How to use Channel Process node in Oraphim

Type ID: fusion.channel_process
Category: Color

What this node does

The Channel Process node is registered in Oraphim's Color category and performs the graph operation represented by its sockets and controls below.

The current Oraphim runtime registers 4 sockets and 88 properties for this node. Its main registered inputs are Input, Second Layer, Matte Layer; its main outputs are Output. The tables below are generated from the runtime registry rather than a handwritten approximation.

How to use it

1. Add Channel Process from node search. Use fusion.channel_process when you need the exact registry entry.
2. Connect a compatible Image source to Input. Add the other inputs only when the operation needs them.
3. Start with the registry defaults and adjust Preserve Alpha, Clip HDR, Stretch Second Layer first so you can see the node's effect in isolation.
4. Route Output (Image) into a compatible downstream node, viewer, or output path.
5. Preview a representative frame, change one input/control at a time, and save/reopen reusable graphs to verify persistence.

Practical example

Create a small test graph with Channel Process. Feed a compatible source into Input. Change Preserve Alpha away from its registry default and compare the result. Connect Output to a compatible downstream stage so the result is visible. Keeping this test graph small makes socket-type, context, and parameter mistakes easier to diagnose before the node is used in a production graph.

Troubleshooting

• If a connection is rejected, compare the exact socket data types in the tables above; Oraphim graph connections are typed.
• If the result looks unchanged, confirm this node is on the active path to the viewer/output and that the expected graph/resource is selected.
• If a control is unavailable, check required inputs and whether the property belongs to an internal or mode-dependent group.
• If a saved graph behaves differently later, reopen it and verify node identity, connections, and edited property values before rendering.
