Hey ya!
Hello everyone after eons waiting I finally got my accounts setup, here I created a new tutorial explained step by step about how to create real life complex materials for UE, the goal of this tut is for you to understand what are you doing with your maths rather that only show you how to do cool materials.
You can check the trailer right here:
