The standalone Demo is a development preview. Dynamic-node additions, animated viewport fitting and AI authoring shown in the video are not part of the current launch plugin package. See the included product contents below.

MellosWidget composes Unreal Engine interfaces around typed UObject data. Build editable object panels, actions, reusable lists and shared-node directed acyclic graphs while keeping gameplay rules in your data classes.

A widget palette selects presentation by value type and role. Reuse the same data in different screens, refresh existing controls after external changes, and keep business logic independent of widget templates.

Style assets own typography, named artwork, control appearance and motion. Page scopes update existing controls and generated children. Instant, Smooth, Tech and Custom use one motion system for nodes and content, including sequential text replacement, symbol scrambling and image exchange.

An independent editor resource-validation command reports missing roles, invalid references, unsupported motion configurations, localization gaps and font coverage to Unreal Engine's Message Log before play.

Included: 12 reusable Widget Blueprints, a widget palette, a sample style, C++ source, and separate Chinese and English user guides. A minimal native example is available as a separate download; install the plugin into it separately.

Release scope: Unreal Engine 5.8 / Windows 64-bit. Projects own gameplay, replication and data synchronization. External data changes require an explicit UI refresh.

MellosWidget succeeds Mellos UMG as a separate product. Existing templates require migration to the new contracts; no automatic asset converter is included.

Gallery: Actual in-engine captures from our UMGExperiment Demo show a connected talent tree, Fantasy / Tech / Ink themes, a settings screen and elemental combat integration. The screenshots demonstrate what can be built with MellosWidget. The current download includes the reusable plugin assets listed above and the separate minimal example; the full Demo artwork, themed screens and gameplay are not included as editable project assets in the plugin purchase. The separate playable Demo above includes the assets needed to run it.
