Generate 3D models and audio from text or images inside Unity. Multi-provider AI pipeline with batch processing, post-processing, rigging, animation, and built-in budget tracking.What It Does ⚡AI Asset Pipeline is a comprehensive Unity Editor tool that lets you generate 3D models and audio assets using leading AI services — without ever leaving the Unity Editor. Describe what you need in plain text, supply a reference image, or feed in multiple photos, and the pipeline will produce game-ready 3D assets complete with PBR textures, rigging, and animations. An integrated audio generation module lets you create sound effects and music from text prompts using Stability AI's Stable Audio technology.Whether you're rapid-prototyping, populating a game world, or exploring AI-assisted workflows, AI Asset Pipeline provides a professional, production-grade toolset to accelerate your asset creation.IMPORTANT — API Keys & Usage Costs ⚠️This tool does NOT include AI credits or API access. You must sign up with one or more of the supported AI providers and supply your own API keys. All generation costs are billed directly by the respective provider (e.g., Meshy, Tripo3D, Stability AI, OpenAI, Perplexity AI). Typical costs range from 0.50–5 per full-pipeline asset, depending on the provider and post-processing steps you enable.To help you stay in control of your spending, AI Asset Pipeline includes a dedicated Budget & Wallet window that:Queries live wallet/credit balances from every configured providerDisplays per-provider pricing references so you know costs before you generateLets you set daily budget limits with automatic 80% and 100% threshold warningsTracks per-provider and per-operation usage history over timeProvides cost estimates directly in the pipeline UI before you click "Generate"You are always in full control of how much you spend.Generation Modes 🎨Text → 3D (Direct) Enter a text description such as "medieval treasure chest" and receive a fully textured 3D model. Supported by both Meshy and Tripo3D.Image → 3D Supply a reference image — concept art, a photo, or an AI-generated image — and convert it into a 3D model with PBR textures.Multi-Image → 3D Provide 2–8 images from different angles for photogrammetry-style reconstruction. Ideal when you have multiple reference views of an object.Full Pipeline (Text → Prompt Optimization → Image → 3D) The flagship mode. Enter a rough text idea. The pipeline:Optimizes your prompt using GPT-4.1 or Perplexity Sonar for maximum generation qualityGenerates a high-quality reference image via Stability AI, DALL-E, or LetzAIConverts the image into a 3D model with PBR texturesAn optional Image Confirmation step pauses the pipeline after image generation so you can preview, accept, regenerate, or cancel before 3D conversion begins — saving credits when the image isn't right.Audio Generation Generate sound effects, ambient audio, or music from text descriptions using Stability AI's Stable Audio 2.0 / 2.5. Configure audio type, duration (up to 60 seconds), BPM, looping, and output format. Optional prompt optimization ensures best results.Post-Processing Pipeline 🔧After initial 3D generation, enable any combination of these optional post-processing steps (each a simple checkbox toggle with inline cost estimates):Remesh / Retopology — Cleans and optimizes mesh topology for better edge flow and reduced polygon countRetexture — Applies entirely new AI-generated textures using a custom style prompt and optional reference imageAuto-Rigging — Automatically adds a humanoid skeleton to your model with configurable character heightAnimation — Adds animation clips (idle, walk, run, jump, attack, or any custom animations) to rigged modelsFormat Conversion — Converts models between formats: GLTF, USDZ, FBX, OBJ, STL, 3MF with optional quad remesh and face limit controlMost post-processing steps can also be used standalone on existing models — not just on freshly generated ones.Supported AI Providers 🔌3D Model GenerationMeshy — Text→3D, Image→3D, Multi-Image→3D, Remesh, Retexture, Refine, Rigging, Animation, PBR texturesTripo3D — Text→3D, Image→3D, Multi-Image→3D, Remesh, Retexture, Rigging, Animation, Stylization, Format Conversion, PBR texturesImage GenerationStability AI — Stable Diffusion 3 (Medium, Large, Ultra) for high-quality reference imagesOpenAI DALL-E — DALL-E 3 for creative, artistic reference imagesLetzAI — Flux 2 model with configurable quality, creativity, and resolution settingsPrompt OptimizationOpenAI — GPT-4.1, GPT-4.1 Mini, o4-mini via the Responses APIPerplexity AI — Sonar and Sonar Pro modelsAudio GenerationStability AI Stable Audio — Stable Audio 2.0 and 2.5 for sound effects, ambience, and musicEvery provider is a ScriptableObject asset that you configure and assign to a Pipeline Config.
