# UVCombine node

The UVCombine node lets you select which UV channel you want to use for mapping your shader to geometry in your application. You can also choose to apply tiling and offset to your UV coordinates.

<td>Select which UV channel you want to use for your UV coordinates by entering a <code>1</code> in the corresponding default input on the port:
<ul>
<li><strong>X</strong>: UV channel 0</li>
<li><strong>Y</strong>: UV channel 1</li>
<li><strong>Z</strong>: UV channel 2</li>
<li><strong>W</strong>: UV channel 3</li>

<ul>
<li>Use <strong>X</strong> and <strong>Y</strong> to specify the tiling.</li>
<li>Use <strong>W</strong> and <strong>Z</strong> to specify the offset.</li>

## Example graph usage

For an example use of the UVCombine node, see either of the HDRP's Fabric shaders.

To view these Shader Graphs:

1. Create a new material and assign it the **HDRP** &gt; **Fabric** &gt; **Silk** or **HDRP** &gt; **Fabric** &gt; **CottonWool** shader, as described in the Unity User Manual section [Creating a material asset, and assigning a shader to it](https://docs.unity3d.com/Documentation/Manual/materials-introduction.html).

2. Next to the **Shader** dropdown, select **Edit**.

Your chosen Fabric's Shader Graph opens. You can view the UVCombine node, its Subgraph, and the other nodes that create HDRP's Fabric shaders.
