In this shader tutorial for Unreal and Unity, we begin a short series on creating a Diablo-style health or mana meter. It's a crystal sphere filled with bubbling colored liquid that rises or drains to show the player's health. Today we focus on creating the data to create the sphere including depth, normals, diffuse lighting, and a mask.
