Custom Editors | Unity Shader Code Basics 08
With a custom shader GUI, we can bring together all the features we've built and combine them into a mega PBR shader.
Physically Based Rendering | Unity Shader Code Basics 07
PBR lets us describe objects using their physical properties - albedo, metallic, smoothness, height, etc. - and the light model works out how the lighting should look.
Unity Shader Graph Basics (Part 6 - Lighting Basics)
With physically based rendering (PBR), we describe the physical properties of a surface, such as albedo color, normals, smoothness, metallic, and light emission.
