Trellis 2 - 3D Asset Generation - ComfyUI One Click Installer

Generate high-resolution 3D mesh assets directly inside ComfyUI with the open-source Microsoft Trellis 2 3D model!
Trellis 2 is Microsoft's latest state-of-the-art 3D generation model, building on the original Trellis with major improvements in both quality and efficiency. Compared to its predecessor, Trellis 2 offers sharper object contours, more consistent texture mapping, and improved generalization across a wider variety of object types. It also handles transparency and occlusions more effectively, making it ideal for asset creators, game developers, and digital artists who want ultra-fast, high-fidelity 3D reconstruction.
My included One-Click ComfyUI Windows Installer simplifies setup by automatically downloading and configuring all required dependencies, models, and custom nodes. No manual setup or command-line work needed — just install, run, and start generating 3D assets within minutes.

Usage Notes
Use ComfyUI Manager's Install missing custom nodes feature for any nodes that don't install automatically.
To generate your own 3D assets, upload a transparent-background image of the object you want to recreate, then run the Trellis 2 workflow. A background removal workflow is included.
If you encounter out-of-memory errors, restart the workflow and reduce the guidance strength settings.
The ComfyUI node for Trellis 2 is still actively developed — check the GitHub repository for the latest updates and bug fixes.
