If you are used to using the standard procedural C4D materials, such as the checker shader, you can easily recreate the same thing with Arnold.
One of the nice things about using Arnold in Cinema 4D is that you have the ability to create pretty much anything by connecting nodes together. Here, creativMotion shows how you can create the ultimately useful checker shader, in Arnold.
It’s a great workflow to be able to see a near instant preview of the shader that you are creating, as it is being built.
CreativMotion notes that this technique may seem convoluted at first, but walking through it helps, and you will be able to better understand how to create shaders in Arnold.
