Localize？ Localization (L10N) ● Localization is the process of adapting internationalized software for a specific region or language by translating text and adding locale specific components. Internationalization (I18N) ● Internationalization is the process of designing a software application so that it can be adapted to various languages and regions without engineering changes. #UE4DD | @UNREALENGINE

Localization Dashboard - Gather Text Gather Text Target Dependencies Text present in these targets will not be duplicated in this target. Additional Manifest Dependencies Text present in these manifests will not be duplicated in this target. Required Module Names The names of modules which must be loaded when gathering text. Use to gather from packages or metadata sourced from a module that isn't the primary game module. #UE4DD | @UNREALENGINE

Gather Text (Gather from Text Files) #UE4DD | @UNREALENGINE

Localization Dashboard - Gather Text Gather Text Search Directories The paths of directories to be searched recursively for text files, specified relative to the project's root, which may be parsed for text to gather. Exclude Path Wildcards Text files whose paths match these wildcard patterns will be excluded from gathering. File Extensions Text files whose names match these wildcard patterns may be parsed for text to gather. Should Gather from Editor Only Data If enabled, data that is specified as editor-only may be processed for gathering. #UE4DD | @UNREALENGINE

Gather Text (Gather from Packages) #UE4DD | @UNREALENGINE

Localization Dashboard - Gather Text Gather Text Include Path Wildcards Packages whose paths match these wildcard patterns, specified relative to the project's root, may be processed for gathering. Exclude Path Wildcards Packages whose paths match these wildcard patterns will be excluded from gathering. File Extensions Packages whose names match these wildcard patterns may be processed for text to gather. Collections Packages in these collections may be processed for gathering. Should Gather from Editor Only Data If enabled, data that is specified as editor-only may be processed for gathering. Skip Gather Cache Should we ignore the cached text in the package header and perform a full package load instead? #UE4DD | @UNREALENGINE

Localization Dashboard - Gather Text Gather Text Key Specifications Specifications for how to gather text from specific metadata keys. Meta Data Key The metadata key for which values will be gathered as text. Text Namespace The localization namespace in which the gathered text will be output. Text Key Pattern The pattern which will be formatted to form the localization key for the metadata value gathered as text. #UE4DD | @UNREALENGINE

Export Text / Compile Text / Import Dialogue #UE4DD | @UNREALENGINE

Localization Dashboard Export Text Collapse Mode How should we collapse down text when exporting to PO? Should Persist Comments on Export Should user comments in existing PO files be persisted after export? Useful if using a third party service that stores editor/translator notes in the PO format's comment fields. Should Add Source Locations as Comments Should source locations be added to PO file entries as comments? Useful if a third party service doesn't expose PO file reference comments, which typically store the source location. #UE4DD | @UNREALENGINE

Localization Dashboard Compile Text Skip Source Check Should we skip the source check when compiling translations? This will allow translations whose source no longer matches the active source to still be used by the game at runtime. Validate Format Patterns Should we validate that format patterns are valid for the culture being compiled (eg, detect invalid plural rules or broken syntax). Validate Safe Whitespace Should we validate that text doesn't contain any unsafe whitespace (leading or trailing whitespace) that could get lost during the translation process. #UE4DD | @UNREALENGINE

Localization Dashboard Import Dialogue Raw Audio Path Path to the folder to import the audio from. This folder is expected to contain culture sub-folders, which in turn contain the raw WAV files to import. Imported Dialogue Folder Folder in which to create the generated sound waves. This is relative to the root of the L10N culture folder (or the root content folder if importing native dialogue as source dialogue). Import Native as Source Should the dialogue for the native culture be imported as if it were source audio? If false, the native culture dialogue will be imported as localized data for the native culture. #UE4DD | @UNREALENGINE
