An interface that sounds right.

Widget Blueprint CRUD with full tree manipulation, pre-built templates for HUDs, menus, settings panels, inventories and loading screens, styling and keyframed animations, plus whole game systems scaffolded for you — save/load, audio config, input remapping — with accessibility audits, colorblind modes and text scaling built in from the start.

UE5's Model-View-ViewModel framework, from MCP: authors viewmodel Blueprints with FieldNotify properties, binds widget properties to viewmodel fields with conversion functions, and configures binding and execution modes for UI that's actually data-driven instead of held together with tick events.

Aligns and measures UMG against real PIE screenshots — DPI math, anchor and offset semantics, rotation pivots for clocks and dials, calibration poses. The difference between "looks about right" and actually verified.

Full CRUD on attenuation, classes, mixes, concurrency and submixes; Sound Cue graph construction with 22 node types; MetaSound Builder integration; and one-call build_sound_cue_from_spec / build_metasound_from_spec — plus batch operations and audio health checks across the whole project, so nothing's silently clipping in the mix.
