GenAI for Unreal

Overview

GenAI for Unreal (by Muddy Terrain Games) is a production-ready Unreal Engine plugin that connects 30+ AI model APIs — including GPT-5, Claude Opus/Sonnet, Gemini, Grok, DeepSeek, and local Ollama models — directly to Blueprints and C++. It handles chat completions, streaming, text-to-speech (OpenAI TTS, ElevenLabs, Google TTS), speech-to-text (Whisper), image generation (DALL-E, Imagen), real-time voice (Gemini Live), and function calling. Developers can build AI-driven NPCs, dynamic quest systems, or adaptive dialogue without writing any HTTP client code.

Best For

• Unreal developers who want AI-driven gameplay mechanics (dynamic dialogue, adaptive quests) without building an HTTP layer
• Studios using local Ollama models who need Unreal engine integration without cloud API calls
• Devs who want a single plugin supporting any LLM rather than being locked to one provider
