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.

Note

This node is a Subgraph node: it represents a Subgraph instead of directly representing Unity's shader code. Double-click the node in any Shader Graph to view its Subgraph.

Create Node menu category

The UVCombine node is under the Utility > High Definition Render Pipeline category in the Create Node menu.

Compatibility

node is supported on the following render pipelines:

Built-in Render Pipeline Universal Render Pipeline (URP) High Definition Render Pipeline (HDRP)
No No Yes

For more information on the HDRP, see Unity's HDRP package documentation.

node can also be connected to any Block node in either Context. For more information on Block nodes and Contexts, see Master Stack.

Inputs

node has the following input ports:

Name Type Description
UV Channel Mask Vector 4 Select which UV channel you want to use for your UV coordinates by entering a 1 in the corresponding default input on the port:
  • X: UV channel 0
  • Y: UV channel 1
  • Z: UV channel 2
  • W: UV channel 3
Set all other default inputs to 0. You can also connect a node that outputs a Vector 4.
UV Tile and Offset Vector 4 Use the port's default input to specify the amount of offset or tiling that you want to apply to your shader's UV coordinates:
  • Use X and Y to specify the tiling.
  • Use W and Z to specify the offset.
You can also connect a node that outputs a Vector 4.

Outputs

node has one output port:

Name Type Binding Description
UV Vector 2 UV The final UV output, after selecting a UV channel and, if specified, any tiling or offset.

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 > Fabric > Silk or HDRP > Fabric > CottonWool shader, as described in the Unity User Manual section Creating a material asset, and assigning a shader to it.

  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.
