Trellis2-Rocm-Windows-Installer for https://github.com/visualbruno/ComfyUI-Trellis2

One-click installers for Microsoft TRELLIS 2 on AMD GPUs under Windows — native ROCm build. Includes a portable ComfyUI installer, a global-python installer, all with auto node-clone, force-reinstall wheel installs, and the uv_raster AMD-native rasterizer patches for render/extract.

You need to have access to facebook dinov3 models in order to use Trellis.2

https://huggingface.co/facebook/dinov3-vitl16-pretrain-lvd1689m

Clone the repository in ComfyUI models folder under "facebook/dinov3-vitl16-pretrain-lvd1689m"

So in ComfyUI/models/facebook/dinov3-vitl16-pretrain-lvd1689m

As of now Pixal3D-T model, isnt working. Natten package still needs porting.

Tested on RDNA 4. Compiled with RDNA3, RDNA3.5 and RDNA4 for Rocm 7.2.1+Pytorch 2.9.1 and Rocm 7.14+Pytorch 2.12

Backend needs to be change from Flash Attention--->SDPA as per photo to work

---

3DGenStudio 2.7.1 added SDPA Backend to workflow

As of that version you can use 3DGenStudio with this Wheels.

install-trellis2-portable.bat

Place the .bat and the Trellis 2 Wheels\ folder in the ComfyUI_windows_portable ROOT — the folder containing python_embeded\python.exe and ComfyUI\custom_nodes\. The wheels\ folder must be next to the .bat (same root), and python_embeded\python.exe is detected automatically because the bat checks for it first. If absent, the ComfyUI-Trellis2 node is auto-cloned into ComfyUI\custom_nodes\ and its requirements.txt is installed. git must be on PATH, and wheels are always force-reinstalled, so re-running applies the bundled build cleanly.

install-trellis2-global.bat

Place the .bat next to a Trellis 2 Wheels\ folder (anywhere, since it uses the global python from PATH). The node is cloned into .\ComfyUI\custom_nodes\ComfyUI-Trellis2 (or .\custom_nodes\ if that exists) relative to wherever you run the bat — so run it from the ComfyUI install root if you want the node in the right place. git must be on PATH, and wheels are always force-reinstalled.
