UI Widget Builder — Automate Photoshop UI → UMG Widget Blueprint Conversion

Hey everyone,

I wanted to share a plugin I built called UI Widget Builder — it automates the process of converting Photoshop UI designs into organized UMG Widget Blueprints in Unreal Engine 5.

Anyone who’s worked on a UI-heavy project knows the drill: an artist designs a menu in Photoshop, and then someone has to manually rebuild that entire layer hierarchy in UMG — naming widgets, setting anchors, wiring up interactions. Every design iteration means doing it again. This plugin is meant to remove that repetitive setup work.

How it works

  1. Design your UI in Photoshop using a set of supported layer naming prefixes
  2. Run the included Photoshop JSX exporter — generates a layout.json file + Textures folder
  3. Open UI Widget Builder in Unreal Engine (Tools → UI Widget Builder)
  4. Import the exported data to auto-generate the widget hierarchy, root screens, and layout structure
  5. Customize/extend the generated widgets as needed
  6. Re-import updated designs using saved presets and a clean re-import option

Core Features

  • Automated UMG Widget Blueprint generation
  • layout.json + Textures import pipeline
  • Organized widget hierarchy creation
  • Root screen management
  • Portrait and landscape UI size support
  • SafeZone / ScaleBox / SizeBox wrapper support
  • Preset Manager for reusable import settings
  • Clean re-import with generated asset cleanup

Optional Blueprint Logic

  • Button interaction logic
  • WidgetSwitcher tab logic
  • Close on Key/Back/Escape
  • Slider, checkbox, and progress bar helpers
  • Click/hover sound + music playback setup
  • ScrollBox auto-scroll, video/media playback helpers

Text & Layout Support

  • Font mapping with missing-font fallback
  • UTF-8 and RTL text support
  • Resolution-based layout generation

Good for: menus, HUDs, inventory UI, shop interfaces, mobile UI, launcher UI, settings screens, character selection, pause menus, and rapid UI prototyping.

Happy to answer any questions about the workflow, the layer naming conventions, or how it handles specific UI cases — this came out of solving my own repetitive setup pain, so genuinely curious whether it’d be useful for other people’s pipelines.
