This tutorial follows on from our other video, Using Poliigon textures in Maya with Octane.

High quality textures are just the first part of creating realistic, believable materials. In the real world nothing is clean, even the most sterile environment will have imperfections and it's important to replicate that when creating realistic renders. 

Smudges:

  • Create a new image texture node and load in the smudges texture (use the white smudges on a black background), be sure to click on override in the color space options so the gamma is set to 1.0. 
  • Add in a add node and feed in the original gloss texture into the top input and the smudges into the bottom input. Finally feed the output of the add node into the roughness input of the Octane Shader.

Scratches:

  • Create a new image texture node and load in the scratches texture (use the greyscale black scratches on a white background)), be sure to click on override in the color space options so the gamma is set to 1.0. 
  • Connect the scratches texture to the additional bump input of the Octane Shader.
  • Adjust scaling via the texture node and strength via the Octane Shader.
