ComfyUI Node
Selective Sigma Detailer (Debug)
Debug variant of the SAMPLER node. Exposes the hardcoded constants (schedule start, ema, mask clip percentile) and the mask_ref output so the mask can be inspected via the debug preview node. Defaults match the main node's internal values; change them only to experiment or diagnose unexpected behavior.

Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| sampler | SAMPLER | — | |
| strength | FLOAT | 0.100-1–1 | — |
| coverage | FLOAT | 0.500–1 | — |
| start | FLOAT | 0.100–1 | Fraction of schedule to skip before applying detail. At least 1 step is always skipped. |
| end | FLOAT | 0.900–1 | Fraction of schedule at which the tail taper hits zero. At least 1 step at the end is always clean. |
| ema | FLOAT | 0.900–1 | Temporal mask smoothing. 0 = per-step, higher = stronger carryover across steps. |
| mask_clip_percentile | FLOAT | 0.2000–0.49 | Clip the top/bottom fraction of delta values before min/max stretch. |
| mask_override | COMBO | off | Force the mask to a constant for blend-path diagnostics. 'ones' at coverage<1 should match the coverage=1 fast path; 'zeros' should match baseline; 'half' isolates pure x0 blending. |
