UI Materials

Unreal Motion Graphics (UMG) uses materials as a sort of paint for widgets. Materials can be used to create a cheap, dynamic looking UI widget. The tutorials in this section teach you how to use math to create a desired effect in a material through specific material nodes. You can create materials that move, glow, and much more.
