The SetFirstSigma node modifies a sequence of sigma values by replacing the first sigma value in the sequence with a custom value. It takes an existing sigma sequence and a new sigma value as inputs, then returns a new sigma sequence where only the first element has been changed while keeping all other sigma values unchanged.

Inputs

Parameter	Data Type	Required	Range	Description
`sigmas`	SIGMAS	Yes	-	The input sequence of sigma values to be modified
`sigma`	FLOAT	Yes	0.0 to 20000.0	The new sigma value to set as the first element in the sequence (default: 136.0)

Outputs

Output Name	Data Type	Description
`sigmas`	SIGMAS	The modified sigma sequence with the first element replaced by the custom sigma value
