How to use Volume Material node in Oraphim

Type ID: motion.volume.material
Category: Color

What this node does

The Volume Material 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 32 properties for this node. Its main registered inputs are Field, Volume; its main outputs are Material, Volume. The tables below are generated from the runtime registry rather than a handwritten approximation.

How to use it

1. Add Volume Material from node search. Use motion.volume.material when you need the exact registry entry.
2. Connect a compatible Field source to Field. Add the other inputs only when the operation needs them.
3. Start with the registry defaults and adjust Density, Coverage, Density Scale first so you can see the node's effect in isolation.
4. Route Material (Material) 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 Volume Material. Feed a compatible source into Field. Change Density away from its registry default and compare the result. Connect Material 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.
