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

Dive into an extensive 3-hour lecture on advanced shader techniques for game development. Explore normal maps, tangent space, height maps, and image-based lighting. Learn about multi-light support, .cginc include files, multiple passes, and Unity's lighting macros. Discover how to implement color/albedo textures, normal map intensity, and height/displacement maps. Gain insights into vertex shader texture sampling, mesh normal caveats, and the importance of ambient light. Master the concepts of image-based lighting (IBL), skybox shaders, and rectilinear skybox sampling. Enhance your understanding of diffuse and specular IBL techniques to create more realistic and visually appealing game environments.
