Autonomix

🤖 Autonomix — AI Developer for Unreal Engine
    A production-grade Unreal Engine editor plugin that uses AI to autonomously create, modify, and manage entire game projects — directly inside the editor.

Overview

Autonomix brings agentic AI capabilities into the Unreal Engine editor. Instead of just generating code snippets, it operates as a fully autonomous developer — creating Blueprints via T3D injection, editing C++ source files, managing levels, materials, meshes, widgets, PCG graphs, animations, and more — all through a conversational chat interface embedded in the editor.

Think of it as Cursor/Roo Code, but for Unreal Engine — with deep engine integration that goes far beyond text editing.

> How is this different from UE 5.7's built-in AI assistant? Unreal Engine 5.7 includes a contextual F1 AI helper focused on *guidance* — explaining features, suggesting workflows, and linking documentation. Autonomix is a *doer*: it executes tool calls that modify your project (create Blueprints, edit C++, build materials, spawn actors), with every action checkpointed, auditable, and undoable. They're complementary — one explains, the other builds.

Key Differentiators

- T3D Blueprint Injection — Creates entire Blueprint node graphs in a single transaction using UE's native T3D format (the same format the editor uses for Ctrl+C/Ctrl+V). No node-by-node API calls.
- GUID Placeholder System — AI uses human-readable tokens (LINK_1, GUID_A, NODEREF_Entry) that get resolved to real engine GUIDs automatically, preserving cross-node pin links.
- 85+ AI Tools — Not just file editing. Blueprint creation, component management, material graphs, animation systems, PCG, Enhanced Input, performance profiling, renderer settings, Behavior Trees, Sequencer, DataTables, Python scripting, viewport vision, PIE automation, and more.
- Git-Based Checkpoint System — Shadow git repo per session lets you save, restore, and diff any point in the AI's work.
- Agentic Tool Loop — The AI autonomously plans, executes tools, verifies results, and iterates until the task is complete.
- Multi-Provider Support — Works with Anthropic Claude, OpenAI, Google Gemini, DeepSeek, Mistral, xAI, OpenRouter, Ollama, LM Studio, and any custom OpenAI-compatible endpoint.
- Smart Context Management — Automatic conversation condensation, sliding-window truncation, token budget management, and tool result eviction for long sessions. Old tool results are automatically summarized once the AI has processed them.
- Token-Optimized Tool Results — Blueprint readbacks use a compact connection verification format instead of raw T3D exports, reducing tool result tokens by 80-90% per call while preserving full verification capability.
- Fuzzy Diff Applicator — Levenshtein-distance fuzzy matching for code edits, preventing failures from minor whitespace or formatting differences.

🛡️ Session & UX Improvements (v1.3)
- Stop Button — Single-click cancel for any in-progress AI operation. Send button transforms into a Stop button during processing, driven by a unified EConv
