Inputs (10)

NameTypeDefaultDescription
momentumFLOAT0.950-0.5–2.5How much of the normal result to keep during sampling. 0.95 means 95% normal, 5% from history. When set to 1.0 effectively disables momentum.
momentum_histFLOAT0.750-1.5–1.5How much of the existing history to leave at each update. 0.75 means keep 75%, mix in 25% of the new result.
momentum_initCOMBOZEROInitial value used for momentum history. ZERO - history starts zeroed out. RAND - History is initialized with a random value. SAMPLE - History is initialized from the latent at the start of sampling.
directionFLOAT1.000-30–15Multiplier applied to the result of normal sampling.
rand_init_noise_typeCOMBOgaussianNoise type to use when momentum_init is set to RANDOM.
s_noiseFLOAT1.000-10000–10000Multiplier for noise added during ancestral or SDE sampling.
etaFLOAT1.000-10000–10000Basically controls the ancestralness of the sampler. When set to 0, you will get a non-ancestral (or SDE) sampler.
noise_typeCOMBObrownianSets the type of noise.
guidance_cfg_optoptSONAR_GUIDANCE_CFGOptional input for extended guidance parameters.
custom_noise_optoptSONAR_CUSTOM_NOISE,OCS_NOISEOptional input for custom noise used during ancestral or SDE sampling. When connected, the built-in noise_type selector is ignored. The following input types are supported: SONAR_CUSTOM_NOISE, OCS_NOISE
