Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | — | |
| grain_size | FLOAT | 1.200.7–4 | Grain radius in pixels at a 1024px reference. Scaled with image size so grain stays a fixed fraction of the frame at any resolution. |
| strength | FLOAT | 0.500–1 | Grain intensity. Blends the grainy render with the original (tone is preserved either way). |
| radius_variation | FLOAT | 0.000–0.5 | Grain size variability (sigma/mean). 0 = uniform grains, higher = mixed sizes (log-normal). |
| color_grain | FLOAT | 0.000–1 | 0 = monochrome (luminance) grain, 1 = independent per-channel grain (chroma grain, like color film). |
| seed | INT | 00–4294967295 | Random seed for a reproducible grain pattern. |
| monte_carlo_samplesopt | INT | 648–256 | Render quality. Higher = cleaner estimate (grain is preserved), but slower. Cost is linear in this. |
| filter_sigmaopt | FLOAT | 0.80.4–2 | Grain softness (Gaussian filter sigma in output pixels). 0.8 is the physically-motivated default. |
