🎯 One chat generated UMG widget.

"Use llm-dynamicui to generate a [main menu / HUD / dialog / settings] UI for [your game]."

🤖 Agent Online — if you have LLMEasyShell / LLMEasyShellLite installed, invoke the auto-registered C++ ability ui to drive this end-to-end from any LLM agent. UI skill + Agent skill are online in the skill repo.

✅ One JSON, Complete UI - Layout, widgets, and animations generated from a single .llmui file

✅ LLM-First Design - AI outputs JSON directly, no UE editor knowledge required

✅ Bidirectional Conversion - JSON → UMG Blueprint, UMG Blueprint → JSON, perfect roundtrip

✅ CommonUI Deep Integration - Auto-generates style assets (CommonTextStyle, CommonButtonStyle) + native Common widgets (CommonButton / CommonText / CommonBorder)

✅ Animation System - 15 easing functions (Linear, Quad, Cubic, Sine, Expo, Elastic, Bounce, Back) with infinite loops, ping-pong, and auto-play

✅ 24 Widget Types - Layout, Primitive, Input, CommonUI, and Effect (BackgroundBlur) widgets

✅ JSON Schema Driven - Recursive property discovery, 50+ properties auto-parsed

✅ Editor Panel + Runtime API - One-click UMG generation + AngelScript runtime widget creation

✅ Full Compatibility - Works with CommonActivatableWidget, CommonUserWidget, UserWidget

.llmui (JSON), .llmschema (Schema), UMG Blueprint (UAsset)

Version: Unreal Engine 5.7+

Dependencies: CommonUI, EditorScriptingUtilities

Modules: LLMDynamicUI (Runtime), LLMDynamicUIEditor (Editor)

Number of Blueprints: 0

Number of C++ Classes: ~30

Network Replicated: No

Documentation Link: Documentation.md in plugin folder

Example Project: Config/Samples/ folder contains example .llmui files

Supported Platforms: Windows only (currently). Mac/Linux support is pending QA verification.

The Problem

Traditional UE UI development is tedious:

• Drag widgets in editor

• Set properties one by one

• Adjust layout manually

• Create animations separately

• No AI integration

The Solution

LLMDynamicUI changes everything. One JSON file defines:

• Widget hierarchy (layout structure)

• All properties (text, colors, sizes, etc.)

• Animation tracks (with easing and loops)

LLM outputs the JSON. Plugin generates the UMG Blueprint. Done.

Example

{ "name": "MainMenu", "rootWidget": { "type": "VerticalBox", "children": [ { "type": "Text", "content": { "text": "GAME TITLE", "fontSize": 48 }, "animations": [ { "property": "RenderOpacity", "fromValue": 0, "toValue": 1, "duration": 1.0, "easing": "OutCubic", "autoPlay": true } ] }, { "type": "CommonButton", "content": { "text": "Start Game" }, "events": { "onClick": "OnStartClicked" } } ] } }

Import this JSON → Get a fully functional Widget Blueprint with animation.

1. LLM generates .llmui - AI outputs JSON with your UI definition

2. Import in Editor - Window > LLMDynamicUI Panel

3. Generate UMG - One click creates the Blueprint

4. Iterate - Modify JSON, regenerate, or export back to JSON
