Rendering Pipeline Mastery Hub: The Industry Foundation Prac

Within the context of physically based rendering (PBR) as presented in "The Complete Physically Based Rendering (PBR) Course 2026: From Zero to Expert!", which of the following material properties is LEAST directly represented by a texture map in a typical PBR workflow, aiming for maximum energy conservation and realistic light interaction?

Considering the fundamental principles of energy conservation in PBR, as emphasized in "The Complete Physically Based Rendering (PBR) Course 2026: From Zero to Expert!", what is the primary consequence of an improperly configured specular workflow where the specular color of a dielectric material exceeds the Fresnel reflectance at normal incidence (e.g., > 4%)?

In advanced PBR techniques discussed in "The Complete Physically Based Rendering (PBR) Course 2026: From Zero to Expert!", the concept of "anisotropy" is crucial for simulating certain surface types. Which of the following best describes the effect of increasing anisotropy on the specular highlight of a material?
