⬡ Polyhedron Sigma Curve
Universal sigma-curve for any model. Set sigma_max/sigma_min to match your model family. Wire the 'steps' output to samplers and schedulers for single-point sync.

Inputs (5)
| Name | Type | Default | Description |
|---|---|---|---|
| sigma_schedule | COMBO | karras | Sigma curve shape — affects how steps are distributed across the noise range |
| steps | INT | 201–300 | Number of steps. Also passed through as output for downstream sync. |
| sigma_max | FLOAT | 1.0000.0001–1000 | Flow-matching (WAN/FLUX/SD3): 1.0 — k-diffusion (SDXL/SD1.5): 14.61 |
| sigma_min | FLOAT | 0.00200.00001–100 | Flow-matching (WAN/FLUX/SD3): 0.002 — k-diffusion (SDXL/SD1.5): 0.029 |
| rho | FLOAT | 7.00.1–20 | Shape param — only affects karras, exponential, laplace |
