Normal Maps, Tangent Space, and Image-Based Lighting for Game Development - Part 3

This course teaches game developers to build Unity shaders using include files, multiple passes, macros, texture sampling, normal and height maps, ambient light, skyboxes, and diffuse and specular image-based lighting. It includes assignments and a Garden of the Sea example.
