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

Outputs

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