VAEDecodeTripoSplat - ComfyUI Built-in Node Documentation

Decode a TripoSplat latent representation into a 3D gaussian splat. This node takes the sampled latent from a TripoSplat model and reconstructs it as a set of 3D gaussians, which can be adjusted in density by modifying the number of gaussians produced.

Inputs

Parameter	Description	Data Type	Required	Range
`samples`	The latent samples to decode	LATENT	Yes	-
`vae`	TripoSplat VAE decoder model	VAE	Yes	-
`num_gaussians`	Number of gaussians to produce (rounded to a multiple of 32). 262144 matches the octree’s point density; higher oversamples the same points (denser, but no new detail) and costs proportionally more VRAM/time. Default: 262144	INT	Yes	32 to 1048576 (step: 32)
`seed`	Seeds the octree point sampler (global RNG) for deterministic decodes. Default: 0	INT	Yes	0 to 18446744073709551615

Note: The num_gaussians value is automatically rounded to a multiple of the VAE decoder’s gaussians-per-point setting. The actual number used may differ slightly from the input value.
