PromptModel - AI 3D Model Generator + Library

No sign-up. No API keys. No subscription. No per-generation fees. No leaving Unity. Just one-click 3D model generation from text or images. Type what you want — a wooden barrel, an ornate sword, a sci-fi crate. Click Generate. In under 60 seconds, a Unity Prefab is downloaded, automatically processed with PBR materials, given 4 LOD levels, centered pivot, and (optionally) dropped into your active scene. This asset uses Microsoft TRELLIS (CVPR 2025) via fal.ai for 3D generation, and FLUX schnell for the text-to-image step. AI-Generated Models Showcase | Online Documentation 🎁 INCLUDED MONTHLY ALLOWANCE 50 generations are issued every month with your purchase. 50 generations is enough for a substantial prop library — barrels, crates, weapons, furniture, architectural details, sci-fi parts. The allowance is issued automatically every 30 days; no need to remember anything. 💡 WHY PROMPTMODEL ✅ NO SUBSCRIPTION — buy once, generate every month. No recurring fees, no per-generation costs. ✅ TEXT OR IMAGE INPUT — type a prompt for prop concepts, or drop a reference photo for image-to-3D when you have a specific look in mind. ✅ FULLY AUTOMATIC IMPORT — GLB download, PBR material extraction, LOD generation (50%/25%/10% triangles), pivot centering, and prefab wrapping all happen automatically. ✅ AUTO-SPAWN INTO SCENE — optional checkbox drops the finished prefab into your active scene at world origin, selected and framed in the Scene view. ✅ GENERATE 4 VARIATIONS AT ONCE — one click on any prefab → 4 alternative versions in a 2×2 picker → import the ones you like. Different seeds, same prompt, meaningfully different geometry. ✅ BUILT-IN MODEL LIBRARY — every model you generate lands in a searchable browser (Window ▸ PromptModel ▸ Model Library): a category sidebar with Favourites and your own custom categories, a sortable thumbnail grid with a card-size slider, and a drag-to-orbit / scroll-to-zoom 3D preview showing triangle and vertex counts. ✅ ZERO RUNTIME OVERHEAD — all scripts are Editor-only. Your build size and runtime performance are completely unaffected. ✅ INSTANT ACTIVATION — enter your Asset Store invoice number, click Verify, and start generating. No website signup, no account creation. 🎨 WHAT YOU CAN GENERATE Game props — barrels, crates, treasure chests, weapons, tools, lanterns Furniture — chairs, tables, stools, beds, cabinets, shelves Architectural details — pillars, signs, banners, debris, ruins Fantasy items — staves, potions, scrolls, runes, magical artifacts Sci-fi assets — consoles, antennas, containers, mechanical parts Natural objects — rocks, tree stumps, mushrooms, crystals, fossils Stylized characters — small statues, figurines, animals (single subject) And much more — any object you can describe or photograph 🚀 HOW IT WORKS 1. Enter your Asset Store invoice number (from your purchase confirmation email) and click Verify. 2. Choose Text mode or Image mode in the dropdown. 3. Text: type a prompt like "wooden treasure chest with iron bands". Image: drop a PNG/JPEG/WebP into the drop zone (or drag a Texture2D from Project view, or click to browse). 4. (Optional) Type a name. Leave blank to auto-derive from your prompt. 5. Click GENERATE. 6. The cloud AI generates a textured mesh. The Unity package downloads it, applies PBR materials, generates LOD0/1/2/3 with UnityMeshSimplifier, centers the pivot, and saves a Unity Prefab. 7. With Auto-Spawn checked, the prefab also drops into your active scene at world origin, selected and framed. Want alternatives? Right-click any PromptModel-generated prefab → Generate similar → 4 variations stream in as thumbnails → tick the ones you like → Import. ⚠️ WHAT'S INCLUDED VS NOT INCLUDED PromptModel produces single-subject 3D props for any Unity project. Specifically what's covered: ✅ Single-object models — props, items, furniture, architectural pieces ✅ PBR materials — albedo, metallic, roughness textures ✅ Auto-generated LODs at 100%, 50%, 25%, 10% triangle counts ✅ Centered
