After a couple of larger updates by Arnold Renderer some parts of the tutorial is now old and not up to date. Anders Langlands addon to Arnold is deprecated and not possible to use anymore. But many of the principles is still possible to use, and that’s why I do not remove this tutorial form Youtube. Thank you for your understanding :)
As the title says, in this leather material tutorial I show my main method of creating materials. In Photoshop I make the material base often from an image. Sometimes I find this image on the web or a I take my own picture. It's made into a square and then made seamless for ease of use in 3D. Then processed it in Bitmap2Material or Materialize (only on windows) to create different texture maps. Then mixed together in Arnold Render.
