Inputs (20)

Name	Type	Default	Description
sigmas_presetopt	COMBO	custom	Load a saved sigma-shape recipe into the panel for this run. 'custom' = use the panel as-is. Use the ★ Save Preset button to add one; the list refreshes on graph reload.
s1_enableopt	BOOLEAN	true	When ON, S1 uses this curve and OVERRIDES the Ultra node's s1_schedule dropdown. When OFF, S1 falls back to that dropdown (mix authored + panel stages).
s1_curveopt	COMBO	beta57	S1 sigma spacing. linear=composition; balanced/karras=more low-sigma detail; beta57/beta=RES4LYF beta spacing; bong_tangent=hold-then-drop; exponential=geometric.
s1_detail_biasopt	FLOAT	0.00-1–1	S1 detail vs composition (-1..+1). >0 packs steps at low sigma (fine detail); <0 favours high sigma (structure). Works on every curve (Karras rho / bong_tangent slope, or a step redistribution otherwise).
s1_rhoopt	FLOAT	0.00–30	S1 advanced: explicit Karras rho for balanced/karras curves. 0 = auto (derived from detail_bias). Higher = more low-sigma concentration.
s1_alphaopt	FLOAT	0.500.05–6	S1 advanced: Beta-distribution alpha (only the 'beta' curve). beta57 is fixed alpha=0.5.
s1_betaopt	FLOAT	0.700.05–6	S1 advanced: Beta-distribution beta (only the 'beta' curve). beta57 is fixed beta=0.7.
s2_enableopt	BOOLEAN	true	When ON, S2 uses this curve and OVERRIDES the Ultra node's s2_schedule dropdown. When OFF, S2 falls back to that dropdown (mix authored + panel stages).
s2_curveopt	COMBO	linear	S2 sigma spacing. linear=composition; balanced/karras=more low-sigma detail; beta57/beta=RES4LYF beta spacing; bong_tangent=hold-then-drop; exponential=geometric.
s2_detail_biasopt	FLOAT	0.00-1–1	S2 detail vs composition (-1..+1). >0 packs steps at low sigma (fine detail); <0 favours high sigma (structure). Works on every curve (Karras rho / bong_tangent slope, or a step redistribution otherwise).
s2_rhoopt	FLOAT	0.00–30	S2 advanced: explicit Karras rho for balanced/karras curves. 0 = auto (derived from detail_bias). Higher = more low-sigma concentration.
s2_alphaopt	FLOAT	0.500.05–6	S2 advanced: Beta-distribution alpha (only the 'beta' curve). beta57 is fixed alpha=0.5.
s2_betaopt	FLOAT	0.700.05–6	S2 advanced: Beta-distribution beta (only the 'beta' curve). beta57 is fixed beta=0.7.
s3_enableopt	BOOLEAN	true	When ON, S3 uses this curve and OVERRIDES the Ultra node's s3_schedule dropdown. When OFF, S3 falls back to that dropdown (mix authored + panel stages).
s3_curveopt	COMBO	linear	S3 sigma spacing. linear=composition; balanced/karras=more low-sigma detail; beta57/beta=RES4LYF beta spacing; bong_tangent=hold-then-drop; exponential=geometric.
s3_detail_biasopt	FLOAT	0.00-1–1	S3 detail vs composition (-1..+1). >0 packs steps at low sigma (fine detail); <0 favours high sigma (structure). Works on every curve (Karras rho / bong_tangent slope, or a step redistribution otherwise).
s3_rhoopt	FLOAT	0.00–30	S3 advanced: explicit Karras rho for balanced/karras curves. 0 = auto (derived from detail_bias). Higher = more low-sigma concentration.
s3_alphaopt	FLOAT	0.500.05–6	S3 advanced: Beta-distribution alpha (only the 'beta' curve). beta57 is fixed alpha=0.5.
s3_betaopt	FLOAT	0.700.05–6	S3 advanced: Beta-distribution beta (only the 'beta' curve). beta57 is fixed beta=0.7.
preset_notesopt	STRING		One or two sentences: what this curve is FOR (which sampler / recipe) and what it does. Saved and loaded with the ★ preset.
