SplitSigmasDenoise - ComfyUI Built-in Node Documentation

The SplitSigmasDenoise node divides a sequence of sigma values into two parts based on a denoising strength parameter. It splits the input sigmas into high and low sigma sequences, where the split point is determined by multiplying the total steps by the denoise factor. This allows for separating the noise schedule into different intensity ranges for specialized processing.

Inputs

Parameter	Description	Data Type	Required	Range
`sigmas`	The input sequence of sigma values representing the noise schedule	SIGMAS	Yes	-
`denoise`	The denoising strength factor that determines where to split the sigma sequence (default: 1.0)	FLOAT	Yes	0.0 - 1.0 (step: 0.01)

Outputs

Output Name	Description	Data Type
`high_sigmas`	The first portion of the sigma sequence containing higher sigma values	SIGMAS
`low_sigmas`	The second portion of the sigma sequence containing lower sigma values	SIGMAS
