ComfyUI-Pixal3D

ComfyUI custom node for Pixal3D — Tencent's SIGGRAPH 2026 single-image to PBR-textured-3D pipeline — on Windows with RTX 30/40/50 GPUs. Runs standalone in ComfyUI's main Python (no extra worker env needed); optionally piggybacks on ComfyUI-TRELLIS2's pixi env if you already have it.

One image → textured PBR mesh in ~3-5 min on an RTX 5090.

Will it work on my machine?

Short version: if you're on ComfyUI Desktop with an RTX 30/40/50 (Python 3.12 + Torch 2.8 + CUDA 12.8 — the Desktop defaults), this will work standalone.

	Requirement
OS	Windows 10 / 11 (x64) — bundled natten wheel is Windows-only
GPU	NVIDIA RTX 30 / 40 / 50 with ≥ 16 GB VRAM (24 GB+ recommended; the bundled workflows ship with `1024_cascade` + 16/16/16 steps, see the Note node in each for low-VRAM tweaks)
Disk	~50 GB free (24 GB Pixal3D + 4 GB other models + workspace)
CPU	Any modern x86_64 — Intel and AMD both work, no special requirements
Python	3.12 only (ComfyUI Desktop's `.venv` is 3.12 — bundled wheel is cp312)
PyTorch	2.8.x + CUDA 12.8 (Desktop's `.venv` matches by default — wheel is built against torch 2.8.0+cu128)
ComfyUI	Desktop (or portable). ComfyUI-TRELLIS2 is optional — if installed, the installer drops deps into TRELLIS2's pixi env; otherwise it installs into ComfyUI's `.venv`.

Will the wheel work for me?

The bundled wheels/natten-0.21.0+winsm89ptx-...-win_amd64.whl is locked to Windows + Python 3.12 + PyTorch 2.8 + CUDA 12.8 + NVIDIA GPU. If your setup matches all of the above (which the standard ComfyUI-TRELLIS2 pixi env does), the wheel just works.

If any one of those doesn't match (you'
