Advanced Vibe Coding capabilities through agentic development for broad Unreal workflows across content, worldbuilding, UI, animation, AI, and technical tooling
AGENTIC UNREAL WORKFLOWS
Use AI to coordinate Blueprint graphs, StateTrees, asset operations, data setup, audio, and technical editor workflows without breaking flow.
WORLD, UI, AND CONTENT TOOLS
Create landscapes, foliage, materials, widgets, assets, and project setup changes from the same AI-assisted workflow.
LEARN & UNDERSTAND
Ask AI to explain systems, trace workflows, inspect APIs, debug logs, and discover best practices across gameplay, rendering, audio, tools, and content pipelines.
IN-EDITOR AI CHAT

WHAT IS VibeUE?
VibeUE brings AI directly into Unreal Engine with a powerful In-Editor Chat Client that can understand, explain, and modify Blueprints, materials, landscapes, foliage, widgets, assets, animation, audio, StateTrees, and project settings through natural language. No external tools required!
Built by the community, for the community. VibeUE is fully open-source and welcomes contributions from developers worldwide. Learn how existing Blueprints work by asking AI to explain them, discover what each node does, trace execution flow, and understand material graphs. Then create, modify, and optimize - all from within the Unreal Editor.
