Inputs (20)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| positive | CONDITIONING | SCENE prompt (or your only prompt) | |
| latent_image | LATENT | At the final resolution (⚗ Resolution node) | |
| seed | INT | 00–18446744073709550000 | BASE seed. With previews keep it on 'fixed' |
| profilo | COMBO | (auto) = profile calibrated on this model at the closest resolution | |
| modo | COMBO | equilibrato | 3 options: veloce, equilibrato, massimo dettaglio |
| due_stadi | BOOLEAN | true | — |
| ridisegno | FLOAT | -1.00-1–0.95 | Hand-off sigma between the two stages. -1 = from the profile |
| dettaglio | FLOAT | 0.120–0.25 | Micro-relief. 0.12 validated; above 0.2 coloured speckles come back |
| varieta | FLOAT | 0.600–1.2 | Noise that creates texture. 0 = deterministic |
| denoise | FLOAT | 1.000–1 | 1.0 = from scratch. <1 = img2img (no two stages, no previews) |
| cambio_fase | FLOAT | -1.00-1–0.99 | Sigma below which the DETAIL prompt takes over. -1 = where composition is locked (from the profile, ~0.87). Lower = detail weighs less. 0 = off. Acts on skin, fabric, patterns, small objects; NOT on colours or global style (measured: those are decided in the first step together with composition) |
| sfumatura | FLOAT | 0.000–0.4 | Width of the cross-fade between the two prompts. 0 = hard switch (no cost). >0 = gradual blend, costs one extra model call per step inside the band |
| anteprime | INT | 00–16 | N > 0: generates N low-resolution previews (seed, seed+1, ...), up to ~30 s each. Measured: pose and framing match the final image (0.87-0.90); clothing may change. Then set 0 again and pick the number in 'scelta' (choice) |
| scelta | INT | 00–255 | With previews = 0: completes preview number k (uses seed + k) |
| variante_rifinitura | INT | 00–9999 | Changes ONLY the second-stage noise: same pose and framing, but face, lettering, jewellery and small objects change. 0 = standard |
| positive_dettaglioopt | CONDITIONING | DETAIL prompt (from the ⚗ Two-phase prompt or ⚗ Text node). Disconnected = behaves like AlchemicaKrea | |
| negativeopt | CONDITIONING | — | |
| modello_rifinituraopt | MODEL | Stage 2 with a different model | |
| optsopt | ALCHEMICA_OPTS | — |
