The SamplerLCMUpscale node provides a specialized sampling method that combines Latent Consistency Model (LCM) sampling with image upscaling capabilities. It allows you to upscale images during the sampling process using various interpolation methods, making it useful for generating higher resolution outputs while maintaining image quality.

Inputs

Parameter	Data Type	Required	Range	Description
`scale_ratio`	FLOAT	No	0.1 - 20.0	The scaling factor to apply during upscaling (default: 1.0)
`scale_steps`	INT	No	-1 - 1000	The number of steps to use for upscaling process. Use -1 for automatic calculation (default: -1)
`upscale_method`	COMBO	Yes	”bislerp" "nearest-exact" "bilinear" "area" "bicubic”	The interpolation method used for upscaling the image

Outputs

Output Name	Data Type	Description
`sampler`	SAMPLER	Returns a configured sampler object that can be used in the sampling pipeline
