reviewer: Codex Game Studio seed review date: 2026-06-17 source-link: https://dev.epicgames.com/documentation/en-us/unreal-engine/ engine: unreal version-reviewed: 5.5 tags: unreal,plugins roles: tools-programmer,engine-programmer,unreal-specialist workflows: prototype,bugfix,architecture-review,qa-plan # Unreal Plugin And Package Reference ## Purpose Guide plugin/package use without adding hidden runtime dependencies. ## Guidance - Prefer package-manager or marketplace sources that are reviewable in the project. - Record plugin version, install surface, and rollback risk. - Avoid requiring plugins for lightweight prototypes unless explicitly justified. ## Validation - Prefer project-local engine commands and Codex Game Studio project validation before readiness claims. - Record unknown version-specific behavior as a risk instead of presenting it as confirmed. - Keep this reference selected by relevance; do not load every engine reference for one task.
