Overview
Per-hue correction curves — desaturate just the greens, darken just the blues. The spill-and-sky tool.
How to
How-to
- Pick a curve (saturation, luminance, red…) and pull it down or up at the hue you want to change.
- The curves are indexed by hue: for a selection that also depends on saturation and brightness use BS_HueQualifier or BS_MasterColor's Hue vs page.
- Sample the viewer with the eyedropper to add a point at the sampled hue.
Inputs
| Input | What it takes |
|---|---|
| in | the image this node works on |
| mask | limits the effect to this matte — the engine's universal mask slot, applied for every node that declares it |
Outputs
| Output | Type |
|---|---|
| out | Image |
Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| channels | Choice | rgba | Which channels this node writes: rgba, rgb (alpha passes through untouched), alpha only, all, or none (bypass). Everything unselected comes straight from the input — same as Nuke. allrgbargbalphanone |
| sat | Lut | 7 points | Saturation per hue: pull the point over a hue to desaturate it. |
| lum | Lut | 7 points | Luminance per hue. |
| red | Lut | 7 points | The channel's gain per hue. |
| green | Lut | 7 points | The channel's gain per hue. |
| blue | Lut | 7 points | The channel's gain per hue. |
| r_sup | Lut | 7 points | Suppression: the channel pulled DOWN toward the other two per hue — spill removal by hue. |
| g_sup | Lut | 7 points | Suppression: the channel pulled DOWN toward the other two per hue — spill removal by hue. |
| b_sup | Lut | 7 points | Suppression: the channel pulled DOWN toward the other two per hue — spill removal by hue. |
| sat_thrsh | Lut | 7 points | Below this saturation a hue's corrections fade out, so greys are left alone. |
| mix_luminance | Float | 1.0 | How much the luminance curve applies. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. | |
| hide_input | Bool | false | Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap). |
