In this course, Javier Perez covers how to render materials created in Substance Designer using Marmoset Toolbag. His process begins with setting up a mesh in Maya, importing it into Marmoset, where he will cover some specific panels and settings used for rendering. Finally, he will show how he uses Photoshop for a final polish pass.
