VAEDecodeHunyuan3D - ComfyUI Built-in Node Documentation

Complete documentation for the VAEDecodeHunyuan3D node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The VAEDecodeHunyuan3D node converts latent representations into 3D voxel data using a VAE decoder. It processes the latent samples through the VAE model with configurable chunking and resolution settings to generate volumetric data suitable for 3D applications.

Inputs

Parameter	Description	Data Type	Required	Range
samples	The latent representation to be decoded into 3D voxel data	LATENT	Yes	-
vae	The VAE model used for decoding the latent samples	VAE	Yes	-
num_chunks	The number of chunks to split the processing into for memory management (default: 8000)	INT	Yes	1000-500000
octree_resolution	The resolution of the octree structure used for 3D voxel generation (default: 256)	INT	Yes	16-512
