Editing Class Defaults values in Blueprints/data assets.

V0.2.0 — December 15, 2025

New Features

Universal Asset Explanation — The AI can now explain Materials, Behavior Trees, Animation Blueprints, and Widget Blueprints, in addition to standard Blueprints. Works for both the full asset and for selected nodes within the graph.
Export Summaries — Export the AI’s explanation of any asset or node selection to a .md or .txt file for documentation.
C++ Filesystem Access — Added tools for reading from and writing to external .cpp and .h files.
Improved Widget Generation — Creating complex UMG layouts from prompts is now significantly more powerful and reliable.

Improvements

Clean Blueprint Layouts — Generated Blueprints have a better node layout now.
More Potent Code Generation — The AI is now much smarter, using a built-in API list of common engine functions to generate more accurate and reliable code.
Faster AI Responses — Added a “Feasibility Check” to prevent the AI from attempting unsupported tasks.

Fixes

UTF-16LE Support — Fixed critical crashes for international users by adding support for UTF-16LE file encoding.
Stability — Resolved several crashes that could occur during complex Blueprint generation.
Includes numerous other smaller bug fixes for a smoother experience.

V0.1.5 — November 18, 2025

The plugin is now fully self-sufficient. When using an external AI assistant, the third-party API (OpenAI, Gemini) is no longer used. The external assistant (like Claude Desktop/Cursor) now reads the plugin’s rules, generates the code itself, and sends it to Unreal just for compilation.
Stability overhaul and crash proofing.

V0.1.1 — October 27, 2025

Fixes & Improvements

Fixed a critical editor crash in the full project scanner caused by nullptr Blueprint ParentClass pointers.
Completely re-architected the “Blueprint Explanation” feature, replacing the slow and unreliable async “job/poll” system with a fast, synchronous tool. The AI now gets the raw data and synthesizes the explanation itself. You can have a Blueprint, a folder, or the entire project explained.

New Features

Data Asset Creation — New tools for the AI to create User Defined Structs and Enums directly from chat. The AI populates these assets with relevant variables based on creative prompts (e.g., “create a struct for RPG stats”).
Construction Script Support — The AI can now generate code directly into a Blueprint’s Construction Script.
Fixed a bug where the insertion logic wasn’t working when using Claude Desktop/Cursor. You can now add code after a selected node again.

V0.1.0 — October 20, 2025

A groundbreaking update, transforming the plugin into a complete AI Copilot for Unreal Engine. Full Model Context Protocol (MCP) integration — connect directly to AI clients like Cursor and Claude Desktop for a seamless, conversational workflow.

Key New Features

Project-Wide Intelligence — Scan your entire project to create a knowledge base. The AI can now generate detailed performance/memory reports and answer high-level questions like “Where is the health system implemented?”
Advanced Scene Population — Instantly populate selected volumes or areas with hundreds of Static Meshes and Blueprints, featuring full randomization for location, rotation, and scale.
Complete UI (UMG) Scaffolding — Build and lay out complex UI hierarchies from a single prompt. The AI can create panels, buttons, and text, and control layout properties like anchors, alignment, and padding.
Conversational Code Refactoring — Select any Blueprint nodes and get a safe, non-destructive, optimized function as a suggested replacement.
Context-Aware Workflow — The AI is now aware of your context. It can create assets in your currently focused Content Browser folder.
Expanded Asset & Scene Control — Full support for creating Materials, applying them to multiple actors, and spawning any actor type. The AI can also list and select actors in the World Outliner.
Complex System Generation — Scaffold entire gameplay systems (e.g., a complete Health system with damage/heal functions) from a single high-level command.

V0.0.6 — September 8, 2025

Added support for Local LLMs (Ollama, LM Studio). Still very experimental.

V0.0.5 — September 1, 2025

New Features

Node Insertion — Select any node in an existing graph and add new logic seamlessly after it.
