SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps Unreal Engine developers configure module rules and build settings to create scalable, error-free modules and plugins. It covers Build.cs, TargetRules, plugin wiring, and common build errors like unresolved externals, missing includes, or IWYU violations.

Core Features & Use Cases

  • Detailed guidance on Create/Manage Build.cs and TargetRules for new modules and plugins.
  • Best practices for Public/Private dependencies, include paths, and API macro exports (MODULENAME_API) to avoid linker errors.
  • Scenarios including adding modules, plugins, and handling editor-specific dependencies with conditional compilation.

Quick Start

Create a new module by adding Source/MyModule with Build.cs alongside Public/Private folders, and update your .uproject.

Frequently Asked Questions about ue-module-build-system

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up Build.cs for a new Unreal Engine module?▼

The Unreal Build Tool uses Build.cs files to define module rules, public/private dependencies, and include paths, allowing you to create scalable, error-free modules and plugins while enforcing IWYU discipline during UE5 development.

Why does my Unreal Build Tool project fail with unresolved externals and missing includes?▼

Unreal Build Tool manages module dependencies and build rules by processing Build.cs files to configure include paths and enforce IWYU discipline, preventing unresolved externals and missing include errors during UE5 compilation.

Can I use Unreal Build Tool TargetRules to handle editor-specific dependencies?▼

Yes, Unreal Build Tool TargetRules allow you to configure editor-specific dependencies and conditional compilation, ensuring correct plugin wiring and build settings tailored for different UE5 project targets.

What is the best way to manage public and private dependencies in Unreal Engine plugins?▼

The best way to manage dependencies is by configuring Build.cs files to separate public and private module dependencies, ensuring proper include paths and API macro exports (MODULENAME_API) to avoid linker errors in Unreal Engine plugins.

Does configuring Unreal Build Tool modules require updating the .uproject file?▼

Yes, configuring Unreal Build Tool modules requires updating the .uproject file alongside creating the Source/MyModule directory with Build.cs to wire plugins and enforce correct module rules across UE5 projects.
