Subtitles UMG provides more control over the built-in Subtitles and Dialogue system. This is a simple-to-use plugin that lets you to bind an event to the engine's internal event when new subtitles are called from Play Dialogue events.
It's useful for cinematic sequences, narrative events and virtual production when you want to customize the look of the built-in Dialogue system without writing any C++.
The text from these events is exposed to you in the linked function, allowing you to take control of subtitle parameters (e.g. font, size) and displaying them in different views (e.g. desktop, mobile, VR).
A widget base class "SubtitleUMG" can be sub'classed as a User widget, with a Blueprint event, for when the subtitles are called. A global event is also available.
