How Ubisoft Open-Sources the CHORD Model and ComfyUI Nodes for End-to-End PBR Material Generation
Ubisoft open-sourced the CHORD model with custom ComfyUI nodes, enabling end-to-end PBR material generation that streamlines game asset creation across their studios.
End-to-End PBR Material Generation
The CHORD Model and ComfyUI Integration
Ubisoft open-sourced the CHORD model with custom ComfyUI nodes, enabling end-to-end PBR material generation that streamlines game asset creation across their studios.
The integration allows artists to generate physically-based rendering materials directly within ComfyUI, maintaining full control over texture quality and material properties.
"The CHORD model represents a breakthrough in AI-assisted material creation, enabling artists to generate production-quality PBR textures with unprecedented speed and control."

The CHORD model generates complete PBR material sets from simple text descriptions or reference images, dramatically accelerating the material creation process.
By open-sourcing both the model and the ComfyUI integration, Ubisoft has contributed a powerful tool to the game development community.
Open-Source Contribution
Ubisoft's decision to open-source the CHORD model demonstrates the company's commitment to advancing the game development community through shared innovation.
The custom ComfyUI nodes make the CHORD model accessible to any developer or artist, regardless of their technical background.
PBR Pipeline Integration
The CHORD model integrates seamlessly with existing PBR pipelines, generating materials that are immediately usable in modern game engines like Unreal Engine and Unity.
Artists can fine-tune generated materials through the ComfyUI interface, adjusting parameters to match specific art direction requirements.
Cross-Studio Collaboration
The CHORD model and ComfyUI nodes enable consistent material generation across Ubisoft's global network of studios, ensuring unified visual quality.
Shared workflows and configurations mean that teams across the world can produce materials that meet the same quality standards.
Community Impact
Since its release, the CHORD model has been adopted by independent developers and small studios, demonstrating the power of open-source tools in democratizing game development.
The ComfyUI community has built upon the CHORD nodes, creating extended workflows that combine material generation with other AI-assisted tasks.
Future Development
Ubisoft continues to develop and improve the CHORD model, with plans for additional material types and enhanced integration with ComfyUI's evolving ecosystem.
"The CHORD model represents a breakthrough in AI-assisted material creation, enabling artists to generate production-quality PBR textures with unprecedented speed and control."
