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

Outputs

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