ManualSigmas - ComfyUI Built-in Node Documentation

Complete documentation for the ManualSigmas node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ManualSigmas node allows you to manually define a custom sequence of noise levels (sigmas) for the sampling process. You input a list of numbers as a string, and the node converts them into a tensor that can be used by other sampling nodes. This is useful for testing or creating specific noise schedules.

Inputs

Parameter	Description	Data Type	Required	Range
sigmas	A string containing the sigma values. The node will extract all numbers from this string. For example, “1, 0.5, 0.1” or “1 0.5 0.1”. The default value is “1, 0.5”.	STRING	Yes	Any comma or space-separated numbers

Outputs

Output Name	Description	Data Type
sigmas	The tensor containing the sequence of sigma values extracted from the input string.	SIGMAS
