ChannelRoute
Compv2coreConcat: Pointwise
Overview
The channel patch bay: route any layer's channels — from either input — into any output layer. Constants 0/1 fill; typing a new output layer declares it. Wiring, not math.
How to
How-to
- Pick the output layer, then for each of r, g, b, a choose the source channel by name (
diffuse.r,rgba.a, or a constant 0 / 1). - The patch bay in the panel is the same thing drawn as wires.
- Use it to lift one AOV into rgba, or to build an alpha from a data pass.

Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| out_layer | Text | rgba | The layer this node writes. |
| r | Text | rgba.r | Which input channel (layer.channel) feeds this output channel — or a constant 0/1. |
| g | Text | rgba.g | Which input channel (layer.channel) feeds this output channel — or a constant 0/1. |
| b | Text | rgba.b | Which input channel (layer.channel) feeds this output channel — or a constant 0/1. |
| a | Text | rgba.a | Which input channel (layer.channel) feeds this output channel — or a constant 0/1. |
| c5 | Text | 0 | Extra output channels for layers wider than four — a constant 0 leaves them off. |
| c6 | Text | 0 | Extra output channels for layers wider than four — a constant 0 leaves them off. |
| c7 | Text | 0 | Extra output channels for layers wider than four — a constant 0 leaves them off. |
| c8 | Text | 0 | Extra output channels for layers wider than four — a constant 0 leaves them off. |
| 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). |
