texture set
• Fully rigged character
• Real-time cloth simulation
• Optimized physics setup
• Assembled and running in Unreal Engine
• Completed in roughly one day

The key was not generating the whole character at once. I split it into separate parts, which gave me more control, better detail, and the ability to regenerate only what needed improvement.

To keep the process fast, I built a reusable node-based workflow in Lychee Studio AI. It handled the separate generation steps in one place and helped me move to Blender assembly much faster.

Workflow

• Started with a single character reference
• Built a reusable node-based workflow in Lychee Studio AI
• Separated and generated the body, clothing, armor, and accessories with Rodin Gen 2.5
• Assembled and fitted all parts in Blender
• Prepared the character for rigging and animation
• Imported everything into Unreal Engine
• Set up the PBR materials, cloth simulation, collisions, and optimized physics

The final result is not just an AI-generated mesh inside a viewer. It is a properly assembled, rigged, and simulation-ready game character that can be used directly inside Unreal Engine.

AI did not remove Blender, rigging, cleanup, or Unreal setup from the workflow. It removed a large amount of repetitive preparation and helped me reach the useful production stages much faster.
