SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Unreal Engine packaging failures are hard to diagnose because Build, Cook, Stage, Package, Deploy, and Run are distinct phases with different failure modes. This Skill structures the entire release pipeline so you can produce reproducible artifacts, isolate the first causal error, and verify builds on clean target hardware. ## Core Features & Use Cases - Pipeline orchestration: Separate and control Build/Cook/Stage/Package/Deploy phases via Project Launcher profiles, AutomationTool BuildCookRun, or CI, with a defined artifact contract. - Cook and content validation: Define cook roots, maps, chunks, and Primary Asset ownership; inspect manifests and containers instead of masking issues with -cookall. - Release hardening: Manage symbols, crash reporting, signing/encryption keys, config staging, runtime dependencies, patches, and DLC against a retained base release. - Use Case: A Shipping build crashes on a clean machine with an unreadable callstack. Use this Skill to match the exact build ID to retained private symbols, capture the runtime log, and identify the missing staged runtime dependency. ## Quick Start Use the unreal-packaging-deployment skill to diagnose why my packaged Unreal Engine 5.8 game is missing cooked assets in the Shipping build.

Frequently Asked Questions about unreal-packaging-deployment

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

FAQPage Schema
How do I package an Unreal Engine 5.8 project from the command line?▼

Use AutomationTool BuildCookRun for unattended packaging, or create a Project Launcher profile and capture its generated UAT command. Run RunUAT.bat BuildCookRun -Help against your installed engine before adding flags, and parameterize only project, platform, output, version, and credentials in CI.

Why are assets missing in my packaged Unreal build but work in PIE?▼

Missing packaged assets usually mean the asset has no cook root: a map, hard dependency, Asset Manager rule, or Primary Asset Label. Trace the owning rule, run a clean By-the-Book cook, and verify inclusion in cook manifests and container listings instead of using -cookall.

What is the difference between Development, Test, and Shipping build configurations?▼

Development keeps logs, console, and profiling for daily testing; Test is a Shipping-like QA build with selected diagnostics; Shipping is the distribution candidate with full optimization and stripped tools. Shipping can still produce symbols, which should be stored securely rather than staged publicly.

How do I build a patch or DLC for a released Unreal game?▼

Retain the exact released binaries, containers, manifests, registry, config, keys, and version metadata, then build the patch against that base using the platform's approved pipeline. Test base-to-patch upgrade and fresh install on a clean device, and investigate unexpected file churn.

Why does my packaged game fail to launch on a clean machine?▼

Clean-machine launch failures typically come from missing prerequisites or undeclared runtime dependencies such as DLLs that must remain loose files. Declare third-party libraries through RuntimeDependencies in .Build.cs and verify architecture, search paths, and platform SDK requirements on the target.

How do I symbolicate a crash from a Shipping build?▼

Produce and retain Shipping symbols privately, then symbolicate against the exact executable and build identity that crashed. Symbols from a rebuild of the same source are not guaranteed to match, so never substitute rebuilt equivalents.
