Technical Details
PluginSmith is an Unreal Engine Editor plugin that automates building, validating, and packaging plugins and projects across multiple engine versions (4.27 → 5.7). It integrates with Unreal’s IPluginManager and Unreal Automation Tool (UAT) to produce Fab Marketplace–compliant ZIP packages, complete with validation, logging, and engine-specific compilation. It supports both Blueprint and C++ automation APIs, enabling command-line and in-editor packaging flows..
