UV Tiling and Offset Sample

This material graph sample demonstrates how to implement UV adjustment (tiling and offset) in a material.

The Texture node enables you to select a texture asset via the Parameters panel in the UnigineEditor. The Sample2D node samples data from the texture in accordance with the specified UV. Albedo RGB data for the Deferred PBR Material master material node is taken from the output of the Sample2D node via the xyz port adapter (selecting the first three components of the RGBA vector), the Opacity value (fully opaque) is specified directly via the port adapter.

Adjustable UV coordinates (with tiling and offset applied) are passed to the UV port (float2) of the Sample2D node as a result of mathematical operations implemented via nodes in the following way:

  1. The Add node increases UV coordinates taken from the UV0 node by the offset values (provided by the first Float Slider node adjustable via the Parameters panel in the UnigineEditor).
  2. The Mul node multiplies the resulting UV coordinates taken from the output port of the Add node by the tiling values (provided by the second Float Slider node.

Finally, the data output from the master material node is passed to the Final Material node.
