# UV node The UV node outputs the vertex or fragment UV coordinates of a mesh. UV coordinates usually have two channels, but the UV node outputs four channels so you can use the remaining two channels, for example to store custom mesh data. ## Ports | **Name** | **Direction** | **Type** | **Binding** | **Description** | |:------------ |:-------------|:-----|:---|:---| | **Out** | Output | Vector 4 | None | The u and v coordinates from the mesh in the first two channels, and two extra channels. | ## Controls | **Name** | **Type** | **Options** | **Description** | |:------------ |:-------------|:-----|:---| | **Channel** | Dropdown | **UV0**, **UV1**, **UV2**, **UV3**, **UV4**, **UV5**, **UV6**, **UV7** | Selects the coordinate set to output. |
