In this tutorial, we dive into the concept of Physically Based Rendering (PBR), a rendering technique that simulates how light interacts with surfaces based on real-world physical properties. We’ll guide you through creating and applying simple PBR materials, explaining key elements such as base color, metallic, roughness, and normal maps. Additionally, we’ll explore how to control material domains, blend modes, and shading modes to achieve different visual effects. By the end of the video, you’ll understand how to create realistic materials and control their appearance in a 3D environment using PBR principles.
