The Flux2Scheduler node generates a sequence of noise levels (sigmas) for the denoising process, specifically tailored for the Flux model. It calculates a schedule based on the number of denoising steps and the dimensions of the target image, which influences the progression of noise removal during image generation.

Inputs

Parameter	Data Type	Required	Range	Description
steps	INT	Yes	1 to 4096	The number of denoising steps to perform. A higher value typically leads to more detailed results but takes longer to process (default: 20).
width	INT	Yes	16 to 16384	The width of the image to be generated, in pixels. This value influences the noise schedule calculation (default: 1024).
height	INT	Yes	16 to 16384	The height of the image to be generated, in pixels. This value influences the noise schedule calculation (default: 1024).

Outputs

Output Name	Data Type	Description
sigmas	SIGMAS	A sequence of noise level values (sigmas) that define the denoising schedule for the sampler.
