# Spline AI - Category: AI design - Official site: https://spline.design/ai - HTML: https://www.88z.ai/en/tools/spline-ai - Markdown: https://www.88z.ai/en/tools/spline-ai.md Spline AI is an intelligent 3D generation engine built directly into the Spline design platform, designed to streamline the workflow from concept to final asset. ## What is Spline AI? Spline AI is an intelligent 3D generation engine built directly into the Spline design platform, designed to streamline the workflow from concept to final asset.By simply entering a descriptive text prompt or uploading a front-facing reference image (PNG, JPG, or WebP up to 15 MB), users can generate textured 3D models complete with base color, metallic-roughness, and normal maps in seconds. The tool integrates state-of-the-art AI models such as Hunyuan3D, Trellis 2, and Meshy, allowing users to balance geometric detail with generation speed based on their specific needs.Generated models can be downloaded as GLB files for use in Blender, Unity, or Unreal Engine, or opened directly within the Spline editor for lighting, animation, and publishing to Web, iOS, and Android platforms. Spline AI prioritizes data privacy and security, running all generation processes in the cloud without using existing user file data for training.Whether for rapid game asset prototyping, product visualization, or preparing files for 3D printing, it offers designers a comprehensive AI-assisted workflow. ## Key features - **Multimodal Gener**：Supports generating 3D objects via text-only prompts, single reference images, or a combination of both, adapting flexibly to different creative starting points. - **Selectable AI Mo**：Users can choose between Hunyuan3D (default balanced), Hunyuan 3.1 Pro (high-detail geometry), Trellis 2 (handles intersecting shapes), or Meshy (clean topology) for generation. - **PBR Material Map**：Generated models automatically include base color, metallic-roughness, and normal maps, ensuring metals look like metal and lighting behaves realistically in rendered scenes. - **Real-time Previe**：Offers shaded, clay, wireframe, and individual map viewing modes, allowing users to thoroughly inspect mesh surface details before finalizing the generation. - **Environment Ligh**：Includes four lighting rigs with dials for strength, ambient light, rotation, and exposure, plus a turntable function for全方位 model inspection. - **Asset Library Ma**：All generated image previews and 3D models are automatically saved to a personal asset library, searchable and filterable by type for easy reuse. - **Multi-platform P**：Generated scenes can be published as WebGPU/WebGL links or exported as native SwiftUI (iOS) and Jetpack Compose (Android) code, maintaining interactivity and high performance. ## How to use it 1. 1.Open the Spline editor or generation page, click the AI button on the toolbar, and select 'AI Generate'. 2. 2.Enter a description of the object in the prompt box, or upload a front-facing reference image (PNG/JPG/WebP, max 15 MB), or use both. 3. 3.Choose an AI model suitable for your needs from options like Hunyuan3D, Trellis 2, or Meshy. 4. 4.Review the four generated image previews, select the one you prefer, and let the system build the textured 3D model from it. 5. 5.Inspect the model statistics (faces, vertices, file size) and rendering effects in the editor, making adjustments if necessary. 6. 6.Download the model as a GLB file, or publish it directly to Web, iOS, and Android platforms. ## Where it fits - **Game Asset Creat**：Rapidly generate textured props, characters, or creatures, export as GLB, and import directly into Blender, Unity, or Unreal Engine. - **Product Visualiz**：Transform product photos into 3D models to showcase items from every angle on websites or online stores, enhancing user experience. - **Concept Design B**：Quickly generate 3D drafts from sketches or text prompts to test creative ideas and spatial relationships before detailed modeling. - **3D Printing Prep**：Open generated models in Spline and export them as STL files, ready for slicing software and 3D printing. ## Pricing and free quota Spline AI 3D Generation is available on all paid workspace plans (Hobby, Pro, and Max), each including a monthly allowance of AI credits.Pricing details follow the official site. ## Who it is for - 3D Designers & Artists - Game Developers - UI/UX Designers - Product Managers - Independent Creators ## FAQ ### How do I turn an image into a 3D model? Open the Generate tool, add a reference image, and pick a model.A front-facing shot of a single object works best (PNG, JPG, or WebP up to 15 MB).You get a set of image previews; pick the one you like, and Spline builds a textured 3D model from it. ### Do I need special hardware to generate 3D models? No.Generation runs in the cloud, and Spline runs in your browser, so no high-end local GPU or specialized software is required. ### Can I use generated models in Blender or Unity? Yes.GLB is the binary form of glTF, an open 3D format that Blender, Unity, and Unreal Engine can import directly. ### Does Spline AI use my file data? No.Spline AI does not use any of our users’ existing files or data for training.All user and AI data is handled by Spline on its own servers, and prompt-related data is only collected if you decide to share it as feedback. ### How many credits does one generation cost? A run is billed in two steps: generating image previews and building the 3D model.The estimated cost is shown before you send.If you only mesh an image you already generated, you are charged only for the model step. ## Tags 3D Generation · Text to 3D · Image to 3D · PBR Maps · Game Assets Features, pricing and availability follow the official site.
