Houdini - ComfyUI Bridge

The Houdini-ComfyUI Bridge is a plugin that brings the complete ComfyUI node ecosystem directly into Houdini's Copernicus (COPs) framework. It provides building blocks for creating hybrid CG-AI pipelines by mixing Houdini's procedural tools with state-of-the-art generative AI through diffusion architecture. You build ComfyUI graphs inside Houdini's familiar interface, automatically exchanging data between your 3D scene and AI models.

ComfyUI runs as a Python server locally, on your network, or in the GridMarkets cloud. The Bridge communicates with ComfyUI's API, replicating its nodes and workflows as native Houdini nodes inside a special Compound Graph context. You can access all ComfyUI nodes, pipe Houdini data directly into AI workflows, and get results back without leaving your DCC. A single button press synchronizes all available nodes from your ComfyUI installation.

Though you can run ComfyUI locally, GridMarkets provides powerful GPUs in the cloud. Your local machine just needs to run Houdini.

Stable Diffusion checkpoints, ControlNet models, WAN 2.1 for video, Hunyan3D for 3D generation, SEED-VR for upscaling, and many more. New models will be added regularly.

Yes - processing happens on GridMarkets’ secure infrastructure. You can also run entirely locally or on isolated networks if required.

The bridge is actively developed with input from beta testers at major studios. Many workflows are production-functional, with new features added regularly.

The bridge is model-agnostic, so you choose which models to use. As ethically-sourced models become available, they work immediately with no changes needed.

Because it puts cutting-edge generative AI directly into your hands without forcing you to become an AI specialist. This bridge lets you leverage state-of-the-art AI while staying in your creative flow.

It transforms AI from a separate tool into an extension of your creative process. Instead of hoping for good results from a black box, you can iterate rapidly, use Houdini's procedural power to drive AI inputs, and maintain artistic control throughout. Artists describe it as "merging deterministic and non-deterministic tools" for unprecedented creative possibilities.

Everything ComfyUI supports: images, videos, 3D meshes, textures, audio, and more. Specific capabilities include: • Text-to-image generation • Image-to-video with control nets • AI upscaling - SEED-VR, etc. • 3D model generation from images - Hunyan3D, etc. • Texture projection • LLM integration for automated asset labeling
