AI 3D Model Generation Workflow

Introduction

  • AI-powered 3D model generation has become more advanced.
  • Demonstration of a workflow from AI-generated concept art to a rigged 3D model.
  • Useful for certain types of games and art styles.

Tools and Resources

  • Leonardo AI: Preferred for its real-time generation feature.
    • Allows tweaking sliders for different art styles.
    • Consistent character creation within the same art style.
  • Roden by Hyper Human: Excellent for converting concept art into 3D models.

Steps for Generating 3D Models

1. Concept Art Creation

  • Use Leonardo AI to generate concept art.
    • Find an art style you like and tweak sliders.
    • Remember the settings for consistent character variations.

2. Uploading and Generating 3D Models

  • Upload the concept art to Roden by Hyper Human.
  • Opt for simpler geometry for better results.
  • Generate the model, which includes a preview and allows adjustments (e.g., smooth vs. sharp edges).
  • Toggle settings such as hyper mode for fine details.

3. Refining the 3D Model

  • Initial generation may not be perfect.
  • Adjust the number of polygons for desired quality.
  • Generate texture based on the concept art image.
    • Fine-tuning sliders like complexity and detail in PBR.

4. Exporting the 3D Model

  • Export as FBX format with PBR shading.
  • 4K textures are recommended for better quality.
  • Links to tools and potential affiliate links provided for support.

5. Importing into Unreal Engine

  • Drag and drop the FBX file into Unreal Engine.
  • Create materials manually if automatic import fails.
    • Assign textures to the base color, metallic, normal, and roughness.
  • Assign the created material to the 3D model.
  • Test the model under various lighting conditions.

Summary

  • Workflow from concept art to in-game 3D model demonstrated.
  • Suitable for stylized games, not yet ideal for realistic human characters.

Future Directions

  • Potential video on converting static mesh to skeletal mesh in Unreal Engine.
  • Links to support the channel and additional resources.

Conclusion

  • Encouragement to try AI tools for game development and character creation.
  • Call for feedback and suggestions for future videos.
