Description

Substrate Light Reflectance - Unreal Substrate - Episode 2 is a Ben Cloward YouTube tutorial in his Unreal Substrate series, focused on how light reflectance inputs map to physically meaningful parameters inside Unreal Engine's Substrate material framework. Cloward walks through diffuse albedo, F0, and F90 and how artists should think about them relative to legacy metallic workflows.

The video explains relationships between base color, metallic, and specular sliders and what happens inside Substrate's metalness-to-diffuse-albedo conversion node. Viewers see Material Editor graphs and preview meshes that make energy conservation and highlight shape easier to reason about than with monolithic shading models.

It targets intermediate artists and technical artists learning Substrate slabs, plus programmers who support material tooling. Basic Unreal material editor experience and familiarity with PBR terminology are assumed.

The episode is free on Cloward's channel, numbered as part of a continuing Substrate playlist with earlier overview videos. Runtime is typical of his lecture-style captures with on-screen editor navigation.

Cloward's Unreal shader videos are among the most linked beginner-to-intermediate resources in Unreal rendering communities; his Substrate series is a common onboarding path after Epic's official documentation.
