Troubleshooting & FAQ

Frequently Asked Questions#

Can I export Widget (UMG) and Animation Blueprints?#

Yes! The exporter supports standard Actors, Pawns, Characters, UMG Widget Blueprints, and Animation Blueprints. Widget components translate into BindWidget properties and animation graphs map into NativeUpdateAnimation.

Does the generated code compile immediately?#

In most standard setups, yes. However, if your Blueprint references custom third-party plugins or complex custom C++ modules, you will need to add those module names into your project's Build.cs file.

Will exporting overwrite my existing Blueprint?#

No. The exporter only inspects the Blueprint to generate C++ code. Your original Blueprint asset is completely untouched and safe.

Common Solutions#

Unrecognized type in generated header#

  • Cause: The Blueprint uses a struct or enum defined in another plugin.
  • Fix: Add the required plugin module to your project's Build.cs PublicDependencyModuleNames.

Toolbar button does not appear#

  • Cause: Editor extensions need to reload after initial install.
  • Fix: Restart Unreal Editor to ensure the toolbar hooks register with the Asset Editor.
