TripoSplatSamplingPreview - ComfyUI Built-in Node Documentation

This node patches a TripoSplat model so that when used with the standard KSampler node, a live preview of the decoded gaussian splat is shown at each sampling step. It works by wrapping the sampler’s callback to decode the model’s output into a preview image after every step.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The TripoSplat model to patch for live preview	MODEL	Yes
`vae`	TripoSplat VAE decoder	VAE	Yes
`octree_level`	Octree depth for the preview decode (lower = cheaper/coarser). Default: 5	INT	No	2 to 8
`num_gaussians`	Number of gaussians to produce for the preview (rounded to a multiple of 32). Default: 16384	INT	No	1024 to 262144 (step: 32)
`yaw`	Preview camera yaw in degrees. Default: 90.0	FLOAT	No	-360.0 to 360.0 (step: 1.0)
`pitch`	Preview camera pitch in degrees. Default: 15.0	FLOAT	No	-89.0 to 89.0 (step: 1.0)
`point_size`	Maximum splat radius in pixels. Each gaussian is sized from its scale and capped here; lower = finer/pointier, higher = chunkier. Default: 3	INT	No	1 to 16

Outputs
