Hunyuan3D-2.1 MLX Weights

Pre-converted MLX weights for the Hunyuan3D-2.1 texture generation (paint) pipeline, optimized for Apple Silicon Macs.

These weights provide ~3-5x faster UNet inference compared to the PyTorch MPS backend.

Files

unet.npz	~3.9 GB	MLX UNet weights (Conv2d transposed NCHW→NHWC, GeGLU split)
vae.npz	~335 MB	MLX VAE encoder/decoder weights

Source

Converted from tencent/Hunyuan3D-2.1 (hunyuan3d-paintpbr-v2-1/) using the weight conversion tool in ComfyUI-Hunyuan3d-Paint.

Usage

Download both files and place in your ComfyUI models directory:

ComfyUI/models/diffusers/hunyuan3d-mlx-weights/
├── unet.npz
└── vae.npz

Then select mlx in the diffusion_backend dropdown of the MultiViews Generator node.

Requires ComfyUI-Hunyuan3d-Paint with MLX installed (pip install mlx).
