Autonomix

AI Developer for Unreal Engine — An autonomous AI agent that creates Blueprints, C++, levels, materials, widgets, and more inside the UE5 editor via natural language.

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 Gemini/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-reada
