Disclaimer

This plugin requires an active API key from at least one of the supported AI providers to function. Please see our documentation for more information on how to obtain API keys.

Key Features:
  • Text-to-3D Generation: ๐Ÿ—ฃ๏ธ

    Describe any object, character, or prop in plain text and get a fully textured 3D model (GLB, FBX, OBJ, USDZ, STL). Powered by Meshy-6, Tripo v3.1, Hunyuan3D v3.1 Pro, and Hyper3D Rodin Gen-2

  • Image-to-3D Generation: ๐Ÿ“ธ

    Upload a reference image โ€” a photo, concept art, or AI-generated image โ€” and get a 3D model that matches it. Available across all 7 providers for maximum flexibility in quality, speed, and cost

  • AI Texture Generation: ๐ŸŽจ

    Generate seamless PBR texture maps โ€” base color, normal, roughness, metallic, or full PBR sets โ€” using Google Gemini. Perfect for quickly texturing blockouts or generating tileable materials on the fly

  • Reference Image Pipeline: ๐Ÿ–ผ๏ธ

    Generate clean concept art optimized for 3D generation, then feed it directly into Image-to-3D. The recommended workflow for the highest quality results โ€” all without leaving the editor

  • Auto-Rigging (Experimental): ๐Ÿฆด

    Automatically rig humanoid models with a skeleton and walking/running animations via Meshy AI. Generate a character, switch to Auto-Rig mode, and the plugin chains the workflow seamlessly using the last generated task ID

  • Remesh & Retopologize: ๐Ÿ”ง

    Optimize mesh polycount with triangle or quad topology via Meshy AI. Control target polycount, auto-sizing, and topology type โ€” perfect for bringing high-poly AI generations down to game-ready polycounts

  • Retexture: ๐ŸŽญ

    Apply entirely new AI-generated textures to existing 3D models via Meshy AI. Re-skin assets without re-modeling

  • Deep Editor Integration: ๐Ÿ› ๏ธ

    A fully custom Slate editor tab with provider selection, mode picker, prompt input, reference image preview, progress tracking with live timer, result thumbnail preview, advanced per-provider settings, and direct Content Browser import. Everything in one panel

  • Multi-Provider, One Interface: ๐ŸŒ

    7 provider options โ€” Meshy AI, Tripo AI, Hunyuan3D, TripoSR, Rodin, Trellis 2, and Google Gemini โ€” all behind a single unified widget. Switch providers with a dropdown, no code changes needed

  • Runtime + Editor: โšก

    Full feature parity. Every generation feature works both in the editor widget and at runtime via C++ or Blueprints. Ship AI-powered asset generation in your packaged game

  • Blueprint & C++ Ready: ๐Ÿ”—

    Simple Blueprint async nodes for rapid prototyping, and the same robust C++ API for maximum control. Includes utility nodes for saving models/textures to disk, creating runtime textures, and importing assets to the Content Browser

  • Effortless Server Proxying: โ˜๏ธ

    Override any provider endpoint with a single setting for corporate proxies, custom backends, or security requirements

  • Designed for Cross-Platform: ๐Ÿ“ฑ

    Works on Windows, macOS, Linux, Android, and iOS. Uses only standard Unreal Engine modules for maximum compatibility

  • Secure & Centralized Authentication: ๐Ÿ”’

    All API keys managed in one settings panel, stored in XOR-encrypted binary files โ€” never in plain text configs or source control

Supported Providers & Features

Use Cases:
  • ๐Ÿ—๏ธ Rapid Prototyping: Generate placeholder or final 3D assets from text descriptions in seconds โ€” no modeling skills required

  • ๐ŸŽฎ Runtime Asset Generation: Let players describe items, characters, or environments and generate them live in-game

  • ๐ŸŽจ Texture Workflows: Generate PBR texture sets for blockouts, or retexture existing models with completely new looks

  • ๐Ÿค– NPC & Character Creation: Generate humanoid models, auto-rig them with skeletons, and drop them straight into your game

  • ๐Ÿ› ๏ธ Editor Tooling: Build custom editor utilities โ€” combine with GenAI for Unreal's text/vision capabilities for AI-powered asset pipelines

  • ๐Ÿ“ Mesh Optimization: Use Remesh to bring high-poly AI generations down to game-ready polycounts with triangle or quad topology

Why Choose This Plugin?
  • Constantly Evolving: ๐Ÿงฌ

    We provide rapid updates to support new 3D AI models as the space moves fast. Meshy-6, Hunyuan3D v3.1 Pro, Trellis 2, and Rodin Gen-2 were all added shortly after release

  • Production-Ready and Tested: โš”๏ธ

    Every provider integration is tested with real API keys across UE 5.1โ€“5.7. The plugin handles edge cases like WebP texture conversion, compressed texture GPU readback, empty animation track crashes, and large base64 log truncation

  • 7 Providers, Best-in-Class Coverage: ๐ŸŒต

    From ultra-fast TripoSR (<1 second) to high-quality Meshy-6 with PBR and auto-refine โ€” pick the right tool for every job. Costs range from ~$0.04 to ~$0.60 per generation

  • Built by Developers, for Developers: ๐Ÿ’ป

    From the creators of GenAI for Unreal โ€” the #1 AI integration plugin on the Unreal Marketplace. Years of professional game development experience and a track record of long-term support

  • Dedicated Support ๐Ÿ“ง

Great to see more AI generation tools coming directly into the editor, thatโ€™s where they belong.

Weโ€™re building something similar with StudioTwin but as a fully integrated cloud platform rather than individual API wrappers. One plugin, one account, one credit system. We route across multiple AI providers and our own deployments behind the scenes so artists just describe what they need and get the best available result. No juggling API keys or separate subscriptions.

Early access is open if anyone wants to compare workflows: https://studiotwin.ai/

This is nice Victor, But our plugin is much more easier to use and has wider provider support. Itโ€™s also rapidly improving with many other features already in the testing phases.
