What this node does
Samples uv surface data for downstream field or geometry operations.
The current Oraphim runtime registers 6 sockets and 4 properties for this node. Its main registered inputs are Mesh, Value, UV Map; its main outputs are Value, Is Valid. The tables below are generated from the runtime registry rather than a handwritten approximation.

How to use it
- Add Sample UV Surface from node search. Use
geometry.sample_uv_surfacewhen you need the exact registry entry. - Connect a compatible
Geometry3Dsource to Mesh. Add the other inputs only when the operation needs them. - Start with the registry defaults and adjust Value, UV Map, Sample UV first so you can see the node's effect in isolation.
- Route Value (
Float) into a compatible downstream node, viewer, or output path. - 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 Sample UV Surface. Feed a compatible source into Mesh. Change Value away from its registry default and compare the result. Connect Value 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.
