Simple PBR Material Sample

This material graph sample demonstrates creation of a simple PBR material.

The Deferred PBR Material master material node is provided with the following data inputs:

  • Albedo - taken from the Albedo texture (Texture node) sampled by the Sample 2D node and multiplied (Mul node) by the color multiplier provided by the Color node of the UI group (enabling you to adjust a color value via the Parameters panel in the UnigineEditor).
  • Opacity - value (fully opaque) specified directly using a port adapter
  • Metalness - R value taken from the Shading texture using the X port adapter multiplied (Mul node) by a metalness coefficient provided by the Float Slider node of the UI group (enabling you to adjust a float value via the Parameters panel in the UnigineEditor).
  • Roughness - G value taken from the Shading texture using the Y port adapter multiplied (Mul node) by a roughness coefficient provided by the Float Slider node of the UI group (enabling you to adjust a float value via the Parameters panel in the UnigineEditor).
  • Normal - taken via the XYZ port adapter from the tangent-space Normal map data (Texture node) sampled by the Sample 2D node.
  • Occlusion - taken via the X port adapter from the Occlusion texture (Texture node) sampled by the Sample 2D node (as only the R-channel is used for the occlusion map).

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