Hello, I uploaded an 8 hours of free tutorial to my youtube channel.
https://www.youtube.com/playlist?list=PLXfmekZqahrV8qwKuT0nH3UI-dB-hpFag
It covers procedural texture creation of some electronic hard surface devices with tessellated geometry, and application of the material on Octane Render using Modo.
I hope you like it!
