Inputs
| Input | Type | Required | Default | Meaning |
|---|---|---|---|---|
| in | Image | Required | — | See the overview for the node's documented behavior. |
Properties
| Property | Type | Default | Animatable | Range / options | Effect |
|---|---|---|---|---|---|
| Source Channel | Enum | Luminance | Not declared | Luminance · Alpha · Red · Green · Blue | Selects the source channel behavior; each option changes the operation described in the overview. |
| Output Min | Scalar | 0 | Yes | Hard 0..1 · Step .01 | Animatable control; changing it over time varies the node response. |
| Output Max | Scalar | 1 | Yes | Hard 0..1 · Step .01 | Animatable control; changing it over time varies the node response. |
| Invert | Bool | false | Not declared | — | Local control documented by the production node behavior. |
Outputs
| Output | Type | Meaning |
|---|---|---|
| out | Image | The production node output described by the overview. |
Usage
In practice
- Use Normalize / Auto Range when a source occupies only part of the available tonal range.
- Choose the source channel, set the output endpoints, and invert only when the downstream mask needs the opposite polarity.
Notes / limitations
- The node measures the input range before rescaling it; it is a general image filter, not a Material-only node.
