VAEDecodeHunyuan3D - ComfyUI Built-in Node Documentation - ComfyUI

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. Advanced parameter (default: 8000)	INT	Yes	1000-500000
`octree_resolution`	The resolution of the octree structure used for 3D voxel generation. Advanced parameter (default: 256)	INT	Yes	16-512

Outputs

Output Name	Description	Data Type
`voxels`	The generated 3D voxel data from the decoded latent representation	VOXEL
