The SamplingPercentToSigma node converts a sampling percentage value to a corresponding sigma value using the model’s sampling parameters. It takes a percentage value between 0.0 and 1.0 and maps it to the appropriate sigma value in the model’s noise schedule, with options to return either the calculated sigma or the actual maximum/minimum sigma values at the boundaries.

Inputs

Parameter	Data Type	Required	Range	Description
`model`	MODEL	Yes	-	The model containing the sampling parameters used for conversion
`sampling_percent`	FLOAT	Yes	0.0 to 1.0	The sampling percentage to convert to sigma (default: 0.0)
`return_actual_sigma`	BOOLEAN	Yes	-	Return the actual sigma value instead of the value used for interval checks. This only affects results at 0.0 and 1.0. (default: False)

Outputs

Output Name	Data Type	Description
`sigma_value`	FLOAT	The converted sigma value corresponding to the input sampling percentage
