Creating an MDL in Substance 3D Designer
This series is a great starting point for discovering MDL graphs and working with MDL materials in Designer.
The metallic clearcoat material covered in this tutorial is impossible to define only through textures: it features two separate specular highlights that behave differently: one rougher metallic coat with speckles, and one very smooth clear topcoat.
"In this course we cover the basics of creating an MDL in Substance 3D Designer. We will be recreating a physically-based metallic/roughness shader as an MDL to illustrate the core concepts of the MDL nodes and graph. In the second video we will look at creating a car paint MDL."
