This guide shows how to build a centralized Material System Definition in Unreal that generates thousands of material combinations deterministically, integrates with backend systems using logical keys instead of asset paths, and provides validation at every layer.
Real example: Luxury watch configurator with 2,000+ materials reduced authoring time from weeks to hours using bulk generation and Material Layer stacking.
Covers: deterministic naming, Color Sets, Finish libraries, backend sync, validation workflows, and editor tooling. Part 3 of the Configurator Engine series.
