The SamplerDPMPP_2S_Ancestral node creates a sampler that uses the DPM++ 2S Ancestral sampling method for generating images. This sampler combines deterministic and stochastic elements to produce varied results while maintaining some consistency. It allows you to control the randomness and noise levels during the sampling process.

Inputs

Parameter	Data Type	Required	Range	Description
eta	FLOAT	Yes	0.0 - 100.0	Controls the amount of stochastic noise added during sampling (default: 1.0)
s_noise	FLOAT	Yes	0.0 - 100.0	Controls the scale of noise applied during the sampling process (default: 1.0)

Outputs

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