Comprehensive best practices guide for modern Unreal Engine 5.x development. Covers Epic's strategic direction toward modern systems (GAS, Enhanced Input, StateTree, MetaSounds, Niagara, PCG, CommonUI, World Partition, Game Feature Plugins, Gameplay Tags), the "research first" philosophy of always checking for newer UE systems before implementing, C++ vs Blueprint decision making, data-driven design, asset management, project organization, naming conventions, performance optimization, and debugging with Unreal Insights. Use when the user asks about UE best practices, modern UE5 workflows, which system to use, old vs new UE systems, recommended approaches, project setup, code organization, performance tips, Blueprint vs C++ decisions, naming conventions, or when starting a new feature and needing guidance on the right UE system to use.

It uses an adaptive white, gray, or pale-beige substrate, no more than two printing inks, active negative space, terse human language, and strong serif/grotesk/mono typography without making retro styling the default or copying a source composition, wording, logo, or artwork. Produce both the final generation prompt and the generated raster image unless the user explicitly asks for prompt only.
